Effect of integrated nutrient management on productivity, nutrient uptake, soil properties and economics of soybean-wheat cropping system in western Maharashtra

Abstract

This study was conducted at IFS, MPKV, Rahuri in Western Maharashtra. The soybean grain equivalent yield in respect of the system in T5 was significantly superior over the rest of the treatments except T6. Amongst different sources of organics, substitution of 50% N through FYM recorded significantly higher system productivity (5458 kg ha-1) in terms of soybean grain equivalent yield. The total nitrogen uptake (210 kg ha-1), total phosphorous uptake (35kg ha-1), total potassium uptake (90 kg ha-1) of soybean was recorded significantly highest in the treatment T5 (100% recommended NPK dose through fertilizers) which was at par with T6. The highest gross monetary returns, net returns with B: C ratio was recorded in the treatment involving use of 100% RDF in both the seasons which was closely followed by treatment T6 (50%N through FYM + 50 % RDF followed by 75 % RDF during Rabi).
