Field experiment was conducted in two consecutive growing seasons at Agricultural Engineering College and Research Institute, Kumulur, Tamil Nadu to evaluate the tillage practices, crop residue and supplemental irrigation through drip irrigation in maize under rainfed condition. The experiment was laid out in strip plot design with three replications. The main plot treatments were conventional tillage, minimum tillage without crop residue, minimum tillage with crop residue @ 5 t ha-1 and minimum tillage with crop residue @ 10 t ha-1. The sub plot treatments were control (without irrigation), supplemental drip irrigation 4, 6, 8 and 10 times during the cropping period. Tillage practices and crop residue with supplemental drip irrigation practices could potentially lead to significant difference in growth parameters, microbes populations, yield attributes and maximum yield 8345, 8856 kg ha-1 of maize in both the seasons by application of minimum tillage with crop residue 10 t ha-1 + supplemental drip irrigation ten times. Therefore, minimum tillage (one pass of mouldboard plough followed by two passes of disk harrow) with crop residue 10 t ha-1 + supplemental irrigation through drip irrigation ten times was found to be more appropriate and profitable to improving yield of maize under rainfed condition.
