%O This study was carried out with Funds provided to the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) by the United States Agency for International Development (USAID) within the framework of the implementation of a regional project dubbed “Increasing Groundnut Productivity of Smallholder Farmers in Mali, Ghana and Nigeria”. Results of the study have been used for securing the Master of Science (M.Sc.) Degree in Agricultural Economics by the second author in the Department of Agricultural Economics of the Bayero University of Kano (BUK). The authors are grateful to all Project Desk Officers and Extension Agents of the ADPs) of the States concerned and representatives of households who provided responses to the survey team. %K Improved groundnut technologies, adoption, Northwestern Nigeria, Nigeria, Groundnut technologies, adoption %A M B Vabi %A S A Sadiq %A A Mustaph %A A Suleiman %A H D Affognon %A H A Ajeigbe %A A A Kasim %I International Scholars Journals %V 6 %L icrisat11081 %J African Journal of Agriculture %N 1 %P 1-16 %D 2019 %X The most recent groundnut varieties registered and released in Nigeria are SAMNUT 24, SAMUT 25 and SAMNUT 26. Using appropriate sampling procedures, a total of 224 representatives of farm-families were interviewed with 112 from administrative units where a development project is being implemented (PLGA), and 112 from administrative units where project interventions are absent (NPLGA). Results of the study reveal that improved groundnut varieties are becoming part of a multitude of groundnut varieties being cultivated by farmers in PLGA and NPLGAs. Amongst the improved groundnut varieties, SAMNUT 24 was being planted by 39% and 28% of households in PLGA and NPLGA, respectively. Similarly, amongst the varieties described as local, Ex-dakar is grown by 31% and 35% of households in PLGA and NPLGA, respectively. Five underlying factors were found to drive adoption decisions: farming experience, age, education, access to (improved seeds and extension services) and household size. Beyond the combined use of seeds of improved groundnut varieties and accompanying management practices, using the right combination of inputs to optimize financial gains remains a challenge to the households involved in the study. %T Patterns and drivers of the adoption of improved groundnut technologies in North-western Nigeria
