Evaluation of Tillage Methods under Rainfed Cultivation of Cotton-Pulses Crop Rotation

Aims: To evaluate the effect of tillage methods on soil moisture storage, grain yield, economics and rain water use efficiency in semi-arid region
 Study Design: Four viz. conventional tillage, Rotovator ploughing + chisel ploughing, tiller conservation (Minimum with retention crop residue) at different time ploughing.
 Place Duration Study: Kovilpatti, a representative location regions Southern Tamil Nadu. This study was conducted from 2015 to 2021 alternate years rotation cotton greengram.
 Methodology: The field experiments were greengram black under fed situations. Soil samples collected depths assess storage. Yield recorded cost cultivation worked out. Rainwater used for obtaining higher yield calculated. .
 Results: storage subsurface layers followed by rotatvator method. For both crops, plough efficiency, net return.
 Conclusion: clearly indicated that once could be adopted as promising strategy retain availability boost productivity semiarid
