A field experiment was conducted in Chhattisgarh, India, during 1999-2000 to study the effects of trickle irrigation and surface method with and without plastic mulching on mango cv. Dashehari. The treatments comprised: basin irrigation with V volume of water (control, T1); basin irrigation with V volume of water + plastic mulch (T2); trickle irrigation with V volume of water (T3); trickle irrigation with V volume of water + plastic mulch (T4); trickle irrigation with 0.8 V volume of water (T5); trickle irrigation with 0.8 V volume of water + plastic mulch (T6); trickle irrigation with 0.6 V volume of water (T7); trickle irrigation with 0.6 V volume of water + plastic mulch (T8); trickle irrigation with 0.4 V volume of water (T9); and trickle irrigation with 0.4 V volume of water + plastic mulch (T10). T8 gave the highest yield (29.80 t/ha), fruit width (5.82 cm) and length (8.89 cm), fruit weight (163.65 kg), net return (Rs. 15 800.00) and benefit:cost ratio. T10 gave the highest water use efficiency (0.052 t ha-1 mm-1).
