The household urban solid wastes were mixed with poultry manure and <em>Mucuna pruriens </em>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 (&gt;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/ of zinc, 27.1±1.01 - 76.6±1.03 mg/ of copper, 2.07±0.33 - 9.19±0.22 mg/ of lead, 4.13±0.16 - 11.05±0.36 mg/ of nickel and 0.79±0.02 - 2.15±0.03 mg/ 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.</p> <p>Int. J. Agril. Res. Innov.

The experiment was carried out in randomized complete block design with three replications. Eleven improved lentil varieties were used for this study. The varieties included in the study were Teshale, Alemaya, Alemtena, Assano, Gudo, EL-142, R-186, Ada’a, Derso, Chalew and Chekol. The parameters studied in this experiment were days to flowering and maturity, plant height, number of pods plant-1, number of seeds pod-1, thousand seeds weight and grain yield. The analysis of the experiment showed significant (p&lt;0.05) differences among varieties for all studied parameters. The varieties Assano, Alemtena, Derso, EL-142, and Gudo were found to be high yielder with the value of 1.71, 1.59, 1.39, 1.36 and 1.31 ton ha-1, respectively. In addition, farmers were invited to evaluate the performance of the tested varieties under field condition. Eventually, the farmers selected Assano and Alemtena as the most preferred varieties. Therefore, these varieties can be suggested to use for wider production in the study area. The involvement of farmers in variety selection processes may increases the adoption of new variety in the area.</p> <p>Int. J. Agril. Res. Innov.

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.</p> <p>Int.

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.</p> <p>Int.

In IPMP, sorting, grading and washing of eggplants were done, and packed them in plastic crates with or without modified atmosphere packaging (MAP). Traditional postharvest management practices (TPMP) existed in the value chain was used as control treatment. IPMP including the use of plastic crate with MAP reduced weight losses by 26.7 and 38.0% at wholesale and 2-days display at retail outlets. The total postharvest loss of eggplant handled with TPMP including packed in jute sack was 40.0%, whereas it was only 4.5% when followed IPMP. The reduction of postharvest losses of eggplants handled with IPMP amounted to 88.7%, and 100.0% fruit could be sold at retail outlets. The additional weekly gross income of a small trader by selling 1000 kg eggplant handled with IPMP comprising the plastic crates with MA packaging would be BDT 17,190 (USD 207).</p> <p>Int. J. Agril.

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.</p> <p>Int.

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&lt;0.05), income (p&lt;0.05) and years of schooling (p&lt;0.05) show significant and positive effects on access to credit. On the other hand, gender (p&lt;0.05), distance to credit source (p&lt;0.1) and interest rate (p&lt;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.</p> <p>Int. J. Agril. Res. Innov.

To feed the growing population, increasing the production of food through growing more crop types in the same field as an intercropping is the right strategy. The current study was aimed at evaluating the effect of sorghum-legume intercropping and its residual effect on yield of sorghum. The land equivalent ratio was calculated for sorghum intercropped with pigeon pea and cowpea. Intercropping sorghum with pigeon pea and cowpea increases the land productivity as its Land Equivalent Ratio is greater than 1. In both cases, the land equivalent ratio is greater than 1 indicating the benefits of intercropping. The residual effect of sorghum intercrop with legumes was evaluated on the yield of sorghum. Although there was no statistically significance differences on yield and yield component of sorghum, sorghum planted on the plot of pigeon pea and cowpea sole has 44.6% and 27.8% yield advantage relative to sorghum alone respectively. Planting sorghum under sorghum-cowpea intercropped condition increase the yield of sorghum by 41.8%. The result also shows 74.0% sorghum yield change was observed when planted after intercropped condition of sorghum with pigeon pea. The productivity of sorghum also increases when planted on the plot of sole legume. The current finding in general shows that legume crops contributed to the yield of sorghum either intercropped with legume or grown up using residual contribution of legumes after a year. Therefore, for maximum sorghum production farmers in the area should plant either as intercrop or after residual effect of legumes.</p> <p>Int. J. Agril. Res. Innov.

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.</p> <p>Int. J. Agril. Res.

Fish population density was 80 fish per decimal under treatment-I, 160 fish per decimal under treatment-II and 320 fish per decimal under treatment-III. In the ponds under three treatments supplementary feed was not used. The average initial length and weight of the fry of tilapia was 4.48 cm and 0.067 g, respectively. The ponds were fertilized fortnightly with urea and TSP at the rates of 60 g, and 90 g per decimal, respectively. Mean survival rates of fish under treatment-I, treatment-II and treatment-III were 91.12%, 82.82% and 66.23%, respectively. The specific growth rates (SGR, % per day) of fish under treatment-I, treatment-II and treatment-III were 5.49%, 4.95% and 4.61%, respectively. The calculated net fish production of the ponds under treatment-I was 2.65 ton ha-1 yr-1 and that of the ponds under treatment-II was 2.55 ton ha-1 yr-1 and that of the ponds under treatment-III was 2.68 ton ha-1 yr-1. The net fish production under treatment-I and treatment-III were 2.65 ton ha-1 yr-1 and 2.68 ton ha-1 yr-1 higher than that of treatment-II, taking net fish production under treatment-I for 100%. According to survival rates and specific growth rates treatment-I is the best. So, the population density of 80 fish per decimal (under treatment-I) might be considered the best among the three treatments.</p> <p>Int. J. Agril. Res. Innov.
