Abstract

Field experiments were conducted during 2011 and 2012 at Agricultural Engineering College and Research Institute, Kumulur, Tamil Nadu to evaluate the tillage practices, crop residue and supplemental drip irrigation in hybrid maize under dry land condition. Tillage practices and crop residue with supplemental drip irrigation practices lead to significant improvement in growth parameters and yield attributes. The highest grain yield of 6845 and 6789 kg ha-1 in both the seasons, respectively was obtained by minimum tillage with crop residue @ 10 t ha- 1 + supplemental drip irrigation ten times. Therefore, minimum tillage (one pass of moldboard plough followed by two passes of disk harrow) with crop residue @ 10 t ha-1 + supplemental drip irrigation ten times could be recommended for improving yield and profit in hybrid maize under dry land condition
