The farmer who has access to and knows how to use what science knows about soils, plants, animals, and machines can produce abundance of food though the land be poor. Nor need he work nearly so hard and long. He can produce so much that his brothers and some of his neighbours will move to town to earn their living." ––T W Schultz (1964) (Noble Prize winner for Economics, 1979)</p> <p>Dear friends and colleagues, at some point, I will come back to this statement by Prof. Theodore Schultz.

A. Okere [email protected] T. O. Okoronkwo [email protected] C. C. Apeh [email protected] E. Unuabonah [email protected] C. O. Okeke [email protected] <p><em>The growing policy concern on the environment cannot be significantly addressed without strict measures in the case of POME. POME is a highly environmental pollution produced by smallholder oil palm mill operators that affects farming activities and its environment. This study was done to analyze the effects of POME on smallholder oil palm farming activities in Agbo, Delta State with the objectives of examining the socioeconomic features of the farmers and determining the effects of POME on their farming activities. A purposive sampling method was employed to randomly select a sample size of 30 smallholder oil palm farmers and analyzed with descriptive statistics and regression model. The result showed that majority of them were in their middle / old age of 40 to 60 years with 66.7% married while 60% of them had family size of 6 and above and 83.7% of 11 years and above farming experiences. The regression result showed that POME had significant and negative effects on age, labour and plant nutrients at 0.05%, farming experience and farm size at 0.1% and household size at 0.01% with positive and significant effects on soil management practices at 0.1% and annual income at 0.05%. The study recommends a synergy between the farmers and biotechnological and allied research centres in connection with the Ministry of Environment through education/ training on the use of biotechnological tools, POME treatment technologies and intensified soil management practices in their operations to control, maintain and regulate their activities for a friendly and sustainable environment.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Integrated Application of Wood Ash and Inorganic Fertilizers on The Growth and Yield of Garden Egg (Solanum aethiopicum L.) 2023-03-21T00:09:55+01:00 N.

Ibeawuchi [email protected] <p><em>Wood ash is one of the commonly available organic wastes in Nigeria because firewood is a common source of fuel for both rural and urban dwellers and can become an important alternative source of inorganic potassium especially for farmers in areas with acidic soils. Treatments consisted of the application of inorganic fertilizer sources (0 kg ha-1, 130.44 kg ha-1 urea and 300 kg ha-1 NPK 20:10:10) and wood ash (0 t ha-1, 5 t ha-1 ash and 10 t ha-1 ash) to garden egg seedlings in the field using 3 x 3 factorial experiment in randomized complete block design with three replications. Main effect of wood ash showed significant (p ≤ 0.05) fruit yield in this order: 10 t ha-1 of wood ash &gt; control &gt; 5 t ha-1 of wood ash. The main effect of inorganic fertilizer sources on fruit yield followed this sequence: 300 kg ha-1 NPK 20:10:10 &gt; 130.44 kg ha-1 Urea &gt; control. The interaction of 10 t ha-1 of wood ash and 300 kg ha-1 NPK 20:10:10 produced highest fruit yield (57 t ha-1) while 5 t ha-1 of wood ash produced lowest fruit yield (10.70 t ha-1). Therefore, the application of integrated 10 t ha-1 of wood ash and 300 kg ha-1 NPK 20:10:10 for improved growth and yield of garden egg is recommended to farmers in Awka.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Regeneration of sectioned seeds of Telfairia occidentalis Hook F.

Obdiebube [email protected] <p><em>There is an acute shortage of Telfairia seeds during growing season, due to seed recalcitrance and the alternative uses to which the seeds are put. An experiment was conducted to determine the extent to which the seed of Telfairia occidentalis can be sectioned for the regeneration of propagules and to assess the growth response of the sectioned seeds. Pre-germinated seeds were sectioned into minisetts up to 32 per seeds. These were nursed for three (3) weeks and transplanted to the field in randomized complete block design with 3 replications. Whole seeds and seeds sectioned into two had the highest seedling emergence and reached their peaks at the end of 2 weeks after sowing. The least value of 30% seedling emergence was produced by seeds sectioned into 32. The vine growths of the whole seed (141 cm) and those sectioned into two (107 cm) were consistently and significantly higher than those of smaller seed sections that ranged from 16 - 84 cm. The relatively higher vigor expressed by whole seed over the sectioned seeds is probably due to the relatively higher food reserve in the former. The result obtained in this experiment has shown that it is possible to regenerate Telfairia occidentalis propagules by the use of seed sectioned up to 16. It is recommended that future studies should address the need to upgrade the seedlings emergence of sectioned seeds to achieve 100% survival in the nursery, and excellent plant stand in the field.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Intercropping Impact on Weed Dry Matter, Soil C/N content and Sugarcane (Saccharum officinarum) Productivity 2023-03-22T07:09:28+01:00 M.S. Bassey [email protected] <p><em>The effects of intercropping on weed dry matter, soil C and N, and sugarcane productivity were investigated at Badeggi, Nigeria in 2016 and 2017. The results revealed that application of Sugarcane + Groundnut intercropping produced lower weed dry matter comparable to Sugarcane + Soybean intercropping which significantly increased growth and yield attributes of sugarcane. Application of Sugarcane + Groundnut intercropping, resulted in a comparable germination count, Tiller count, plant and stalk height with Soybean intercropping. It generated taller plants and stalks, more girth, brix content, millable cane, stools and cane yield. Similarly, Sugarcane + Groundnut intercropping and Soybean intercropping produced comparable stalk height and brix content. In conclusion, application of Sugarcane + Groundnut intercropping or Soybean intercropping effectively controlled weeds, increased Soil C and N, plant and stalk height, girth, brix content, millable cane, stools and cane yield of sugarcane.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Impacts of Selected Plant Extracts on Three Solanacea Cultivars Nursery Development 2023-03-22T07:19:18+01:00 B.

Onwuchekwa [email protected] <p><em>A trial was carried out at the nursery unit, Faculty of Agriculture, Nnamdi Azikiwe University, Awka to evaluate the impacts of three plant extracts(Siam, Bitter leaf and Moringa) on the growth parameters and biomass of three solanacea nursery crops(tomato, garden egg and pepper).The Randomized completely block design experiment was replicated three times. Despite crop type, moringa extract significantly enhanced early germination and emergence % of all the tested crops, Throughout the course of the work bitter leaf extract produced the biggest fresh and dry bio masses, tomato(28.13g and 3.37g), pepper(84.10g and 10,0g) and garden egg(50.10g and 6.10g).Bitter leaf extract also produced the tallest plants followed by moringa extract. While leaf area of the tested crops were significantly improved by the extracts, leaf number seemed to be controlled genetically. Plant extracts contain bio stimulants, bio pesticides, hormones, vitamins and minerals that can promote plant growth and increase plant response on stress .Generally, these plant extracts are readily available, cheap and easy to prepare and apply. We therefore recommend the use of these extracts in raising nursery crops and growing crops in the field especially bitter leaf and moringa extracts which are environmentally friendly and sustainable.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Productivity of Sweet Potato (Ipomoea batatas (L.) Lam.) Cultivars in Ibadan, Nigeria 2023-03-22T07:40:21+01:00 A.O. Lawal [email protected] <p><em>A field experiment was conducted to evaluate the productivity of 20 sweet potato (Ipomoea batatas (L.) Lam.) cultivars in Ibadan, Nigeria. The cultivars evaluated were obtained from the Department of Agronomy sweet potato germplasm multiplication field and were planted 30cm apart on the crest of ridges 3m long in a randomized block complete design (RCBD) with four replications. Observation and data were collected on number of leaves, main vines length, percentage survival, percentage ground cover, number of tubers per plant, fresh root and shoot yield. Result showed that there were significant differences (P &lt; 0.05) among the cultivars evaluated. The number of leaves produced by the cultivars ranged from 109 to 205. Cultivar Eruwa-cream produced the highest number of leaves, while cv ‘Barth’ had the least at 12 WAP. Mean length of the main vine ranged from 84.69cm (cv TIS 86/0356) to 231.54cm (cv 440293). Percentage survival and percentage ground cover ranges from 80.0% (cv V005) to 100.0% (cv TIS 86/0356) and 25.3% (cv V003) to 79.0% (cv V084) at 10 WAP respectively. Maximum number of tubers (3.45/plant) was produced by cultivar 199034.1; this was significantly higher than the least (0.65/plant) which was obtained from cultivar V003. Cultivars V087 and Benue produced maximum fresh root yield (17.72 to 18.92 t/ha) while cultivars 440293, Benue, TIS 86/0356 and Eruwa-cream produced significant higher fresh shoot yield than all the other cultivars (12.13 to 16.42 t/ha). This study revealed the potentials of different cultivars for diverse use ranging from breeding, weed suppression, to consumption.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Analysis of Sustainable Small Scale Catfish Farming in South Eastern Nigeria 2023-03-22T07:44:30+01:00 N. R. Chiekezie [email protected] Ozor M. U. [email protected] E. C. Nwankwo [email protected] C. O. Ositanwosu [email protected] N.J. Obiekwe [email protected] <p><em>Small scale Catfish farming involves the rearing of catfish under controlled conditions for socio-economic benefits. It is regarded as excellent aquaculture specie because it grows fast, tolerates extreme temperature, and has a good feed conversion rate. Engaging in small scale catfish production is a way of substantially improving the demand-supply gap currently experienced in the industry. The study examined the socio-economic characteristics of the small scale catfish farmers in the study area, analysed the cost and returns of farmers and examined the influence of socio-economic characteristics on Net-income. Primary data used for the study was collected using well-structured questionnaires which were administered to sampled catfish farmers. In analyzing the data, descriptive statistical tools (frequency counts, means and percentages), enterprise budgeting techniques (Gross margin, Net-farm income) and Multiple Regression Analysis were used to analyse the data. The Return on Investment was ₦1.51 and it implies that the catfish production enterprise generated 1.51 times more income than expenses incurred for the production. In addition, the result indicates a Gross ratio of 66% and a Profitability Index (PI) of 0.34 which means that for every naira earned as revenue, 0.34kobo was returned to the farmer as net income. Out of the nine independent variables included in the model, five; (age, educational attainment, experience, flock size and membership of farmer’s society) were statistically significance while the rest were not significance. This result indicated that catfish production is a highly lucrative enterprise to venture into in the study area.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Effect of Selected Organic Soil Amendments on Soil Physico-Chemical Properties, Growth and Yield Of yellow Pepper (Capsicum annum) 2023-03-22T07:54:28+01:00 Ike C.

The experiment was laid out in a Randomized Completely Block Design (RCBD) with three (3) replications. Treatments used were 10t/ha cassava peel biochar (CPBC), 10t/ha poultry manure (PM), 10t/ha cow dung (CD) and 5t/ha+5t/ha of their various combinations with one control. Morphological data were collected at two weeks interval after transplanting. Data collected were subjected to ANOVA. Significant mean differences were separated using LSD(0.05). At 12WAP, plants that received a combination of PM and CP had significantly higher heights, while the widest leaf area (116.6cm2) was obtained from those that had CD.Highest fruit weight per plant was recorded with cow dung (0.63kg), while cow dung + poultry had the highest number of fruit (170.3). The pH of the amended plot ranged from 4.73-4.99. The exchangeable bases (Ca2+ and Mg2+) were significantly higher in the plot amended with cassava peel biochar with values of 1.76cmol/kg and 1.44cmol/kg, compared to other amendments. There was also, significantly higher Organic Carbon values in the plots amended with Poultry manure. Based on the results, it could be deduced that the plot amended with cow dung + poultry manure significantly improved the soil fertility. Therefore, should be recommended for yellow pepper production in the study area.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Early and Late-Season Maize Landraces Performance on Selected Weed Control Practices 2023-03-22T08:18:17+01:00 I.

This study was laid out as a 3x4 factorial experiment in randomized complete block design (RCBD) with three replications. The selected cultivars was the main factors (Oka Bende, Oka Abakaliki and Oka Nsukka) while the four weed control method (Check [No weeding], Hoe weeding, Pre-emergence and post emergence) consisted of the sub-factor. The selected maize landraces responded positively to the weed control methods especially ‘Oka Nsukka’ and ‘Oka Bende’ in both seasons and adapted easily in Igbariam. Oka Nsukka, in the early season, gave the best grain weight per 100 seeds followed by Oka Bende while Oka Abakaliki had the best grain yield in the late season planting. The results obtained indicated that, a combination of pre-emergence herbicide and hoe weeding at 6WAS ensured that the weeds are adequately controlled and yield maximized.</em></p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Growth and Yield Responses of two Accessions of Bitter Leaf to Stem Pruning 2023-03-22T08:30:53+01:00 U.N.

Okonkwo [email protected] <p><em>A two season (rainy and dry seasons) experiment was conducted to determine the effects of stem pruning on growth and leaf yield of two accessions of bitter leaf in 2021 and 2022 cropping seasons. The experiment was carried out at the Demonstration Farm of the Department of Crop Science and Horticulture, Nnamdi Azikiwe University, Awka, Anambra State, Nigeria. The two accessions (Nimo and Nnewi) received four levels of stem pruning which were no pruning, pruning to 1, 2 and 3 stems. The experiment was laid out as a 2 x 4 factorial in randomized complete block design (RCBD) and replicated three times. The result indicated that stem pruning had significant (P&lt;0.05) effect on the growth and leaf yield of bitter leaf. The tallest plants, highest number of leaves, widest stems, highest leaf fresh and dry weight were observed in plants that were pruned to 3 stems while unpruned plants significantly (P&lt;0.05) produced the lowest mean values for both growth and leaf yield. Growth and leaf yield did not show significance among the accession though results showed that Nimo accession produced higher number of leaves, tallest plant and highest fresh leaf yield in the two seasons. Combined effect of stem pruning and accessions showed that pruning Nimo accession to 3 stems produced most vigorous plants and highest leaf yield. Considering the results obtained, stem pruning of bitter leaf, especially Nimo accession, to 3 stems was recommended for farmers in Awka since it recorded most vigorous plants and highest leaf yield.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Soil Physicochemical Properties, Growth and Development of Sweet Melon (Cucumis melo L.) as Influenced by some Organic Amendments at Awka, South Eastern Nigeria 2023-03-22T08:37:40+01:00 A.O.

The experiment was laid out in randomized complete block design (RCBD) with five treatments, replicated three times. The treatments were: Bat manure (10t/ha), Pig manure (10t/ha), Dry neem leaves (10t/ha), Poultry manure (10t/ha), and a control (0t/ha). Data collected were subjected to Analysis of Variance (ANOVA) using Genstat4th edition statistical software. Means were separated usingFisher’s Least Significant Difference (F-LSD) at 5% probability level. The results obtained showed that the application of organic amendments had significant effects on some soil physical properties but did not significantly affect any of the chemical parameters tested. Meanwhile, some growth parameters studied as well as the yield component showed significant differences among the various treatments at 3, 6 and 9weeks after planting (WAP). Bat Guano recorded the highest values for most physical properties, growth parameters and fruit weight, and is closely followed by poultry manure. Though soil chemical properties did not show statistical significant differences, application of organic amendments resulted to increased value of soil organic carbon, Total N, pH, CEC, and exchangeable bases. Bat manure though scarce, is recommended for farmers to be used in the production of Sweet Melon in the study area for higher yield and an alternative manure source for sustainable soil fertility management.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Adoption of Sustainable Farming Practices amidst Climate Change Incidence by Crop Farmers in Ebonyi State, Nigeria 2023-03-22T09:29:32+01:00 E.

C. Okoye [email protected] <p><em>Most developing countries including Nigeria are seriously affected by climate change. The role of indigenous peoples in protecting global forests and therefore regional and global climate stability has been widely recognized. The causes of deforestation in Anambra State are urbanization, land clearing for farming, bush burning for hunting, over-exploitation of medicinal plants, inadequate forest management techniques, highways and building construction. This paper suggests how indigenous communities in Anambra State can sustain their ability to use little available resources to respond to, withstand, adapt and mitigate the effects of climate change through forest restoration. There are 179 communities (Town Unions) spread throughout 21 local government districts in Anambra State. Anambra State Association of Town Unions (ASATU) where each community is represented has a women's wing that unites all the women in the State. It is intended that each community will contribute 1000 tree seedlings, for a total of 179000 tree seedlings. Each community's women shall be responsible for planting the trees in the designated locations. In the foreseeable future, the 179,000 trees planted will lower greenhouse gas emissions that worsen climate change. It would not only reduce the effects of heat waves, floods, and droughts brought on by climate change but would also have several positive economic and social effects. If 675 trees per acre would sequester around 20 tons of CO2 annually for 30 years, it implies that 179000 tree seedlings in Anambra State can sequester 5303.7 tons of CO2 in 30 years if planted.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Effect of Planting Methods on the Growth and Yield of Carrot (Daucus carota L) in Humid Tropical Zone 2023-03-22T09:51:55+01:00 E.

Two planting methods, direct sowing and transplanting were used as treatments for the experiment, which was laid out in a Randomized Complete Block Design (RCBD) and replicated four times. Data was collected on the growth, yield and root marketability. The collected parameters were statistically analyzed by analysis of variance table and means were separated using Least Significance Difference (LSD) at 5 percent level of significance with the GENSTAT 2014 Edition. The results showed no significant variation between the planting methods on the stem girth and leaf number at some dates, while transplanting significantly varied (P&lt;0.05) from direct sowing at 4, 6, 8 and 10 WAP. Planting methods did not affect some parameters (plant biomass, root length, number of roots harvested, fresh weight of leaves, and fresh weight of roots), rather they were statistically similar. Transplanting influenced significantly the root diameter, while the harvest index showed statistical difference between the planting methods, with direct sowing varying significantly. Direct sowing also significantly influenced the root marketability parameters; root uniformity, marketable yield and total marketable root yield percetage. From the results presented, direct sowing had significant effect on root marketability, which is paramount in commercial carrot production. It is thereby recommended that for optimum carrot production and marketability, carrots should be directly sown.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Characterization and Consumption of Edible Insects among Households in Oji River Local Government Area, Enugu State, Nigeria 2023-03-22T10:13:41+01:00 C.

Purposive sampling technique was used to select one hundred and twenty (120) respondents used for the study. Data were collected with structured questionnaire and interview schedule. Data were analyzed using descriptive statistics while the hypothesis was tested using simple regression analysis at 5% level of significance. The results revealed that males especially middle aged were more involved in the consumption of edible insects. Large family size of the respondents could be their reason for consuming edible insects to supplement their protein intake. Majority of respondents have basic education hence are well informed of the nutritional value of insects. Majority of the respondents were civil servants and spent between ₦10,000 - ₦20,000 per month on consumption of edible insects. Majority (100%) of the respondents enjoyed eating winged termite, cricket, larva of a species of butterfly (Wiwi or Nwigu) and honey from bee. The hypothesis showed that socio-economic characteristics did not significantly affect the level of consumption of the insects.

The research was conducted at the fish processing unit of the Department of Fisheries and Aquaculture Management, Nnamdi Azikiwe University, Awka. A total of 12 matured catfish, 6 males and 6 females which weighed 1kg each were used for the study. After fish preparation, a total of four fish (2 males and 2 females) were smoked in three different smoking kilns using the three wood types. The organoleptic properties of the smoked catfish were analyzed by ten member panel while shelf life was determined by the period of mold and insect infestation. The results indicated that there was no significant difference (P&gt;0.05) in the effects of these wood types on the organoleptic properties assessed. However, catfish smoked with the African velvet tamarind wood had the most preferable organoleptic qualities with a mean score of appearance (4.20±0.92a), aroma (4.30± 0.82a), taste (4.70± 0.67a), and texture (4.10± 0.86a). This was followed by catfish smoked with Gmelina wood with a mean score of appearance (2.90 ±0.88a), aroma (3.00± 0.94a) taste (3.00± 0.67a), and texture (2.90± 1.19a), while catfish smoked with Neem wood had the lowest mean score of appearance (2.00± 0.67a) and texture (2.50± 0.85a). It was also observed that there was no insect attack in all the smoked fish samples during the period of storage. However, catfish smoked with Neem wood showed the highest severity to mold attack (3.00) while fish smoked with Gmelina wood showed no mold attack (0.00). Therefore, these results indicated that fish processing with the use of these woods is effective in extending the shelf-life of smoked African catfish. As a result, the study suggests that the use of African velvet tamarind wood in smoking fish should be adopted to improve the organoleptic properties of smoked catfish which would also increase its profitability.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Effect of Charcoal on Soil Physico-Properties in Ndele, Rivers State: Implication for Organic Farming 2023-03-22T10:34:05+01:00 G.

The findings revealed that T2 (1:1) contaminated soil and top soil had the best growth vigour in terms of shoot height (4.36 cm) and stem diameter (1.34cm) and its leave mumber followed the best (94.6) and there is significant differences at (p&gt;0.05) level of significance. It can be inferred from the study that Adansonia digitata can be planted at mechanic garages and contaminated soil for cleaning the soil pollution and environment. Further research can be intensified for improvement of the species in terms of economics and ecological benefits it possess.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Sensory Evaluation and Physicochemical Qualities of Maize-Based Flaked Snacks Complemented with Mucuna Pruriens Seed Flour 2023-03-22T22:54:39+01:00 C.

Maize was cleaned, tempered, decorticated, milled and sieved to obtain maize flour. Mucuna pruriens seed was soaked (twice for 6 h respectively with change of water), dehulled, boiled (1 h), dried (70ºC) and milled into flour. The five Maize-Mucuna seed flour ratios were formulated as follows: 95:5 (EFA), 90:10 (EMU), 85:15 (PRO), 80:20 (UZY) and 100:0 (ABC – control). The snacks proximate composition, functional and sensory qualities were evaluated. With the addition of Mucuna pruriens seed flour the moisture content of the samples had no significant difference (p &gt; 0.05) while significant increase (p &lt; 0.05) existed in the ash and protein contents. Sample with 90:10 Maize:Mucuna flour (EMU) had the lowest value of 7.20% while sample with 80:20 Maize:Mucuna seed flour (UZY) had the highest protein value of 11.59%. Swelling power increased significantly (p &lt; 0.05) with inclusion of Mucuna pruriens seed while water absorption capacity decreased significantly (p &lt; 0.05). Sample with 80:20 Maize:Mucuna flour (UZY) had the lowest water absorption capacity (183 g/ml). The control sample ABC (100:0 Maize:Mucuna) had the highest overall acceptability score (8.33) and significantly differed from the other samples. Inclusion of Mucuna pruriens seed significantly reduced the overall acceptability of the snacks. This research showed that maize-based snacks could be complemented with up to 20% Mucuna pruriens seed flour which could help decrease protein-energy malnutrition.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Effects of Process Variables (Soaking Time and Drying Temperature) on Proximate Composition of Oven Dried Maize (Zea mays) Pap 2023-03-22T23:08:40+01:00 J.O.

For the heavy metals analyses, concentrations of lead in the samples ranged from 0.00 to 4.00 x 10-3 mg/g. Apart from sample FFV which gave 0.00, all other samples showed lead contamination higher than Codex maximum limit of 0.3 x 10<sup>-3</sup> mg/g. Mercury levels ranged from 0.10 to 0.40 x 10<sup>-3</sup> mg/g, which were below the permissible guideline level of 0.5 x 10<sup>-3</sup> mg/g as set by Codex for fish. This suggests that all the fish samples were well below permissible levels for mercury contamination. Chromium found in samples did not exceed the recommended daily intake. Arsenic and Cadmium were not detected in any of the samples. For microbiological analysis, the total heterotrophic bacterial count ranged from 1.0 x10<sup>2</sup> to 3.8 x 10<sup>2</sup> Cfu/g, total coliform count ranged from 1.4x102 to 2.5x 102 Cfu/g, total Salmonella count ranged from 1.0 x 10<sup>2</sup> to 1.2 x 10<sup>2</sup> Cfu/g, total Vibrio count ranged from 1.0 x 10<sup>2</sup> to 1.5 x 10<sup>2</sup> Cfu/g, and total fungal count ranged from 1.0 x 10<sup>2</sup> to 1.5x 10<sup>2</sup> Cfu/g.

Both accessions seeds for planting were relatively of the same size and weight. At 21 days after planting, 77% of the riverine seeds emerged as against 72% of the local race. The Randomized Complete Block Design (RCBD) Experiment consisted of Upland and Riverine telferia accessions whole seeds as the treatments. They were each planted ten seeds on 4x1m beds (plots) and replicated five times. The riverine accession also produced more leaves, and longer vines at WAP1 and 2 before the two accessions leaf numbers and stem lengths became equal. The probable cause of its early start and better performance might be due to higher soil and environmental temperatures when compared with the relatively lower soil temperatures common in the riverine environment. The riverine accession also had the biggest vine girth and larger leaf area which accounted for its higher vine and leaf harvest at WAP 4 (213.70kg/ha) and WAP11 (4.00t/ha) as against upland accession WAP4 (77kg/kg) and WAP11 (2.68t/ha) harvests. Riverine accession started flowering early at 13 WAP (91 days), while upland accession started at 14 WAP (98days). Riverine accession also started fruiting at 16 WAP (112 days), while upland accession started fruiting at 23 WAP (161 days). Therefore, to achieve maximum production of telferia in Awka rainforest zone of Nigeria, riverine accession is recommended.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Biochemical and Sensory Characteristics of Dairy-Tigernut Yoghurt using Ginger as Bio-Preservative 2023-03-23T03:43:16+01:00 A.

Soil samples were collected from Research Farm of National Root Crops Research Institute, Ginger Station, Kajuru, Kaduna State, Nigeria. Bacteria were isolated and identified based on colonial and biochemical characteristics. The assessment for the potential of the bacterial isolates to degrade glyphosate and paraquat herbicides was carried out using microcosms study. The bacterial isolates were phenotypically identified as Proteus sp., Acidovorax sp., Micrococcus sp., Staphylococcus aureus, Bacillus sp. and Aeromonas sp. Among the isolates, Acidovorax sp. and Aeromonas sp. had the highest potential to utilize glyphosate and paraquat as sole source of carbon. In the presence of glyphosate Acidovorax sp. and Aeromonas sp. had cells count of 1.30×108cfu/g and 1.90×108cfu/g respectively. However, in the presents of paraquat as a source of carbon Acidovorax sp. and Aeromonas sp. had the counts of 1.90×107cfu/g and 2.60×106cfu/g respectively. The quantifications of glyphosate and paraquat herbicides residues in amended soil using GC/MS shows that Acidovorax sp. have degraded 77.1% while Aeromonas sp. 88.1% of glyphosate.

C. Onyili [email protected] Jacinta Ukamaka Ezenwenyi [email protected] C.J. Nzekwe [email protected] S.O. Ezenwankwo [email protected] <p>Trees in the urban environments play an essential public health role because of their ability to absorb atmospheric carbon di oxide (CO2) through photosynthesis and thus, stored CO2 as tree biomass. Increase in population growth, industries, automobile uses, urbanization, cooking as well as concrete landscape have continued to degrade the natural environment, increasing heat and increasing the amount of greenhouse gas emissions such as CO2 in the Urban environment. Hence, there is a need to improve urban green efforts. This work reviewed the potentials of urban trees and their role in carbon sequestration. Several approaches have been used to investigate the ability of urban trees to sequester carbon. Their ability to increase carbon sequestration and storage for climate change mitigation actions cannot be overemphasized. Studies have revealed that apart from the direct storing of carbon by urban trees, they as well reduce CO2 emissions by cooling ambient air and allowing residents to minimize annual heating and cooling. Carbon dioxide concentration due to vehicular emission can also be minimized with roadsides trees. Studies have also exposed that when trees are planted near buildings, they can indirectly reduce carbon emissions by moderating the amount of energy that is required for space cooling. This work concluded that urban dwellers need to recognize and articulate the prominence of trees as a vital component of the urban setting. The selection of different tree species with high biomass and efficiency of trapping and fixing carbon is therefore recommended in plantation programme in urban areas.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Response of Turkey Growers Fed Fermented Shea Butter Cake Based Diets with Fullzyme® Supplementation 2023-03-23T04:38:08+01:00 P.C.

Poultry production being seen as a way out of this problem is faced with climate change challenges. Smallholder broiler farmers were the most vulnerable due to low copping infrastructural capacity. This study, therefore, investigated the determinants of factors influencing the level of mitigation of heat stress (HS) on broiler by farmers in Oyo state. The study employed a systematic sampling technique using registered members of the Poultry Association of Nigeria. Structured questionnaire was used to collect data: demographic, socioeconomic profile, institutional factors, perceived heat stress and coping methods. Data were analyzed using descriptive statistics and multinomial logit regression α=0.05. The study revealed that majority (76.7%) were male, mean age=48years. The average years of education and rearing experience were 12 and 6 years respectively. Majority (71.67%) accessed extension/vet doctor services, while only (23.3%) accessed credit. Temperature was perceived to be highest in January-March, while extremely cold weather was perceived in August. The symptoms of HS identified were gasping, wing raising, docility, reduction in feed, increased water intake, panting, weight loss, slow growth rate, pest and disease infestation, vaccine failure and increase mortality. Multinomial logit result showed all the independent variables to positively influence the level of farmers’ mitigation except sex and household size. Age, sex, access to credit and farmers’ income, household size, education, rearing experience, labour used and stock size were significant at 1% and 5%. Access to credit and training were recommended.</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Perceived Effect of COVID-19 Pandemic on Rural Farming Households in Nigeria 2023-03-23T04:49:12+01:00 A. P Obot [email protected] <p><em>The COVID-19 breakout in the world prompted the Nigeria government to enforce a lockdown measure at the end of March which came as a shock to small-scale farmers as movement restrictions were implemented by security operatives across the country which prevented many farmers to gain access to their fields. Some experts opined that the lockdown situation culminated in low food production, enmeshed within other COVID-19 crises like loss of livelihoods, high food prices among other issues.</em><br><em>The study employed descriptive statistics and the result showed that the farmers were aware of the COVID-19 pandemic. This restriction on movement of human and goods resulted to farmers loss of their means of livelihood and also reduced their purchasing power (money) thereby making them more vulnerable to food insecurity. As showed in the result, the monthly farm income, farm produce sold decreased during the pandemic while the cost of farm inputs (labor, fertilizer, herbicide and transportation) increased during the pandemic. From the result above, the COVID-19 pandemic drastically reduced the purchasing power of the farming households and access to nutritious food became difficult.The study therefore recommend that government and relevant organizations should support rural farmers to build their disaster resilient against future disaster. And also, to provide support or grants to rural farmers as to minimize the shock as a result of the COVID-19 pandemic and also to cushion the effect of the virus outbreak on rural farming households.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Analysis of Value Addition of Cassava Products in Nasarawa State, Nigeria 2023-03-23T04:53:11+01:00 M.

The study described the personal characteristics of the respondents; identified the causes of the conflict between the farmers and the nomads; described the perceived socio-economic effects of conflicts and identified the coping strategies adopted by the farmers. Frustration-aggression and conflict theories guided the study. The primary data collected from 120 respondents using well-structured questionnaire were analysed with mean and multiple regression analysis. The findings revealed that women dominated crop farming by 61.67%, mean age was 42.83 with a household size average of 6 persons and mean size farm land of 2.45 hectares. The perceived causes of the conflict were land encroachment, crop damage by cattle, killing of stray cattle, inadequate grazing reserves for the nomads, indiscriminate bush burning and hatred for one another. The perceived socio-economic effects of the conflicts were reduction in cultivable farmlands, little or no seed/cutting for the next planting season, disruption in the transportation of farm produce and destruction of human lives and property. This study also showed that the coping strategies adopted by the farmers were formation of vigilant groups (86.67%), income diversification (85%) and combination of arable farming with other cash crops (71.67) amongst others. The study therefore recommends that the government should address issue of climate change, establish ranches, implement the open grazing ban and provide coping loan for farmers affected by the conflict.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Analysis of Climate Change Perception by Farming Households in Ohaozara Local Government Area of Ebonyi State, Nigeria 2023-03-23T05:01:33+01:00 J.

Specifically, it described socioeconomic characteristics of smallholder rice farmers, ascertained the perceived attitude of farmers towards the use of ICT tools, analyzed the extent of use ICT tools and determined the significant relationship between smallholder rice farmers and their level of use of ICT. Data were collected with a structured questionnaire from 476 randomly selected smallholder rice farmers. Collected data were analyzed using descriptive statistics of mean threshold and Spearman Bivariate correlation. The result showed that smallholder rice farmers were relatively young because rice farming is physically demanding and old age can pose a problem to the cultural operations. It was discovered that the use of ICT tools is a source of motivation to both the extension agents and farmers’ thereby promoting learning, and ICT can be said to propel knowledge. The result on relationship between farmers and their level of use of ICT shows that a unit increase in farmer’s attitude will increase the level of use of ICT tools/format by 0.237 unit. It was recommended that government and other relevant bodies should ensure that ICT facilities are installed in rural communities, necessary trainings should be slated for smallholder rice farmers on the use of ICT tools/format by appropriate authorities to boost their confidence and reliance on ICT.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Factors Affecting Shea Nut Collectors’ and Shea Butter Producers’ Willingness to Adopt Improved Shea Seedling in North-Central Nigeria 2023-03-23T05:48:50+01:00 I.D.

Structured questionnaires were used to collect data from the respondents. Descriptive statistics and net farm income analysis were used to analyze the data obtained. The result of the socio-economic analysis showed that all the respondents (100%) were males and all had formal tertiary education. Also, 50% of the respondents were mostly between the ages of 31- 40 years and had an average of 7 years of experience in the fish farming business. The majority of the respondents derived their capital largely from personal savings and spent an average total expenditure of N610,242.2 and earned an average gross income of N1,100,000. Gross margin analysis revealed a gross margin of N579,096 with a net farm income of N599,758 implying that for every 1N invested in the fish farm business, there was a return of N1.11. This study concluded that fish production in the study area is highly profitable. The study also revealed that despite the high profitability of the fish farm business in Awka, the fish farmers still face some serious problems such as high feed costs, fish diseases, high cost of fish seeds, high labor costs, and inadequate power supply. It is suggested that government involvement in fish farming will support these practicing fish farmers and also encourage unemployed youths to engage in fish farming.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Determinants of Agricultural Export and Trade Liberalization in Nigeria 2023-03-23T05:56:12+01:00 O.

Rural farming communities in Nigeria have suffered varying degrees of climate vulnerabilities resulting in wanton destruction of live and property. To offset ravaging impacts of climate change, rural communities in Benue and Kano State developed coping strategies in the form of deforestation for arable agriculture, firewood marking, logging, charcoal production, furniture/wood working and wanton exploitation of non- forest resources. These coping strategies rather destroyed the landscapes and increased vulnerabilities in the communities. Climate change adaptation pilot project component of the “Building Nigeria’s Response to climate change” (BNRCC) Project was experiment in Daudu and Falgore communities of Benue and Kano State respectively to alleviate the increasing vulnerabilities of the rural communities. The locals adopted various sustainable climate change adaptation initiatives to build resilience.

In Nigeria, the impacts of climate change will further aggravate the plights of many indigenous and exotic tree species as climatic variability may limit the ability of forest trees to quickly adapt to the changing climate. This study focused on the assessment of open grown tree species diversity in the Nnamdi Azikiwe University, Awka, Nigeria which is considered as a crucial task to design strong conservation action strategies. Open grown tree species with diameter at breast height (Dbh) ≥10 cm in the study area were identified and recorded. Data collected were analyzed using descriptive statistics and alpha diversity analysis. A total number of 479 trees distributed among 25 tree species and 17 families were identified, with high Shannon-Weiner diversity index (2.50) and Simpson dominance index (0.88). The study indicated high species variability within the study area with Fabaceae family having the highest diversity of 4 species. Other important families dominating the study area include Apocynaceae, Lamiaceae, Moraceae and Myrtaceae with same number (2) of species. The study concluded that there is a huge presence of indigenous and exotic tree species in the study area and some are no longer found in most natural forests underscores the potentials of the campus as an important live gene bank. The study therefore recommends the need for policy intervention to aid the identification, documentation and conservation of forest tree resources in the University.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Evaluation of Flora Composition and Utilization in Ikwe Game Reserve, Igbor, Gwer L.G.A., Benue State, Nigeria 2023-03-23T06:41:27+01:00 L.

This study was carried out to determine the species composition, percentage distribution, and structure and utilization level at the study area. The point centered quarter (PCQ) method and the step point line technique (SPLT) were used as sampling points. All encountered trees species within the PCQ were identified and recorded. The result revealed that there are 32 woody plant species from 20 families. The dominant family was Caesalpinodae. In woodland the common species was Prosopix africana (12.14 %) while in the riparian vegetation Syzygium guineense (24.12 %) was the dominant woody plant species. The hilly vegetation recorded Berlinia auriculata (45 31 %) as the dominant species. The riparian vegetation had the highest density per hectare (617 trees/ha) followed by the hilly vegetation (13 trees/ha) and the woodland (2 trees/ha). The species diversity index showed that the woodland is slightly above the riparian by 0.2, while the hilly has the lowest diversity index (0.3). Only two plants were utilized by animals; Oryza sativa and Manihot esculenta. The difference in species composition is attributed to human activities. It is therefore strongly recommended that Silvicultural management practices should be intensified at the study area.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Response of Storage Fungi of Onion (Allium cepa) to selected Botanicals 2023-03-23T06:54:28+01:00 F.

Extracts of many plants are effective for control of fungal pathogens. So far, little information is available on the use of several plant extracts in controlling rot of onion bulbs caused by plant pathogens during storage. Therefore, this study aimed to isolate and identify rot-causing fungi of onion sold in Umuahia and their response to selected botanicals. Infected onion (White and red) n= 12, were sourced from Orie-Ugba and Ubani markets for isolation and identification using standard techniques. Also, response of Rhizopus sp, Fusarium sp and Aspergillus niger to aqueous extracts of clove and African nutmeg seeds were evaluated in-vitro and in-vivo (before and after treatment). Experiments were laid out in CRD in triplicates. Clove (Syzgium aromaticum) and African nutmeg (Monodora myristica) extracts respectively reduced Aspergillus niger (71.55, 42.96%) Fusarium sp (63.82,58.28%), and Rhizopus sp (67.79,26.06%) in-vitro. Clove applied before and after fungi inoculation respectively reduced growth of Aspergillus niger (69.64,60.71%), Rhizopus sp, (88.89,84.44%) and Fusarium sp (70.00, 58.89%) in-vivo. Growths of Aspergillus niger (69.64,69.64%), Rhizopus sp, (50.00,53.33%) and Fusarium sp (82.22,58.89%) were reduced by African nutmeg before and after treatment respectively. Extracts showed promising prospect for control of Fusarium sp, Aspergillus niger and Rhizopus sp growth in both trials and could be explored for management of post-harvest onion rots at pre and post stages of fungal infection.</em></p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Nematodes Associated with Citrullus lanatus in Kwara State, Nigeria 2023-03-23T06:57:43+01:00 O.

The design used was a completely randomized design (CRD) with three replications. The test plant extracts of different concentrations were added into petri dishes containing molten sterilized Sabouraud Dextrose Agar (SDA) and swayed gently on the Laboratory bench to allow even mixing. These were allowed to gel. Then nine-millimeter discs of a seven-day pure culture of Aspergillus flavus were aseptically placed on the center of the petri dishes containing the SDA-extract mixture. Record on radial inhibition effect of the test plant extract was kept for further analysis. Analysis of variance (ANOVA) was conducted on data on radial inhibition of test fungus. Results showed that Aspergillus niger, Aspergillus flavus and Aspergillus terreus were isolated from incubated African yam bean seeds. Results also showed that Carica papaya leaf extract used was very effective and the higher the concentrations of extract, the more effective in the inhibition of radial growth of the test fungal organism. It could therefore be recommended that farmers should always conduct viability test on procured seeds for planting. That farmers should rather use plant extract such as was used in this investigation if stabilized in controlling seed borne fungal pathogens of African yam bean seeds than synthetic fungicides.</em></p> <p>&nbsp;</p> <p>&nbsp;</p> 2023-03-23T00:00:00+01:00 Copyright (c) 2023 Evaluation of the Effect of Diet Containing Cinnamon and Red Pepper on Serum Biochemistry and Hematological Indices of Broiler 2023-03-23T07:07:41+01:00 L.

The sector needs to play its role in contributing to the food, nutrition and livelihood security of the people of Nigeria. Developing climate-smart approaches with a gender-balanced perspective is key to ensuring success in mitigation of its effects. For this to be possible, the challenges limiting the growth of the sector must be addressed by the policy makers, researchers, and other stakeholders. Women need to be given the right space to play their roles in the fisheries and aquaculture sector just like the men. This will require some institutional framework and support on the part of the government to be achieved.

Climate change and its effects on livestock production as well as the vulnerable farmers and gender disparity on men’s and women’s need and priorities in adapting to climate change irrespective CSA initiatives were highlighted. Climate-smart livestock production strategies as well as CSA practices for improving livestock production and the roles of roles of agricultural extension in strengthening livestock systems through climate-smart and gender sensitive approaches were equally emphasized. There is therefore, the need for capacity building of both genders on the strategies to tackle the issues of climate change for enhanced production to achieve sustainable food production.

Factors influencing the level of participation of Irish potato farmers in WAYE programme in Plateau State are, marital status (3.72, P&lt;0.01), sex (2.25, P&lt;0.05), years of Irish potatoes production (9.85, P&lt;0.01), household size (10.92, P&lt; 0.01), awareness of WAYE programme (4.93, P&lt; 0.01), a unit increase in these factors will subsequently influence the level of participation of Irish potato farmers in WAYE programme. The mean crops output of WAYE programme participants (537,807.1kg) was significantly higher than non-participants (165,571.43kg). The difference in the mean crops output levels was largely attributed to participation in WAYE programme. The calculated Z-test value (14.74) for crops output and income (22.93) was significant at 1% probability level. It was therefore recommended that WAYE programme be extended to other farming communities in Plateau State, so as to accelerate the poverty alleviation among women farmers in the State.</p> <p>&nbsp;</p> 2023-03-24T00:00:00+01:00 Copyright (c) 2023 Assessment of two Biofertilizers under two Crop Combination on Microbial Population and Plant Growth in South Eastern Nigeria 2023-05-21T17:23:39+01:00 C.U.

The experiments were conducted in pots with dimension of 17cm × 19cm in length and depth. The bottoms portions of the pots were uniformly perforated for proper aeration. Ten seeds were planted after which they were thinned down to 8 seedlings 10 DAP, later, the remaining 2seedlings were harvested 60 DAP to evaluate the biomass production in each stage respectively. Significant biomass and soil microbial population increase due to biofertilizer use were observed in all experimental treatments. The biofertilizer effect on Moringa and tomato growth did not significantly differ. Nevertheless, positive effects of the biofertilizers occurred on the biological properties. However, the trends in these results seem to indicate that biofertilizers might be most helpful in rainfed environments. However, for use in these target environments, biofertilizers need to be evaluated under conditions with abiotic stresses typical of such systems such as drought, soil acidity, or low soil fertility.</p> <p>&nbsp;</p> 2023-03-24T00:00:00+01:00 Copyright (c) 2023
