Effect of in situ soil moisture conservation practices on maize and its crop residue incorporation on yield and economics of succeeding transplanted rice Var. ADT 46

Crop residue incorporation is a key component of sustainable cropping systems. It reduces the adverse effects burning and enhances soil fertility. Effective usage crop in field proper management are required. With this background, experiment was conducted during 2020 – 21 maize-rice sequence at Annamalai University Experimental Farm, Department Agronomy, Faculty Agriculture, University, Nagar, Tamil Nadu to find out residual effect different mulching practices adopted preceding maize stubble on growth, yield economics transplanted rice Var. ADT 46. The Factorial Randomized Block Design with three replications. In factor I, moisture conservation viz., sugarcane trash, water hyacinth, hydrogel control were allotted. II, levels 0, 33, 66 100% provided. Water hyacinth mulched plot (M3) registered significantly (þ <0.05) higher parameters, economic returns succeeding rice. lower values observed unmulched (M1) plot. respect crop, 66% (SI3) returns. interaction effects, + (M3SI3) recorded than other treatments. lowest an incorporated (M1SI4) Mulching rate 12 t ha-1 incorporating into had remarkable advantage financial rewards.
