Abstract

Seven experiments were conducted for two consecutive years (2001 and 2002) at farmer's field to study the effect of integrated management of fertilizers, FYM and green manuring on productivity of rice, major nutrient uptake and soil fertility in rainfed uplands. Application of soil test based N, P, K and S (80, 26, 25 and 20 kg ha−1), FYM (5 t ha−1) and green manuring to upland rice produced significantly higher mean grain yield of 3.36 t ha−1. The highest N, P and K uptake was also associated with the conjunctive use of soil test based application of N, P, K and S, FYM and greenmanuring treatment. There was a build-up of available N, P and K in soil in all integrated nutrient management practices including fertilizers alone over the farmers practice.
