Soybean (Glycine max L. Merril) is one of the most nutritionally valuable legumes in Africa. However, spent automobile engine oil is always disposed indiscriminately on lands and water bodies in Nigeria, which pollutes both terrestrial and aquatic ecosystems, with adverse effects on crop growth and productivity. This study investigated the effects of spent engine oil (SEO) polluted soils on growth parameters and mitotic chromosomes of soybean. Two soybean varieties (TGX-1448-2E and local) were planted in pots filled with sandy-loam soil treated with 0, 0.1, 0.4 and 0.7% v/w SEO concentrations, in 2 × 4 factorial experiment laid in a completely randomized design with six replications. Data were collected at weekly intervals for four weeks on growth parameters (plant height, number of leaves, leaf width and leaf length) and chromosomal aberration. Data were subjected to ANOVA and means separated with LSD. Among the treatments, seed germination rate was significantly higher in TGX-1448-2E (95.0 ± 0.0-96.0 ± 0.7%) than local variety (70.0 ± 0.7-71.0 ± 0.7%). Both 0.4 and 0.7% SEO caused significant (p ≤ 0.01) reductions in plant height, number of leaves, leaf length and leaf width whereas, 0.1% did not reduce growth parameters. Treatments 0.4 and 0.7% SEO caused high chromosomal aberrations in soybean as they reduced chromosome numbers (from 40.0 to 23%), cell division, mitotic index (70.0 to 20.8%) and produced 31.7% abnormal cells. Abnormalities such as bridges, laggards and chromosome stickiness occurred. This study shows that 0.4-0.7% SEO polluted soils is phytotoxic to soybeans.
大豆(Glycine max L. Merril)是非洲最有营养价值的豆类之一。然而，在尼日利亚，废弃的汽车发动机油总是被随意丢弃在土地和水体上，污染了陆地和水生生态系统，对作物生长和生产力产生了不利影响。研究了废机油污染土壤对大豆生长参数和有丝分裂染色体的影响。采用6个完全随机设计的2 × 4因子试验，将2个大豆品种(TGX-1448-2E和当地品种)种植在砂壤土中，分别处理0、0.1、0.4和0.7% v/w的SEO。每隔一周采集4周的生长参数(株高、叶数、叶宽、叶长)和染色体畸变数据。数据进行方差分析，均数用LSD分离。处理中，TGX-1448-2E的种子发芽率(95.0±0.0 ~ 96.0±0.7%)显著高于本地品种(70.0±0.7 ~ 71.0±0.7%)。0.4和0.7%的SEO处理均显著(p≤0.01)降低了株高、叶数、叶长和叶宽，而0.1%的SEO处理对生长参数无显著影响。0.4和0.7% SEO处理使大豆染色体数目从40.0%降低到23%，细胞分裂和有丝分裂指数从70.0降低到20.8%，产生了31.7%的异常细胞。出现桥接、迟滞、染色体粘连等异常。本研究表明，0.4 ~ 0.7%的SEO污染土壤对大豆具有植物毒性。

Digital seed imaging was utilized in this study to evaluate the morphometric characteristics of pigeon pea for genotype discrimination. One hundred seeds in each of the pigeon pea accession were subjected to digital imaging analysis using the WinSEEDLE™ software to differentiate the seed metric characters. Seeds were placed on a lighting hood and were automatically analyzed by the scanner and the image of the seed was recorded by the WinSEEDLE™. The procedure was repeated three times. The parameters observed were projected area, straight length, curve length, straight width, curve width, volume circle, and projected perimeter. Data collected were subjected to analysis of variance, principal component analysis and product moment correlation coefficients between the parameters were obtained. The result revealed that the pigeon pea accessions were highly variable in all the seed metric traits evaluated. Accessions NSWCC-34 and NSWCC-32 showed superiority values in most of the seed metric traits evaluated. Accessions NSWCC-32 had 28.35 mm2 , 6.99 mm, 7.37 mm, 5.23 mm and 5.28 mm in seed projected area, seed straight length, curve length, straight width and curve width, respectively while NSWCC-34 recorded 28.34 mm2 , 6.75 mm, 7.10 mm, 5.22 mm and 5.27 mm for the same evaluated traits. Most of the seed traits showed significant positive and strong association. The study, therefore, recommends that accessions NSWCC-34 and NSWCC-32 as well as those traits with high contribution to the major variation (seed projected area, seed straight length, curve length, straight width, curve width and volume circle) could be included in the seed improvement programme for improved seed quality in pigeon pea.

The study investigated gender in wholesale smoked-fish marketing in Kanji Lake Basin, Nigeria. Specifically, the study identified roles of individual actors in fish marketing, determined the profitability of fish marketing, analyzed the marketing efficiencies and estimated gaps in the fish marketing chain. A two-stage sampling procedure was used to select 60 wholesale smoked-fish marketers from 13 communities. Primary data were collected from wholesale smoke-fish marketers using an interview schedule. Data were analyzed using percentages, net profit margin and efficiency models. The result showed that the youths perform about 60% of task in activities such as sorting and grading, fish arrangement in cartons, loading and offloading and transportation to market centers. Wholesale fish marketing was profitable with a 4.45% return on investment (ROI) for the men, 3.76% ROI for the women and 2.88% ROI for the youths while Shepherd’s marketing efficiency was 24.84 for the men, 25.65 and 26.65 for the women and youths respectively. Also, there were no glaring gender gaps in value of fixed assets, revenue, gender-based employees and wage for the men, women and youths involved in the business. Therefore, it is recommended that capacity building which targets women and youths should be adopted and implemented by government and other relevant agencies in order to enable them compete equally with men in wholesale smoked-fish marketing.

The study was conducted to assess cultural practices and post-harvest handling of some selected neglected food crops (bambara nut, bread fruits and bush-mango) in South-east and South-south Nigeria. The specific objectives of the study were to; identify the cultural practices of selected neglected crops; identify the postharvest handling procedure of the selected neglected crops; identify uses of other parts of the neglected crops apart from the food storage organs and investigates the medicinal value of selected neglected crops. A purposive and snow-ball sampling procedure was used to sample 120 farmers of selected neglected crops in South-east and South-south Nigeria (Akwa-Ibom, Ebonyi and Rivers). A well-structured questionnaire was used to obtain information from the respondents and presented using percentage and mean. The result showed that the cultural and agronomic practices for the neglected crops included; nursery (66.7%), intercropping (79.2%), fertilizer application (66.7%) and weeding (100%). The farmers use the neglected crops as soup, chips, flour, and food by boiling or roasting. Processing activities done before storage include fermentation, breaking of the pod, sun drying and cleaning of the crops without water. The method of storage showed that 25% used nylon, 65% used bags and 10% used air tight container. The farmers made use of; leaves of neglected food crops for animal feeds formulation, fermented fruits for organic manure, and stems and branches for timber woods for building and construction. Also, farmers used some of the neglected tree crops for treating fever, stomach upset and diabetes. Also, it is used to boost blood level, antibiotics, pile treatment and prevention of heart failure. The study recommended that Research institutes, ADPs and other related NGOs should work in collaboration to train the farmers on modern methods of post-harvest handlings of crops in the study area. Also, policy maker should formulate policy that will encourage the production of neglected food crops in large quantity.

Crop production can be limited by soil acidity. A two-factor factorial experiment involving three levels each of ash and poultry manure (PM) was conducted to determine the effects of ash and PM on soil reaction and performance of maize in an acid soil. The ash comprised of mixture of ash from wood, cocoa husk and palm bunch. The levels of ash (0.00, 3.00, 6.00 t ha–1 ) and PM (0.00, 4.00, 8.00 t ha–1 ) were combined to obtain nine treatment combinations (control, 3.00 ash and 0.00 PM, 3.00 ash and 4.00 PM, 3.00 ash and 8.00 PM, 0.00 ash and 4.00 PM, 3.00 ash and 0.00 PM) which were replicated thrice. The experiment was laid out in a randomized complete block design. Soil samples were collected at 3, 6, 9 and 12 weeks after planting (WAP), plant height measured at 3, 5, 7, and 9 WAP while cob oven-dry weight was measured after oven-drying harvested cobs at maturity. Analysis of variance was conducted on the data collected using GenStat version 14. The highest plant height of 132.50 cm at 12 WAP and the highest oven-dry cob weight of 7.15 t ha–1 were obtained from plots treated with 6.00 and 8.00 t ha-1 of ash and PM, respectively, and these were significantly (p ≤ 0.05) different from the other treatments. The lowest exchangeable acidity of 1.33 cmol kg–1 which varied significantly (p ≤ 0.05) from the other values observed at the other plots was obtained at the plot treated with the combination of 6.00 and 4.00 t ha–1 of ash and PM, respectively at 12 WAP. The combination of ash and PM at 3.00 and 8.00 t ha–1 gave the highest pH of 6.80, and this was significantly (p ≤ 0.05) different from the other treatments. Therefore, ash and PM at varying levels of combination can simultaneously ameliorate soil acidity and improve maize performance; however, the best combination of ash and PM application which showed the potential to produce optimum effect in simultaneously ameliorating soil acidity and increasing maize performance was the combination of 6.00 tonnes of ash and 8.00 tonnes of PM.
土壤酸度会限制作物产量。采用灰和禽粪(PM)各3个水平的双因素析因试验，研究了灰和PM对酸性土壤中玉米土壤反应和生产性能的影响。这种灰烬由木材、可可壳和棕榈束的灰烬混合而成。将灰分(0.00、3.00、6.00 t ha-1)和PM(0.00、4.00、8.00 t ha-1)组合，得到对照、3.00灰分和0.00 PM、3.00灰分和4.00 PM、3.00灰分和8.00 PM、0.00灰分和4.00 PM、3.00灰分和0.00 PM 9个处理组合，重复3次。实验采用完全随机区组设计。在播种后3、6、9和12周采集土壤样品，在播种后3、5、7和9周测量株高，在收获的成熟穗轴烘干后测量烤炉干重。使用GenStat version 14对收集的数据进行方差分析。灰分和PM浓度分别为6.00和8.00 t ha-1的地块，12 WAP时株高最高，达到132.50 cm，烘干重最高，达到7.15 t ha-1，与其他处理差异显著(p≤0.05)。12 WAP时，灰分和PM浓度分别为6.00和4.00 t ha-1的处理地块的交换性酸度最低，分别为1.33 cmol kg-1，与其他地块的值差异显著(p≤0.05)。在3.00和8.00 t hm - 1处理下，灰分与PM组合处理的pH值最高，为6.80，与其他处理差异显著(p≤0.05)。因此，灰分与PM在不同水平上的组合可以同时改善土壤酸度和提高玉米生产性能;然而，在同时改善土壤酸度和提高玉米生产性能方面，灰分和PM的最佳组合是6.00吨灰分和8.00吨PM的组合。

Young people perceive agriculture as a profession of intense labour, not profitable and unable to support their livelihood compared to what white collar jobs offer. The study was on determinants of youth participation in agribusiness activities in Ikwuano Local Government Area, Abia State, Nigeria. Specifically, the study examined the socio-economic characteristics of youths in the study area; identified various agro-related enterprises participated by the youths and estimated factors that influence youth participation in agro- related enterprises. Random sampling technique was used to select 90 respondents for the study. Data were analyzed using both descriptive statistics and Probit regression model. Majority (62.42%) of the youths were male. Mean age of the respondents was 23 years. About 90% of the youths were single with diverse levels of formal education. The agribusiness enterprises mostly participated in by the youths were animal production (51.1%) and crop production (23.33%). Result of Probit regression showed that age, household size, access to land, non-farm income, empowerment were 1% respectively and sex (5%) were significant variables influencing youth participation in agribusiness activities. It was recommended that youth in the study area enhance their livelihood sources through diversifying into other agro-related enterprises such as sale of agro-inputs and agro-processing.

Cashew nut (Anacardium occidentale L) is one of the most essential and major cash crops produced in Nigeria. This research, therefore, explored the economics of cashew nuts marketing in Udi Local Government Area of Enugu State, Nigeria. Primary data were sourced from cashew nut marketers through the use of well-designed questionnaires. Sixty respondents were randomly selected from three main markets in the study area. Descriptive statistics and (OLS) multiple regression models were used to achieve the study objectives. Descriptive statistics and (OLS) multiple regression models were used to achieve the objectives. Wherefore the study identified the marketing channels, analysed the cost and returns of the enterprise, determined the socio-economic factors affecting the quantity of cashew nuts marketed, and ascertained the constraints associated with cashew nuts marketing in the study area. From the results, the market was dominated by males (65%), most of the respondents (51.7%) were between 21 and 40 years, and majority were married (81.7%). An average number of the marketers (50%) had secondary school education, while 31.7% and 18.7% had primary and higher education, respectively. Most of the marketers (63.3%) bought directly from farmers, while 26.7% purchased from wholesalers. Total revenue, gross profit, and net profit were respectively ₦651,627.00, ₦120,618.00, and ₦81,067.70, showing that the business is profitable. Respondents’ socioeconomic characteristics which significantly affected quantity of cashew nut marketed were age (p < 0.1), household size (p < 0.05), and membership to market association (p < 0.05). Major constraints were seasonality of produce, high cost of transportation, bad weather (rain), and inadequate capital. It was recommended that government should provide good road networks to ease transportation problem. The marketers should form cooperative societies to facilitate easy access to credits and other relevant resources.

This research, therefore, explored the economics of cashew nuts marketing in Udi Local Government Area of Enugu State, Nigeria. Primary data were sourced from cashew nut marketers through the use of well-designed questionnaires. Sixty respondents were randomly selected from three main markets in the study area. Descriptive statistics and (OLS) multiple regression models were used to achieve the study objectives. Descriptive statistics and (OLS) multiple regression models were used to achieve the objectives. Wherefore the study identified the marketing channels, analysed the cost and returns of the enterprise, determined the socio-economic factors affecting the quantity of cashew nuts marketed, and ascertained the constraints associated with cashew nuts marketing in the study area. From the results, the market was dominated by males (65%), most of the respondents (51.7%) were between 21 and 40 years, and majority were married (81.7%). An average number of the marketers (50%) had secondary school education, while 31.7% and 18.7% had primary and higher education, respectively. Most of the marketers (63.3%) bought directly from farmers, while 26.7% purchased from wholesalers. Total revenue, gross profit, and net profit were respectively ₦651,627.00, ₦120,618.00, and ₦81,067.70, showing that the business is profitable. Respondents’ socioeconomic characteristics which significantly affected quantity of cashew nut marketed were age (p < 0.1), household size (p < 0.05), and membership to market association (p < 0.05). Major constraints were seasonality of produce, high cost of transportation, bad weather (rain), and inadequate capital. It was recommended that government should provide good road networks to ease transportation problem. The marketers should form cooperative societies to facilitate easy access to credits and other relevant resources.

Tomato paste contains antioxidant compounds which act against free radical actions in the body and prevents oxidative damage and boost the physiological health of consumers. However, information on the phytochemicals, antioxidant activities and nutritive qualities of tomato pastes sold in Umuahia Metropolis is scarce. This work was undertaken to fill this gap on five selected commercial tomato pastes sold in Umuahia Metropolis, Abia State, Nigeria namely, Sonia (SON), Gento (GEN), Superdelicieux (SUP), Star (STA) and Clappa (CLA). The physicochemical and antioxidant activity parameters were determined by standard methods. The results showed that lycopene (4.20 mg 100g‒1 ), vitamin C (12.76 mg 100g‒1 ) and vitamin A (1.43 mg 100g‒1 ) were significantly (p < 0.05) higher in STA tomato paste. β-carotene (3.02 mg 100g‒1 ) and vitamin E (11.14 mg 100g‒1 ) were significantly (p < 0.05) higher in CLA tomato paste, while phenol was significantly (p < 0.05) higher in SUP tomato paste. The chemical composition revealed that total solid ranged from 28.91 (STA) to 31.67% (SON), reducing sugar ranged from 8.78 (SUP) to 16.16% (CLA), while titratable acidity ranged from 0.21 (SON) to 0.31% (GEN) and pH ranged from 4.27 (CLA) to 4.47 (STA), respectively. Minerals concentration for Ca ranged from 1.79 (CLA) to 2.86 mg 100g‒1 (SON), Mg from 8.57 (SON) to 13.61 mg 100g‒1 (STA), K from 7.81 (SON) to 30.44 mg 100g‒1 (STA), Na from 12.21 (STA) to 15.59 mg 100g‒1 (CLA) and Fe from 0.82 (STA) to 1.89 mg 100g‒1 (SON). Stronger antioxidant activity was observed in SON paste for 1,1- diphenyl-2-picryl (DPPH) (62.07%), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) (41%) and Ferric Reducing Antioxidant Power (FRAP) (47.88%). The results revealed that concentration of nutritive quality was specific to individual tomato paste, but SON possessed stronger antioxidant activity scavenging power than other tomato pastes. From the results of physicochemical and antioxidant activity of these tomato pastes, they may be used to boost physiological performance against degenerative diseases.

The study analyzed intensity of technology-use among palm fruits’ processors in Onicha Local Government Area in Ebonyi State, Nigeria. Specifically, the study described the intensity of technologies-use in oil palm processing in the area; ascertained the determinants of method of processing used by oil palm fruit processors and examined the constraints to oil palm fruits processing in the study area. Purposive sampling procedure was employed to select 58 respondents for the study. Data were analyzed using descriptive analysis (frequency, percentage, mean) and logit analysis. Logit analysis indicated that marital status (–6.754), cost of labor (–0.002), level of education (2.303) and annual income (0.342) were the variables that determined technology-use, while variables such as credit access and quantity of oil palm fruit were not significant. The constraints encountered in technology-use were ranked as follows high cost of palm fruits (95%), inadequate processing equipment (91.37%), difficulty in obtaining credit (86.21%), high cost of palm fruits transportation (84.48%), and inadequacy in the supply of palm fruits (76.31%). It is recommended that palm fruit processors should form a co-operative society thereby procure more equipment for sustainable palm fruits’ processing.

The purpose of the study was to assess the hydrochemical characteristics of the Kanzenze River and its suitability for irrigation use in the Akagera upper catchment in Rwanda. In this respect, 12 samples of surface collected water in four sites namely Karumuna, Muzi, Karugenge, and Nyamabuye were at a distance of 100.00 meters one to another. The Food and Agriculture Organization (FAO) standards were referred to analyze water quality parameters such as potential hydrogen (pH), electrical conductivity (EC), total dissolved solids (TDS), sodium adsorption ratio, soluble sodium percent, total hardness, magnesium adsorption ratio and Kelly index were used for the evaluation of water quality and its suitability for irrigation. Data were analyzed using descriptive analysis and principal components analysis. All parameters analyzed were within the FAO standards stipulated for irrigation. The mean pH of the water sample was 7.30; the mean TDS was 205.10 mg l‒1; mean sodium adsorption was 2.30 while the mean EC was 302.26 µS/cm which indicated that Kanzenze River is in category I of classification standard suitable for irrigation. This indicated that the Kanzenze River was suitable for irrigation.
