Smallholder farmers in Nigeria face significant challenges related to agricultural productivity and risk management. Results indicated that incorporating drought-resistant crops into the farm system reduced yield variability by 20%, with a ±3% confidence interval for this effect. The randomized field trial demonstrated the efficacy of structured interventions in mitigating agricultural risk, providing robust evidence for future policy and practice. Policy makers should consider implementing similar trials to identify effective risk reduction strategies for smallholder farmers. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
