Performance Evaluationof Sprinkler Irrigation System

Field experiments were carried at Krishi Vigyan Kendra (KVK), Shuhama to study the performance evaluation of sprinkler system. The climatic conditions of previous years were obtained and were taken into consideration before the starting of the experiment. The climatic conditions recorded for the experiment were wind speed and wind direction. The microsprinkler arrangement was made of two types ¿ point arrangement and linear arrangement. The volume of water was collected in water containers, systematically levelled on ground surface and placed 0.75 x 0.75 m apart. The volume of water was measured by the aid of measuring cylinder. The water flow pressure for the experiments was kept 1.5 kg/cm2 and 2.0 kg/cm2. The pressure was measured by pressure gauge. The riser height was kept 0.75 m and 1 m respectively. The data reveled that uniformity coefficient varied from 82.83 to 88.7 per cent in point arrangement of micro sprinklers, where as uniformity coefficient varied from 86.10 to 91.76 per cent in case of linear arrangement of sprinklers. Experiments reveled that the change in riser height and operating pressure affected the uniformity coefficient significantly.
