Evaluation of nutrient expert based fertilizer recommendation for growth, yield and nutrient uptake of maize hybrids and soil properties in maizewheat cropping system in mollisol

Maize is a heavy nutrient feeder crop but over and inappropriate fertilization provides lesser yield than the genetic yield potential, lower profits and deterioration in soil health therefore, a new fertilizer recommendation approach, Nutrient Expert (NE) for hybrid maize was evaluated against farmers fertilizer practice (FFP) in three years maize-wheat rotation. Results revealed that nutrient expert-decision support system based nutrient management gave higher yield, nutrient uptake and profits and sustained soil properties over other practices.
