Abstract

The precise selection of appropriate crops that are compatible with the soil and crop water requirements (CWR) in a particular area is necessary for effective land and water management. A study was conducted to ascertain the agricultural water requirements of a few chosen crops for the Sangareddy District of Telangana. The crops include Rice, Sugarcane, Soybean, Maize, Cotton, Black gram, Green gram, and Bengal gram. Using meteorological data from the past 10 years stored in CROPWAT, the amount of water needed by each crop was calculated. The FAO Penman-Monteith method was used to determine reference crop evapotranspiration (ET0). The study shows that reference crop evapotranspiration, ETo varied from 7.96 mm/day to 3.14 mm/day in the years between 2010 – 2021. The crop water requirement (CWR) and Net irrigation requirement for Rice were 595.5 mm and 331.9 mm, Maize was 366.6 mm and 64.3 mm, Cotton was 612.7 mm and 283.8 mm, Sugarcane was 1902.1 mm and 1189.3 mm, Soybean was 270.9 mm and 0.0mm, the Black gram was 332.1 mm and 22.1 mm, Green gram was 342.7 mm and 13.3 mm and Bengal gram was 344.9 mm and 316.1 mm. The results were accurate R2 was 0.84 compared with the Class A pan. This study demonstrates that the CROPWAT model is helpful for computing the crop water requirement which needs for the appropriate administration of water assets.
