The study was conducted to develop a rotational water allocation plan on the basis of water requirement of crops with reference to a command of Right Main Canal (RMC) of Jaisam and dam situated on Gomtiriver. Diagnostic analysis of water distribution system was conducted to study the operational problems in entire network of RMC and it revealed that there was lack of knowledge among the farmers about optimum water requirements. Canals required maintenance to avoid from a large wastage of water as seepage through cracks on entire RMC. Seasonal crop water requirement for Rabi crops (wheat, gram and barley) were determined using the values of ETo and Kc with consideration of conveyance and application losses. The seasonal crop water requirement for wheat, barley and gram were as 45.60, 32.16 and 35.29 cm respectively. The Field Water Use Efficiency for wheat, barley and gram was 59.20, 46.64 and 17.00 kg/ha-cm respectively. The Crop Water Use Efficiency for the same crops was found as 103.57, 80.09 and 27.93 kg/ha-cm respectively. The conveyance efficiency of RMC was found as 80.62 %, whereas for Phadi, Jhadol and Dingri minor it was found as 75.95 %, 70.68 % and 65.62 %, respectively. It was found that maximum time required i.e., 3.24 days for group no.7, whereas the minimum time required i.e., 0.66 day for group no. 2. Thus all farmers even on tail end were getting their fair shares in proportional to land holding.
