A huge amount was invested on irrigation project but this project did not achieve the target. Most of these projects have very low water productivity ranging between 0.52-0.60 kg m-3 and 30-50% irrigation efficiency. Lining of the canal and transpiring the management to WUA also could not result. In this scenario, application of pressurized irrigation system in place of surface irrigation system may be a solution. Looking to these facts, this study was conducted in the command of RBC of Samrat Ashok Sagar project. The detailed survey of all the 55 villages of the command area was conducted in order to have an account of present condition. It was found that only flood irrigation system is being practiced in the whole command area. The cropping intensity of the area was determined using previous data. Existing cropping intensity varies between 115% to 196%. Similarly, the existing water productivity was determined. It varies from 0.52-0.60 kg m-3. An increase of 76% in the water productivity was observed, if border irrigation system is replaced by sprinkler irrigation system. Similarly, 116% increase in water productivity was found if flood irrigation system is replaced by sprinkler irrigation system and about 23% increase in water productivity was found if flood irrigation system is replaced by border irrigation system. In order to evaluate this in the farmer’s field 15 farmers (five from each reach) were selected randomly. The ratio of 60:40 of sprinkler irrigation system and border irrigation system was found suitable for RBC command of Samrat Ashok Sagar project in view to enhance the water productivity, water use efficiency and cropping intensity in study area. The water saved through this level was found 9071431 m3 (25%) and thus the additional area 2016 ha (21.21%). may be brought under irrigation through adoption of 60-40% irrigation level technology and increasing the cropping intensity by 8.59%. Prepared conjunctive plan for surface and pressurized irrigation was implemented and evaluated in the 15th farmers field and was found suitable as per recommendations made. A complete plan for entire RBC command area that is for 9503 ha was made and also recommended for implementation.
