RESIDUAL EFFECT OF MUSHROOM SPENT RICE STRAW COMPOST ON YIELD AND NUTRIENT UPTAKE IN GREEN GRAM

Abstract

The greenleaf manure and mushroom green gram spent rice straw compost applied to the previous crop namely the rice, registered the highest green gram grain yield than composted coirpith and NPK alone. With reference to the soil nutrients, greenleaf manure registered the highest organic C, available N and K, available P by farm yard manure and Ca and Mg by mushroom spent rice straw compost. All the manures were comparable in influencing the N, Ca and Mg uptake whereas P and K uptakes were not influenced by the manures.
