| Abstract | 66The basic aim of the mini sprinkler irrigation method, as in other irrigation methods, is to apply irrigation water as uniformly as possible to the root zone of the crop. The study was aimed to evaluate the uniformity of different mini sprinklers in the Department of Soil and Water Engineering at College of Technology and Engineering, Udaipur. Three commercially available mini sprinklers of different companies (C-1, C-2, and C-3) with nozzle size 2.5 * 1.8 mm, 2.4 * 1.8 mm, and 2.3 * 1.8 mm, respectively, were tested for their uniformity performance in terms of uniformity coefficient and distribution uniformity. The experiment was conducted at four different operating pressures ranging from 2 to 3.5 $kg/cm^{2}$ with increment of 0.5 $kg/cm^{2}$ and at two different riser heights of 50 and 100 cm. All the mini sprinklers were operated for spacing of 10 m * 10 m. The uniformity coefficient and distribution uniformity of mini sprinklers were studied for single-head mini sprinkler pattern method. The best-fit relation between operating pressure and riser height was established and polynomial relationship was found to be best among other relations on the basis of value of their regression coefficient (r$ ^{2}$). From the study, it was also observed that the values of uniformity coefficient and distribution uniformity were more for 100 cm riser height as compare to 50 cm. The uniformity coefficient and distribution uniformity of mini sprinklers were studied for single-head mini sprinkler pattern method. The irrigation uniformity is an important indicator for the evaluation of performance of sprinkler irrigation system. By determining highest uniformity of water distribution for optimum riser height, operating pressure, and proper sprinkler spacing, only required optimum number of sprinklers per unit area can be used, and per hectare cost of the irrigation systems can be reduced. The polynomial relationship was the best fit among all other functions for the mini sprinklers of three different companies at 100 cm riser height. The basic aim of the mini sprinkler irrigation method, as in other irrigation methods, is to apply irrigation water as uniformly as possible to the root zone of the crop. The study was aimed to evaluate the uniformity of different mini sprinklers in the Department of Soil and Water Engineering at College of Technology and Engineering, Udaipur. |
