Abstract

A study is carried out to determine the crop water requirement of some selected crops for the command area in Markandeya command area. These crops include jowar, Groundnut, Hybrid Maize, Pulses, Mexican Wheat, Bengal Gram, Green Gram and Sunflower. Crop water requirement for each of the crops is determined by using 30-year climatic data. Reference crop evapo-transpiration (ETo) is determined using the FAO Penman Monteith method. For all the crops, crop growth stages such as nursery, land preparation, initial stage, development stage, mid-season and late season stage are considered. The net irrigation requirement is 218.1mm/year. The gross water requirement is 311.57 mm/year with an application efficiency of 70%. Therefore the entire land area of 21290 ha requires 66.33 Million cubic meters. Thus the results of the study dam can conveniently supply the water required for irrigation in the command area.
