Abstract

The judicious combination of inorganic fertilizers, organic manures, biofertilizer and green manure is essential for sustained soil fertility. The effect of inorganic fertilizers and in combination with organic manures was evaluated for soil organic carbon (SOC),bulk density, porosity mean weight, diameter, water holding capacity, available soil N,P,K and grain and straw yields of rice and rice-cowpea cropping system in medium black soil from year 2007 to 2012. All the organic manure treatments recorded significantly higher yield of rice than control. Among organic manures application of glyricidia @5 t/ha and poultry manure 5t/ha were at par and recorded significantly higher yield of rice than application of FYM and paddy straw (5t/ha each) which were also at par combination of glyricidia (5t/ha) and N150 recorded significantly higher yield of rice than rest of the combination except poultry manure with N150 and FYM with N150 which were at par.
