We analyse the effects of adoption of urea deep placement (UDP) technology on household welfare using household data collected through a randomized control trial experiment conducted among rice farming households in Kwara State, Nigeria. In order to adjust for unequal sampling fractions and correct for possible misspecification and selection bias in the effects model, we estimate a treatment effect model using the doubly robust inverse probability weighted regression adjustments. The results show that variable that enhances intra-household joint decision-making on farm input use and wealth indicators encourage UDP adoption while physiological risks tend to discourage adoption. Differential use of food consumption coping strategies exists between adopters and non-adopters along less severe but not severe strategies. We find that UDP technology can significantly increase food security, measured as food consumption coping strategy index, among adopting households. This implies that the technology is welfare increasing, and its adoption could be discouraged by health and production – related risks interventions.
