Abstract:
Given the excessive use of water resources, it's crucial to establish suitable strategies for the planning and management of irrigated farmland. One of the main methods used by researchers to estimate crop water requirements is modelling. Crop water requirements of crops in agro-ecological units (AEUs) of Lakhimpur Kheri, Sitapur, Lucknow, Unnao, Hardoi, Rae barely district of Uttar Pradesh computed with CROPWAT 8.0 using the meteorological parameters. Wheat, rice, sugar cane, apples, mango, pulses, oil seeds, and potatoes are the main crops of Uttar Pradesh. For the determination of crop evapotranspiration and yield responses to water, CROPWAT 8.0 model is used, which was developed by the Land and Water Development Division of the Food Agricultural Organization (FAO). It includes a simple water balance model that allows the simulation of crop water stress conditions and estimation of yield reductions based on well-established methodologies. An experiment to study the water requirement of Rice crops for Eastern Uttar Pradesh fields with deep loamy soils, and deep, silty soils in Uttar Pradesh.
