Using composting technology, the biodegradable fraction of solid wastes collected from Agbalepedogan district in Lomé (Togo) was transformed into composts with no phytotoxicity suitable for use in agriculture. The household urban solid wastes were mixed with poultry manure and Mucuna pruriens leaves in appropriate percentages and transformed into composts. The composting process was monitored by temperature, pH and C/N ratio controlling. The composts quality was appreciated by phytotoxicity test, particle size distribution, contents of nitrogen, phosphorus, potassium, organic matter and trace elements. The results showed that composts particle size distribution presented four fractions (>10 mm, 5-10 mm, 2-5 mm and ≤2 mm) whose average percentages are respectively 9.04±0.2%; 10.71±0.2%; 12.68±0.4% and 67.53±0.6%, respectively. Composts produced contained 1.02±0.1% - 2.72±0.2% of nitrogen, 1.35±0.3% - 2.70±0.4% of phosphorus, 1.31±0.2% - 1.72±0.3% of potassium and 23.50±0.4% - 37.75±0.5% of organic matter. The pH in final composts were between 8.50±0.2 and 9.00±0.3 while C/N ratio varying from 8.06±0.2 to 13.13±0.2. The concentrations of some heavy metals in final products were 79.8±1.7 - 140.2±1.6 mg/kg.dm of zinc, 27.1±1.01 - 76.6±1.03 mg/kg.dm of copper, 2.07±0.33 - 9.19±0.22 mg/kg.dm of lead, 4.13±0.16 - 11.05±0.36 mg/kg.dm of nickel and 0.79±0.02 - 2.15±0.03 mg/kg.dm of cadmium. These concentrations were lower than the limited value for heavy metals prescribed by French and US EPA regulation for organic and organic-mineral fertilizers.

Smallholder potato producers in Jeldu district produce potato for both home consumption and market. Adoption of improved varieties is suggested to improve and diversify farmers’ household income. This study intents to identify factors determining adoption and intensity of adoption of improved potato varieties in Jeldu district of West Shewa zone, Oromia region, Ethiopia. Both primary and secondary data were used. The primary data were collected from 140 sample households’ selected using two-stage random sampling techniques. Descriptive statics and double hurdle econometric model were used to analyze the data. Results indicate that sex of the household head, access to extension services, livestock ownership and farmers’ perception about the technology positively and significantly determined adoption of improved varieties in the district. In contrast, distance from the nearest market affected adoption of improved potato varieties negatively and significantly. Intensity of adoption is measured by the area of land allocated for improved potato varieties by farmers. The truncated result identified improved varieties yield perception, family size, livestock ownership and membership to agricultural cooperative influenced intensity of improved potato varieties adoption positively and significantly. Strengthening extension services to enhance farmers’ awareness about improved potato varieties infrastructure development, family planning, asset ownership and facilitating membership to cooperatives are recommended.

The study examined the adoption of soybean products among women in Onitsha North Local Government Area of Anambra State, Nigeria. Specifically, it described the socioeconomic characteristics of the respondents, identified the type of soybean products available in the area, determined the source of information of the soybean products, ascertained the level of adoption of soybean products and identified the major constraints to the adoption of soybean products in the area. Purposive and simple random methods were used to select 50 respondents. Data were collected using structured questionnaire and personal interview and analyzed using descriptive statistics such as percentage, frequency distribution and mean scores. Findings show that 91.0% of the respondents were within the age range of 30-49 years, while the mean age of the farmers was 45.43 years. Extension agents (90.0%) and friends/relatives (80.0%) were the major source of information. Based on the level of adoption of soybean products, the farmers’ adopted only five soybean products, which included soymilk, soybean cake, soybean oil, soybean nut and soy flour. The major constraints against adoption of soybean product were poor extension service to assist farmers (¯x=3.7), lack of awareness of the soybean products (¯x=3.3) and lack of capital (¯x=3.3). In line with the findings, the study therefore recommends that extension agent needs to re-package and dynamically disseminate information, educate and re-educate farmers on several health benefit of soybean use in order to upgrade farmers’ awareness and subsequently their adoption.

A rapid and non-destructive assessment of quality parameters in tomatoes was evaluated using a portable differential absorbance (DA) meter in order to accurately establish optimum harvest maturity. A commercial tomato variety cv. ‘BARI Tomato-8’ grown in the summer season of Bangladesh was used in this study. Different quality parameters including fruit skin colour, tissue firmness, chlorophyll contents, ascorbic acid, total soluble solids (TSS), titratable acidity and pH of tomatoes were determined using standard reference methods. Correlation analysis was performed to determine the relationship between the difference in absorbance index (IDA) and fruit quality parameters. The correlation coefficients showed good ability in estimating the hue angle, chlorophyll contents, titratable acidity and firmness of tomatoes showing ‘r’ values of 0.93, 0.91, 0.91 and 0.92-0.94, respectively. However, the changes of ascorbic acid contents and TSS of tomatoes did not follow the linear model during fruit maturation. Thus, the DA meter could most accurately predict the major quality attributes and may be used as an efficient technique for in-plant non-destructive assessment of tomato fruit qualities.

This study investigated the determinants of access to credit among cocoa farmers in Osun state, Nigeria. Specifically, the study described the socio-economic characteristics of cocoa farmers in the study area, examined the factors affecting access to credit by cocoa farmers in the study area; and identified the constraints faced by cocoa farmers in credit acquisition. The study was conducted in Osun state, south-western Nigeria. A multi-stage sampling procedure was used for selecting respondents for this study. A total number of 180 farmers were selected for the study. Data were analyzed using Descriptive statistics and logit Regression. The results for the entire respondents showed average values of 46 years for age, 25 years for year of experience, 8 persons for household size, and about 88% of the respondents have formal education. Farm size (p<0.05), income (p<0.05) and years of schooling (p<0.05) show significant and positive effects on access to credit. On the other hand, gender (p<0.05), distance to credit source (p<0.1) and interest rate (p<0.01) are significant but have negative effects on access to credit by cocoa farmers in the study area. Majority (85.6%) of the cocoa farmers acknowledged lack of collateral security as a constraint in credit acquisition, while about 71.1 % acknowledged that high interest rate was a factor hindering credit acquisition. Other factors are acknowledged in the following order: Bureaucratic procedures 60.6%, lack of information about available credit sources 45%, mode of repayment 40%, no credit association 31.1% and non- membership of farmers’-based organization had 23.3%. Following the findings of the study, government, non-governmental agencies and financial institutions should provide cocoa farmers with adequate access to credit facilities and soft loans with low interest and without collateral security. In addition, cocoa farmers should be educated on the acquisition of credit.

This study was conducted to analyze the profitability of banana farming in some selected areas of Tangail district of Bangladesh during 2015. A total of 60 samples (16 small, 19 medium and 25 large farmers) were directly interviewed using a structured questionnaire for achieving the purpose. Apart from the descriptive analysis of the socio-economic variables of the selected respondents, the benefit-cost and functional profitability analysis of banana farming were also performed. The Cobb-Douglas production function was chosen to determine the effects of various inputs on the profitability of banana. The finding of cost-benefit analysis reveals that banana farming is a profitable activity in Bangladesh as the estimated cost of production was lower than the return in the selected study areas. However, the profitability differs among different farmers’ group and large farmers are more profitable in banana farming than small and medium farmers. In addition, the functional analysis identifies four inputs such as the cost of human labor, manure, fertilizer and irrigation as the significant determinants of profitability of banana farming in the study area. In this study, resource use efficiency was also measured to show the efficient resource allocation to attain the goal of profit maximization which showed that human labor, seedling, manure, fertilizer, insecticides, irrigation and bamboo has inefficient use of the resources, and farmers should limit the use of these inputs. The researcher suggested some recommendations to improve the present production situation so that banana farming could be more viable and attractive commercial enterprise.
