Abstract

                                A field experiment was conducted for two years during north-east monsoon period to study the effect of in-site water harvesting measure on different crops under rainfed condition at the Agricultural College and Research Institute, Killikulam, Tamil Nadu. Among the moisture conservation practices, contour ploughing was significantly superior to contour bunding but was on par with broad based ridging. Economics wise cowpea and castor were found to fetch more profit.

Key words : Moisture conservation, contour ploughing, contour bunding. broad based ridging
