This study investigates gender differences in allocative efficiency among Bambara groundnut farmers in Northeast Nigeria.The objectives include estimating the economic efficiency of Bambara groundnut farmers, comparing the economic efficiency of Bambara groundnut farmers, and analyzing the determinants of economic efficiency of Bambara groundnut in Northeast, Nigeria. The study adopted a survey design. A multistage sampling technique was used to select a total of 360 male and 360 female smallholder Bambara groundnut farmers from three selected states including Adamawa, Bauchi, and Taraba States. Primary data was collected from the respondents using a well-structured questionnaire. Data were analysed using descriptive statistics and econometric techniques, including the, Cobb-Douglas stochastic frontier cost function model, independent z-test, and censored Tobit regression model. Findings reveal that female farmers demonstrated superior allocative efficiency compared to their male counterparts across all states and the wider Northeast Region. Determinants of allocative inefficiency varied by gender. For male farmers, key factors included age, education, farming experience, extension visits, cooperative membership, credit obtained, land ownership, and training in Bambara farming. For female farmers, significant determinants were age, household size, farming experience, extension visits, cooperative membership, distance to farm, security challenges, and off-farm income. These findings suggest the need for gender-responsive policies aimed at improving allocative efficiency, particularly through enhanced access to credit, extension services, cooperative networks, and security interventions.</p> Osayi C.P Nnamerenwa, G.C Bulus, G Copyright (c) 2025 IPHO-Journal of Advance Research in Agriculture and Environmental Science https://creativecommons.org/licenses/by-nc-sa/4.0 2025-08-15 2025-08-15 3 08 01 10 10.5281/zenodo.16881279 https://www.iphopen.org/index.php/aes/article/view/319 <p>This study assessed the factors influencing job performance of Agricultural Development Program (ADP)extension staff in Taraba State, Nigeria. The specific objectives were to; describe the socio-economic characteristics of the respondents, assess the agricultural extension staff’ level of job performance, determine the influences of socioeconomic characteristics of extension staff on their job performance in the study area.A multistage sampling technique was employed to select 200 respondents, and primary data were obtained through structured questionnaires. Descriptive statistics and OLS regression were employed for the analysis.The findings showed that 41.0% of the respondents were aged 41–50 years, with a mean age of 44 years.Males accountedfor 54.0%, and 67.0% were married. Educationally, 68.5% held university degrees, the mean years of experience was approximately 11 years and a mean household size of approximately 5 people.Likert scale results showed a high level of job performance in the study area. The regression analysis revealed that age, marital status and grade level were significant 1% and had positive influence on job performance, household size was significant at 1% and had negative influence on job performance and Household size was significant at 5% and had positive influence on job performance. The study concludes that both individual and institutional factors significantly influenced extension staff performance and recommends tailored interventions to improve capacity, mobility, and motivation for more effective extension delivery.</p> Eki Anagu, S.
