Water application methods vary in their efficiency of water use and related yield, capital investment, longevity of equipment, labour and associated high technology. Drip irrigation has proved to be an efficient irrigation system for almost all fruit crops. Papaya is one of the important fruit crop grown in Chhattisgarh state, India. The performance of drip irrigation in combination with plastic mulching was evaluated for the papaya crop under Chhattisgarh plain agroclimatic region. A field experiment was conducted applying 10 combinations of treatments, i.e. with and without drip irrigation and with and without plastic mulch. The results revealed that the drip irrigation with plastic mulching on papaya crop had twin benefits of yield increase and water saving. The drip irrigation at 0.6V (V=Ep × Kp × Kc Sp Sr × Wp) volume of water with black plastic mulch of 25 micron thickness showed superior performance towards yield and yield attributing character of papaya as compared to other treatments. The net seasonal income was also found to be higher with the benefit cost ratio of 1:3.85 under the same treatment.
