    Market potentials for selected organic leafy vegetables
    (International journal of vegetable science, 2015) Adenegan, K.O.; Fatai, R. A.
    "Increased consumer awareness has raised concerns over food safety and production methods. In Nigeria, consumption of organic produce is low. This study assessed consumer willingness to pay for selected organic leafy vegetables. Data from 129 respondents were obtained using a simple random sampling technique. Conjoint analysis and contingent valuation were used to analyze willingness to pay and determinants of willingness to pay. Contingent valuation indicated that 84.5%, 76%, and 62.8% of the respondents were willing to pay extra for Amaranthus cruentus L., Celosia argentia L., and Cochorus olitorius L., respectively. Average willingness to pay a price premium was 46%, 42.4%, and 35.8% for A. cruentus, C. argentia, and C. olitorius, respectively. Conjoint analysis indicated that quality was the most valued attribute of leafy vegetables with relative importance of 42.2%. Income, health status, and work experience were key determinants of willingness to pay; all increasing the likelihood of willingness to pay. Income was significant with marginal effects of 0.005 and 0.006 for A. cruentus and C. olitorius, respectively. Health status was significant with marginal effects of 0.366 and 0.225 for A. cruentus and C. olitorius, respectively. Work experience was significant for all species. There is strong market potential for organic leafy vegetables, especially if quality is high and prices are reasonable. "

    Scale efficiency and determinants of productivity of new rice for Africa (nerica) farmers in Kaduna State, Nigeria
    (Agrosearch, 2014) Nosiru, O.M.O.; Rahji, M.A.Y.; Ikpi, A.E.; Adenegan, K.O.
    Rice productivity is low in Nigeria, and NERICA was introduced by West Africa Rice Development Agency (WARDA) to solve this problem. This study focused on NERICA productivity and efficiency in Kaduna State. A three-stage sampling technique was used with Kaduna State being purposively selected. Igabi and Soba Local Government Areas (LGAs) were randomly selected. Five villages were randomly selected from each LGA, with a total of 129 NERICA farmers selected and used for the analysis. There were technical and managerial inefficiencies among the farmers. NERICA production is characterized by increasing returns to scale with a value of 1.4954. The farmers were cost inefficient, hence there was room for improvement in NERICA production in the study area. The average productivity (AP) was 26.30. The average marginal productivity (MP) is 9.213. The average total factor productivity (TFP) is 12.87. Farmer’s age and access to credit had negative influence on both AP and MP. Extension contact and adoption of NERICA technology positively influenced the AP and MP. Farmer’s age had negative influence on total factor productivity. Formal education, farming experience, extension contact, farm commercialization and adoption of NERICA technology had positive influence on the total factor productivity of the NERICA farmers. Improvements in the supply of NERICA seed, extension services and level of farm commercialization are recommended.
