Field experiment on the performance of aerobic direct seeded rice (ADSR) under red and laterite zone of West Bengal was conducted at Rice Research Station, Bankura, West Bengal, India during summer season, 2012. The experimental soil was sandy loam with acidic in nature (pH: 5.2). The results exhibited that the grain yield (1 t ha -1 ) of rice in aerobic situation was low. This might be due to high atmospheric temperature during flowering period, which results in poor grain setting in panicle and most of them became chaffy due to spikelet sterility. Ultimately, it produced low grain yield of rice in aerobic situation during summer season due to high temperature at flowering period, grain formation and grain ripening stages. Thus, aerobic rice system of cultivation needed good management practices.
The experiment was conducted at Horticultural Research Station, Mondouri, BCKV during 2015-2017 to find out the effect of mulching and supplementary irrigation on physical and chemical properties i.e fruit weight, length, diameter, pulp percentage, TSS, acidity, vitamin-C, anthocyanin etc. 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 with 15 litres/plant at 10 days interval, M0I2 - No mulch + basin irrigation with 15 litres/plant at 20 days interval, M1I0 - Black polythene mulching + no irrigation M1I1 - Black polythene mulching + basin irrigation with 15 litres/plant at 10 days interval, M1I2 - Black polythene mulching + basin irrigation with 15 litres/plant at 20 days interval. M2I0 - Dry leaves mulching + no irrigation, M2I1 - Dry leaves mulching + basin irrigation with 15 litres/plant at 10 days interval, M2I2 - Dry leaves mulching + basin irrigation with 15 litres/plant at 20 days interval. Which are interaction of two factor i.e. mulching and irrigation and each treatment has three replications. Mulching with black polythene followed by basin irrigation with 15 litres/plant at 10 days interval was most effective in improving fruit weight (1089.17g), size (length 12.89cm and diameter 39.18cm) and pulp content (56.16%) followed by dry leaves mulching + basin irrigation 15 litres/plant at 10 days interval. The fruit quality like vitamin C and anthocyanin content were also improved by mulching with black polythene followed by basin irrigation 15 litres/plant at 10 days interval but TSS, acidity whereas total sugar content in the fruits were not affected due to mulching and supplementary irrigation
The soil texture of the experimental field was sandy loam having 6.8 pH. The experimental site was situated in the sub-tropical humid climate where summer and winter both are short and mild. Maximum temperature was ranging from 35.62ºC to 23.35ºC and that of the minimum temperature from 23.75ºC to 8.09ºC during the period of the investigation. Major rainfall was received during the month of June and July. The relative atmosphere humidity prevailed during the period of the experiment varied from 91.32 % to 66.04 %. The experiment was laid out in a Randomized Complete Block Design (RCBD). Which comprised of five treatments viz., T 1 -CCC (cycocel) at 0.2 percent,
