Abstract

tn an experiment conducted during 1997 98 and 1998 99, incorporation of crop residues of either rice (Oryza sativa L.) straw or wheat (Triticum aestivum L. emend. Firori Paol.) straw increased the yield and yield compo nents of rice and nutrient uptake and also improved the physico chemical properties of the soil which provided bet ter soil environment for crop growth. Increasing levels of NPK application increased the yield attributing characters and nutrient uptake by both the crops which ultimately increased the grain and straw yiekls thus, 100% NPK levels gave the highest yield. There was no significant effect on physico chemical properties of soil due to increasing lev els of NPK application.
