Abstract: The underground water level is declining at an alarming rate and it is necessary to improve the performance of submersible pumps. During summer, the water level at different locations in this zone drops below the optimum range of the pump causing a low discharge as well as poor performance of the existing tubewells of the RPCAU, Pusa Farm area. The additional descent of pumping level further deteriorates the working condition. In the present study, the efficiency of all the four existing submersible pumps of the study area was calculated and thereafter total crop water requirements of the farm was estimated. During the study it was found that maximum pumping head in the study area is 27.77m and output power ranges from 5.11 hp to 12.09 hp, the pump discharge varies from 14.50 litres/sec. to 33.23 litres/sec. and maximum and minimum efficiency of the exiting submersible pumps was found 60.45% and 51.04% for pumps installed at Harpur 1-B and Harpur Jhilli-B respectively. Existing four submersible pumps in the study area has been used to irrigate total farm area of 76.80 ha, under different crops. Total crop water requirements for the study area were found 45.3 ha-m. Available amount of water from the existed tubewells for the whole cropping season was also calculated which was 105.5 ha-m. Thus, it is evident that, there is no need to install any extra tubewell in the study area and the crop water requirements will be met from the existing tubewells.
