A field experiment was carried out at Agricultural College and Research Institute, Madurai, during the winter (rabo seasons of 2000 and 2001, to study the effect of cotton (Gossypium sp.) crop residue management prac- tices and levels of inorganic fertilizer N and K on rice (Oryza sativa L.) and succeeding blackgram (Phaseolus mungo L.) in rice-blackgram cropping system. Incorporation of cotton stalks Q 5 tonnesfha with Trichoderma viride in rice crop significantly improved the growth parameters, yield attributes and yield of rice. Maximum re- sidual effect was observed with the incorporation of cotton stalks Q 5 tonnesfha + T'richoderma viride, that re- sulted in the marked improvement in the growth, yield attributes and yield of succeeding blackgram. Similar yield trend was seen by increasing levels of N and K fertilizers in rice and blackgram.References
