Household survey data of 2,732 households was used to assess the drivers of exposure, adoption and impacts of modern groundnut varieties released less than 20 years ago on household poverty and food security. Results showed that adoption is largely explained by knowledge of modern varieties known, age and education of household head, the total work force and household size. This is consistent with many other adoption studies. In addition, access to seed was significant while and access to markets was not. Results estimated the adoption of modern groundnut varieties by 22% of farmers accounting for 13% of the groundnut area planted. Using the treatment effect estimation framework, the potential adoption rate for groundnut is estimated to 78% leading to an adoption gap of 56%, implying that there are potential to increase adoption of modern groundnut varieties based on awareness or promotion. The propensity score matching and other econometric methods indicate that the effects of modern groundnut varieties on yield are estimated between 155.05 kg per ha and 202 kg/ha between adopters and matched non-adopters. The estimated impacts of adoption on the score of consumption and coping strategy index (proxy for food security) are significantly different between adopters and matched non-adopters. There are impacts on food security and no proven impacts on poverty. Investment on promotion and seed projects are essential to boost uptake of groundnut varieties in Nigeria and generate more impacts.
