ESTIMATION OF CROP WATER REQUIREMENT FOR BORO RICE IN BANDARBAN, BANGLADESH BASED ON CROPWAT 8.0 MODEL
Asian Journal of Plant and Soil Sciences, Volume 6, Issue 1,
Crop water requirements (CWR) is crucial to the choice of irrigation plants and plant structures in specific areas, notably in Bandarban, Bangladesh, that that give economical water use and higher irrigation practices, corresponding to performed to estimate irrigation needs and irrigation of boro rice (watered within the dry season) was programmed in the Bandarban region of Bangladesh using the FAO CROPWAT model. The seven crop growth stages (nursery, nursery/land preparation, land prepearation, initial, development, mid-season, late season) and three decades (I, II, III) were considered for boro rice. This study calculable the harvest reference evapotranspiration (ET0) and irrigation requirements of boro rice grown in the area. The several climate data from 1988 to 2018 were collected by the Chattogram meteorological Station, the model calculable 40.77mm /day ETo within the study area, of that the best quantity of 4.30 mm/day in April and therefore the lowest 2.36 mm/day in December. The evapotranspiration of the cultures ranged from 0.29 mm/day to 4.84 mm/day. The results showed that the typical annual precipitation and the effective precipitation were 300.7 mm/day. mm or 105.1 mm for plant growth and development. The irrigation water demand resolves to be 543.5 mm/dec. This was compared to the irrigation water demand knowledge calculated by CROPWAT to assess whether or not or not farmers were active in associate economic irrigation application.
