Abstract
In this study, we used a household level survey to assess choices of varieties and demand for improved cassava varieties. A multivariate probit model was used to examine the determinants of choice decisions of the farmers for different varieties preventing potential endogeneity and measurement error. A Linearized Almost Ideal Demand System (LA/AIDS) model was used to analyze the demand system for improved cassava varieties. The results of the (LA/AIDS) model indicated farmers were very price sensitive to changes in improved stem prices and incomes. We suggest that intervention program that will improve the purchasing power of the farmers should be targeted towards the smallholder cassava farmers to accelerate adoption of improved cassava varieties.

We assessed the nature of the demand for improved cassava stems in Nigeria
Summary
About 177,948 million tonnes of cassava were produced in Africa (Otekunrin and Sawicka (2019). Nigeria is regarded as the world’s largest producer of cassava with about 20.4 percent of the world export in year 2017 (Otekunrin and Sawicka, 2019). IITA rapidly developed varieties that were resistant to this virus, and these were introduced through a fast‐track approach of releasing new varieties, and a massive approach of reaching out to farmers (HarvestPlus, 2010). From 2006-2014, not less than twenty improved cassava varieties were leased giving an optimum yield to the farmers (Kolapo et al, 2020b)
