Performance Evaluation of Sprinkler Irrigation System in Ganderbal District J&K State
Journal Title: Current Journal of Applied Science and Technology - Year 2017, Vol 25, Issue 5
Abstract
Field experiments were carried at Krishi Vigyan Kendra (KVK), Shuhama (Jammu and Kashmir) 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 micro sprinkler arrangement was made of two types – point arrangement and linear arrangement. The volume of water was collected in water containers, systematically leveled on the 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 experiment was kept 1.5 Kg/cm2 and 2.0 Kg/cm2. The pressure was measured by a pressure gauge. The riser height was kept 0.75 m and 1 m respectively. The data revealed that uniformity coefficient varied from 82.83 to 88.7 percent in point arrangement of micro sprinklers, whereas uniformity coefficient varied from 86.10 to 91.76 percent in case of the linear arrangement of sprinklers. Experiments revealed that the change in riser height and operating pressure affected the uniformity coefficient significantly. Data also revealed that wind velocity was found to be low in the morning as compared to evening. However, wind velocity didn’t show a significant effect on uniformity coefficient as wind velocity was found to be very low in the experimental area.
