On- farm precision nutrient prescription under pre- dominant cereal- cereal systems using Nutrient Expert®

The project was initiated to optimize nutrient usage and maximize cereal – cereal systems productivity in various rice growing ecologies and geographies in India. The research project will compare yield and economic performance of field specific fertilizer recommendation through Nutrient Expert with the existing blanket recommendation for predominant cereal- cereal cropping systems in multiple locations of India.

The project was aimed at optimizing nutrient use and maximizing the productivity of cereal–cereal systems through on-farm precision nutrient prescriptions using Nutrient Expert® (NE), in various cereal-growing areas of India. The study was initiated by the All India Coordinated Research Project on Integrated Farming System (AICRP-IFS) in 11 states of India.

Inadequate and unbalanced fertilizer application in the cereal-cereal cropping systems of India has reduced farm profits and led to multi-nutrient deficiency in soils, while adversely affecting nutrient use efficiency. Survey results revealed that farmers’ fertilizer management practices are characterized by unbalanced N application, optimal to sub optimal P use, while K and secondary or micronutrient use was almost completely neglected.

The project was initiated to optimize nutrient usage and maximize cereal–cereal systems productivity in various cereal growing ecology and geographies in India. The nutrient application in cereal-cereal systems of India is generally imbalanced, leading to low system productivity that not only reduces farm profits but also leads to multi-nutrient deficiency in soils.

Nutrient Expert®: Making Better Fertilizer Use Decisions The preferred method for making fertilizer recommendations is to analyze soils to determine if an adequate nutrient supply exists to support healthy crop growth. However, most farmers in India lack knowledge about managing nutrients within their highly nutrient demanding cereal systems. The IPNI South Asia Program developed and adapted Nutrient Expert® (NE), a decision support software system that provides fertilizer recommendations, for individual maize farmers. Across all of the maize-growing sites, the performance of NE was consistently superior to the other alternatives.
