The study assessed the effects of Fadama lll on rural rice farmers in Yola-North LGA of Adamawa State, Nigeria. The objectives are to; described the socio-economic characteristics of the respondents, Estimate the cost and returns of Fadama and non-Fadama participants, to assess the change in output and to assess the change in income among the respondents. One hundred and twenty four (124) respondents were selected from beneficiaries and non-beneficiaries of the project through multi stage and purposive random sampling. Structured questionnaire were used to obtained data on the Socio-economic characteristics, Cost and Returns, Change in output and Change in income. The data were analysed using Descriptive and inferential statistics. The findings reveals that majority of the respondents were males (71.4%) and married (69.6}.These categories of respondents are in their productive ages (30 – 39 and 40 – 49) capable of engaging in farming activities and they account for 64 % whom are the majority. Revenue generated by the beneficiaries is higher than that of the non-beneficiaries as revealed by the Gross margin analysis, likewise the T-test showed the mean Income of the beneficiaries was higher compared to that of the non-beneficiaries even though the difference was not significant at p=0.05 .Despite the fact that the project had made little impact on the living conditions of the beneficiaries, it is recommended that it should be continue in order to ensure sustained income and revenue generation.

This study was carried to analyze the technical efficiency of cowpea marketing in Mubi North. Both primary and secondary data were used. 120 questionnaires were administered only 74 were respondent to. The results were analyzed using data envelopment analysis (DEA) which involves constant return to scale (CCR) model and variable return to scale (BCC) model.  The result shows that majority of the respondents are male. And that majority about 41% of them fall within the age of 31-40 years. The Marital status of the respondents showed that majority about 73% of the marketers are married. And the result on Household size of the respondents revealed that majority about 83% of the marketers’ household size falls within 2-11 members. Level of education of the marketers showed that about 69% of them received low level formal education and majority with 2 to 17-years’ experience on cowpea marketing. majority of them about 69% are formally educated in one form or the other while 31% are informally educated. Income level of the respondents showed that more than half 54% of the marketers earned an income of 15,000 and below while 46% earned above 15,000. Results on the marketing experience of the respondents showed that majority of them have 2-6 years of experience. The results show that about 70% of the marketers belong to a cooperative while 30% do not. The study also delved into the challenges experienced by cowpea marketers. Based on the envelopment analysis result of cowpea marketing efficiency it revealed that socio-economic characteristics of the respondents has positive influence on the cowpea marketing efficiency. It provided suggestions for the Government and NGOS to implement that will curb these challenges.

This paper examines the parametric efficiency analysis of rubber production in Malaysia using Stochastic Frontier Analysis (SFA). The 3 different sample sizes used were 307, 206 and 101 for all-age, matured-age and old-age categories respectively. The results of the study reveals that the mean values of the rubber yield under all-age category was 3,638.28kg/ha while that of the matured-age and old-age categories 4,611.34kg/ha and 1,653.61kg/ha respectively. The Maximum likelihood estimates (MLE) results revealed that 5 independent variables were significant under all-age and matured-age categories while the old-age category has all the independent variables significant. With regards to elasticity of production for rubber task, 1% increase in number of rubber tree/ha leads to an increase in 0.76, 0.70 and 0.61 per cents in all-age, matured-age and old-age crop categories respectively. The coefficients values of the sigma squared for the all-age, matured-age and old-age were 0.14, 0.26 and 0.03 respectively, while the gamma values for the respective crops age categories stood at 1.00, 1.00 and 0.5. The coefficients values of all-age crops category showed that 3 variables were statistically significant at 1% level of significance. 2 variables were having negative coefficients while the remaining 1 had positive coefficient. The mean technical efficiency scores for all-age, matured-age and old-age crops categories were found to be respectively 0.70, 0.77 and 0.72. None of the crops age categories have farms on the frontier. The study concludes that Race and marital status were found to be very critical in determining efficiency of all-age crop category. Also, the matured-age crops are better than the other two crop-age categories in terms of efficiency. Also, both the matured-age and the all-age crop categories are experiencing decreasing return to scale of the production process while the old-age category has an increasing return to scale production process. The study recommends downsizing some of the inputs especially farm size, fertilizer application rate as well as farm tools.
