Abstract Background High-yielding variety (HYV) seed breeding has Audio/Video Kits been one key approach to improving agricultural productivity and to reduce global hunger and poverty.This paper explores the causal relationship between high-yielding rice variety, rice productivity, farm income and household nutrition.A challenge with evaluating the impact of changes such as crop varieties on yield is self-selection and endogeneity.

This article robustly identifies marginal input contributions, correcting for self-selection potential by applying matched Difference in Difference method.Results We found that the farms that switched from Apparel local to HYV, experienced around 35% higher yield and 76% higher profit from Aman rice than non-adopting farms.More calorie intake, more protein and especially higher fruit and vegetable intake meant less calorie poverty for adopted households.

Conclusion This recent evidence suggests improved seed remains a high potential return investment for regions of the world where smallholder farming and malnutrition is a wider phenomenon.
