Item Value Chain and Competitiveness of Plantain in Southwestern Nigeria(2015) Adeoye, I. B.Nigeria ranks fifth in world plantain production but has low export volume. The low export may be a result of activities along its value chain. However there is little information on the number of employment generated, comparative advantage, competitiveness and effects of policies on plantain. Therefore, the competitiveness of plantain along the value chain in southwestern Nigeria was investigated. A three stage sampling procedure was used. The ten high plantain producing Local Government Areas (LGA) were selected in southwestern Nigeria. In each LG, two plantain producing villages were randomly selected. Producers (260) and 100 processors were randomly selected based on probability proportionate to size of villages. One hundred and forty four marketers were also randomly selected in the geopolitical zone. Structured questionnaire was used to collect information on number of job generated, cropping systems, quantity of input, output and their prices on each stage (production, farm gate and market arena assembling, processing, in-situ and transit wholesaling and retailing) of the chain. Secondary data on port charges, import/export tariffs and exchange rates were sourced from Nigeria Port Authority and trade statistics. Data were analysed using descriptive statistics, policy analysis matrix, sensitivity and partial equilibrium analyses. Major stages in plantain value chain were input supply, production, assembling, processing, wholesaling and retailing. Employment generated was 314 people/tonne with highest number (33.8%) in processing stages. Plantain/cocoa represented the highest cropping system (37.7%) while plantain/cassava (13.1%) was the least. Highest private and social profits of ₦514,547/ha and ₦1,593,611/ha were obtained in plantain/cocoyam at production stage respectively. Private Cost Ratio (PCR) ranged from 0.27 to 0.36 while Social Cost Benefit (SCB) ratio was 0.21 to 0.26. Profitability Coefficient (PC) of 0.20 to 0.32, Effective Protection Coefficient (EPC) of 0.26 to 0.37, and Subsidy Ratio to Producers (SRP) of -0.52 to - 0.62 were recorded at market price at the production stage. Plantain chips and flour had private profit of ₦426,339 and ₦408,701 and social profit of ₦764,793 and ₦561,969/tonne respectively at the processing stage. Both plantain chips and flour respectively had PCR of 0.15 and 0.11 and SCB of 0.34 and 0.33. Profitability coefficient of 0.73 and 0.56, EPC of 0.60 and 0.76 and SRP of -0.18 and -0.29 were obtained for plantain flour and chips respectively. Wholesalers had highest private profit of ₦36,800/tonne while farm gate assemblers had highest social profit of ₦137,812/tone at the marketing stage. The PC of 0.11 to 0.39, EPC of 0.12 to 0.41 and SRP of -0.24 to - 0.66 indicated lack of protection at the marketing stage. Aggregated value chain of the cropping systems had PCR of 0.18 to 0.35 and SCB of 0.30 to 0.37. Private profit of the producers respectively increased by 24.5% and 49.3% with 20.0% and 40.0% increase in yield levels. Net social loss in production was ₦6,552/tonne while consumers gained ₦28,295/tonne in the chain. Plantain/cocoyam production system had the highest private and social profits indicating that the system was profitable to participants and the southwestern economy.Item Tomatoes, Urban and Rural Market, Price Analysis, Oyo State("International Journal of Agricultural Economics and Rural Development", 2011) Adenegan, K. O.|; Adeoye, I. B."Prices are the most readily available and often the most reliable information on developing country marketing systems. The study examined the level of market integration in tomato markets in rural and urban markets of Oyo State, Nigeria. Secondary data on tomato price spanning 2003 -2010 were sourced from Oyo State Agricultural Development Programme (OYSADEP). The data were analyzed using Augmented Dicker Fuller (ADF) test. Indices of market concentration were also used to measure the degree of market integration. Results indicated that the maximum rural price of tomato was N131.74/kg in May, 2009 while the minimum price was N43.23/kg in August, 2004. In the urban areas, the maximum price was N132.I3/kg in May, 2009 while the minimum price was N40.98tkg in September, 2004. The restilts also revealed that prices of tomato were stationary at their level. Urban tomato market does not granger cause rural tomato market (P > 0.05), while rural tomato market granger cause urban tomato market (P< 0.05). None of the markets links exhibited bi -directional granger causality or simultaneous feedback relationship. The Index of market connection (IMC) indicates that the markets exhibit low short run market integration. It is recommended that there should be efficient flow of information, good access road and infrastructural development to improve market performance."Item Fruit consumption among university of Ibadan students, Nigeria(ARPN Journal of Agricultural and Biological Science, 2011) Adenegan K, 0.; Adeoye, I. B.Fruit consumption among undergraduate students was assessed in Ibadan, Oyo State, Southwest. Nigeria, The objectives of the study were to determine the proportion of students' income spent on fresh fruits and processed fruits; determine the level of acceptability of processed fruits by students and the factors affecting the consumption fresh and processed fruits, One hundred students were selected for the study using random sampling technique and data collected using well structured questionnaires, Data obtained was subjected to descriptive and regression analysis, The result of the study show that out of N6487 ,09 earned by students on the average, 4,58%, 4.4% and 9,29% of it were spent on fresh, processed and both kinds of fruits respectively. Majority of students made their choice on fruit consumption based on the prices in the market. Also, more than 60% of the respondents preferred the fresh fruits to processed fruits, Students income and taste were significant determinants of the amount spent on fresh fruits by students (P
