The field study was conducted on Lysimeter by employing the soil water balance method to compute the water requirement and Crop coefficient of Maize in the temperate climatic zone of India. Non-weighing type lysimeters (drainage type) of 2 × 1.5 × 2 m was installed to compute the irrigation requirement, actual crop evapotranspiration (ETc) and actual crop coefficient of maize by water balance method. The water requirement of maize was found 410.4 mm using lysimeter data. The mean daily reference evapotranspiration (ETo) of maize ranged from 0.91 mm/day in the starting growth period to 5.29 mm/day at midseason. The peak ETo of Maize was found 6.3mm/day. The computed crop coefficient (Kc) values of Maize for diffrent crop growth stages were 0.53 for intial, 0.93 for development , 1.05 for mid-season, and 0.78 for late season .A Correlation was also established between Penman-Monteith (P-M) and four other reference Evapotranspiration methods.

Crop Water Stress

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, Rai Bareilly district of Uttar Pradesh, CROPWAT 8.0 model is used, 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 Lucknow division of Uttar Pradesh.
