YIELD, CROP WATER PRODUCTIVITY AND ECONOMIC BENEFIT OF BOTTLE GOURD (Lagenaria siceraria) PRODUCTION

On a farm, bottle gourd production usually involves one or two irrigation episodes. The goal of this study was to find the best irrigation period for yield agricultural water production and financial gain, regardless of whether water is plentiful or scarce. During two seasons, the experiment was carried out at the regional agricultural research centre at Hathazari, Chittagong (from November 2019 to February 2020, and from November 2020 to February 2021). Rainfed condition (T1), irrigation at three-day intervals (T2), irrigation at three-week intervals (T3), irrigation at flowering stage (T4), and irrigation at fruiting stage (T5) were used in a randomised complete block design with three blocks and five treatments: rainfed condition (T1), irrigation at three-day intervals (T2), irrigation at three-week intervals (T3), irrigation at flowering stage (T4), and irrigation at fruiting stage (T5) (T5). Based on production (approximately 76 tonne ha-1), crop water productivity (28 kg m-3), and financial advantage (benefit/cost ratio = 3.5), irrigation at three-day intervals was the best method for bottle gourd farming. Irrigation at the flowering stage increased output, crop water productivity, and benefit of bottle gourd more than irrigation at the fruiting stage. In the event of water scarcity, the crops should be irrigated more frequently at field capacity. Otherwise, because of water shortage and the limited scope of a single irrigation event, the blossoming stage should be irrigated.
