Abstract: An experiment was conducted at Horticultural Research Station, Mondouri, BCKV during 2015-2017 to find out the effect of mulching and supplementary irrigation on fruit set, fruit drop, fruit retention and yield of Bael (Aegle marmelos Correa.). The experiment was put on factorial RBD consist of nine treatments viz. M0I0 - No mulch + no irrigation (control), M0I1 - No mulch + basin irrigation @ 15 litres plant-1 at 10 days interval, M0I2 - No mulch + basin irrigation @ 15 litres plant-1 at 20 days interval, M1I0 - Black polythene mulching + no irrigation M1I1 - Black polythene mulching + basin irrigation @15 litres plant- 1 at 10 days interval, M1I2 - Black polythene mulching + basin irrigation @15 litres plant-1 at 20 days interval. M2I0 - Dry leaves mulching + no irrigation, M2I1 - Dry leaves mulching + basin irrigation @15 litres plant-1 at 10 days interval, M2I2 - Dry leaves mulching + basin irrigation @15 litres plant-1 at 20 days interval. Which are interaction of two factor i.e. mulching and irrigation and each treatment has three replications. Result of the investigation revealed that mulching with black polythene followed by no irrigation (M1I0) before flowering improves fruit set (68.67%) than any other treatments. Black polythene mulching + basin irrigation 15 litres plant-1 at 10 days interval (M1I1) was most effective in improving fruit retention (16.33%) and fruit yield plant-1 (34.49 kg) followed by dry leaves mulching + basin irrigation 15 litres plant-1 at 10 days interval (M2I1).
