Study on Water Requirement of Rice Using CROPWAT Model for Lucknow Division of Uttar Pradesh
Study on Water Requirement of Rice (Oryza sativa) Using CROPWAT Model for Lucknow Division of Uttar Pradesh
Due to the overuse of available water resources, it has become very important to define appropriate strategies for planning and management of irrigated farmland one of the major practices adopted by the researchers for estimating water requirement of the crop is modeling. For determination of crop evapotranspiration and yield responses to water in agro-ecological units (AEUs) of Lakhimpur Kheri, Sitapur, Lucknow, Unnao, Hardoi, Rae barely district of Uttar Pradesh, CROPWAT 8.0 model is used, which was developed by the Land and Water Development Division of 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. This paper is been focused on the study of water requirement for Rice crop in Eastern Uttar Pradesh field with deep loamy soils, deep, silty soils at Uttar Pradesh.
