Nutrient Expert Improves Maize Yields while Balancing Fertilizer Use

摘要

Nutrient Expert~® (NE) is a simple and rapid tool for generating field-specific fertilizer recommendations. Results from 17 on-farm sites in five districts of Bihar showed that NE significantly increased maize yields and economic returns compared to the generalized State Recommendation (SR) and Farmers' Fertilization Practice (FFP). NE's impact on fertilizer use in maize shifted N and K application upwards while also lowering P application rates.
