Nutrient Expert (NE) for Wheat, a new nutrient decision support tool, is based on the principles of site-specific nutrient management (SSNM) and recommends balanced application of nutrients based on crop requirement. The tool was a joint development of wheat stakeholders in India including representatives from national research and extension system, private industries, International Maize and Wheat Improvement Center (CIMMYT), and International Plant Nutrition Institute (IPNI). It enables crop advisers to rapidly develop field-specific fertilizer recommendations for wheat using existing site information. Field evaluation showed that the location-specific nutrient recommendations from the tool increased yield and economic benefits of wheat farmers as compared to the existing practices.
