Abstract
A field experiment was conducted for two consecutive kharif seasons of 2001 and 2002 to study the effect of integrated use of inorganic fertilizers coupled with organic manures, green manure and phosphate solubilizing bacteria on yield, nutrient uptake of rice and their residual effect on soil fertility in an Ultisol of Mizoram. The results revealed that application of optimum doses of NPK in combination with green manure @ 5 Mg ha−1 recorded highest grain and straw yields and uptake of N, P and K followed by 100% NPK + poultry manure and 100% NPK + FYM. However, the yield and uptake responses were high with the balanced application of NPK in comparison to sub optimal and super optimal doses of NPK. The combined use of organics (green manure/FYM/poultry manure/pig manure) along with the inorganic fertilizers increased the nutrient use efficiency, apparent nutrient recovery and the available nutrient status of the soil. Integrated use of organic manures along with optimum doses of chemical fertilizers not only produced highest and sustainable crop yields but also enhanced the efficiency of added fertilizers as well as fertility status of the soil.
