ABSTRACT
Field experiments were conducted during August-December 2002 (Kharif) and January-April (Summer season) 2003 to study the effect of incorporation of biocompost on lowland rice with four treatments viz., M1-Control, M2-FYM at the rate of 12.5 t ha - 1, M3-GLM at the rate of 6.25 t ha- 1 and M4-Biocompost at the rate of 3 t ha- 1. Rice varieties Co 43 and IR 50 were used as test crops. Among the different organic manures used, application of biocompost at the rate of 3 t ha- 1 registered higher yields and favourably improved the soil chemical and biological properties than the other treatments. Thus, the conversion of by-products like pressmud and distillery spentwash into a value added eco-friendly organic manure can be considered as a commercially viable, environmentally acceptable and practically enforceable option for improving the crop productivity and soil fertility status of the soil.
