Abstracts: In the sprinkler irrigation method, water is sprayed into the air and allowed to fall on the ground surface somewhat resembling rainfall. The spray is developed by the flow of water under pressure through small orifices or nozzles. Generally the wheat crop is irrigated by border irrigation method in Saurashtra region. Losses of water in border irrigation method is found to be enormous, therefore there is necessity for evaluation of the use of sprinkler irrigation. The present experiment was conducted to study the feasibility of sprinkler irrigation method for wheat crop. The experiment was carried out at our farm of village Fagari, Ta. Keshod, Dist. Junagadh in the Rabi season (Dec. to March) of 2013-14. The experiment was laid out on 104 m x 24.4 m plot size and sprinkler system keeping distance 12.2 m x 12.2 m between two lateral and two sprinkler on lateral. Irrigation was applied at 50 per cent soil moisture deficit. Total 11 numbers of irrigation were applied. Crop yield, moisture use efficiency and grain quality were analysed. Three empirical equations for estimation of irrigation scheduling used and actual water used were compared with result of these equations. Economic analysis for present experiment was also done. Trend of water saving by sprinkler irrigation system compared to border system was also supported by studies carried out at Haryana Agricultural University, Punjab Agricultural University and at Himachal Pradesh. Our study clearly shows that comparison of yield of main produced, by-produced, water use efficiency and depth of water applied in sprinkler and border irrigation systems, which indicates higher yield, low water utilization, & higher water use efficiency by sprinkler irrigation.
