Integrated nutrient management to enhance on-farm productivity of rainfed maize in India

On-farm trials were conducted in the central Karnataka of India, over 3 years, with the objectives of quantifying the effects of applying balanced nutrition to rain fed maize with regard to yield response, plant nutrition, profitability and rain water use efficiency under multi-nutrient deficient conditions. Maize grain yield was significantly increased by the soil application of Farmers’ Inputs (FI) plus additional quantities of nitrogen and phosphorus (NP), FI+sulfur, boron and zinc (SBZn) and FI+NP+SBZn treatments compared to maize receiving no fertilizer inputs or FI. Optimizing limiting soil nutrients significantly (p
