In Eastern Uttar Pradesh, which is part of this fertile Indo-Gangetic Plains, the International Rice Research Institute has been promoting the Rice-Wheat Crop Manager (RWCM). RWCM is a web-based decision-support tool for precise nutrient management that can be accessed through a smartphone or computer connected to the internet.
Using the principles of site-specific nutrient management (right source, rate, time, and place), RWCM offers field-specific nutrient management advisories to farmers based on their responses to the app’s built-in questionnaire. On-farm evaluation trials using RWCM have increased rice and wheat yield by 0.5-1 tons/ha/season with a net added benefit of USD 100- 150/ha/season.
