Abstract

This study assesses the impacts of adoption of improved soybean varieties and agronomic practices on soybean yields and net crop incomes in Malawi using data collected from over 1200 soybean growing households. The yield and crop income effects were analyzed using stochastic dominance analysis (SDA), propensity score matching (PSM) and inverse-probability-weighted regression adjustment (IPWRA). The results from the SDA show that the cumulative distribution functions for soybean yield and net crop income for the adopters of improved soybean varieties and agronomic practices significantly dominate those of the non-adopters. This indicates if randomly chosen, there is a higher probability that the adopters will on average have higher soybean yield and net crop income than the non-adopters. The results from the PSM and IPWRA show that adoption of improved soybean varieties and agronomic practices increase soybean yields by 193-198 kg/ha and net crop income by 24 USD/ha. This implies that adoption of improved soybean varieties and agronomic practices increases soybean yields by 20% and net crop income by 19%. The results point to the need for further scaling up of seeds of improved soybean varieties and complementary agronomic practices for greater adoption and impact on the livelihoods of smallholder farmers in Malawi.
