摘要：The study was undertaken to evaluate the efficient use of sprinkler irrigation system by farmers. Fifty farmers were randomly selected among the farmers who were given sprinkler irrigation system on subsidy basis and collected the data using structured questionnaire in Mannar district from August 2013 to January 2014. Data were statistically analyzed using Microsoft Excel and Minitab 15 software. Results revealed that nearly 73% of the farmers were using the system effectively while the rest 27% did not use at all. Net income from cultivated crops such as groundnut, onion, greengram, greenchilli and cabbage using sprinkler irrigation system were higher than that of the conventional method by 59%, 45%, 47%, 32% and18% respectively. Yield of these crops cultivated under sprinkler irrigation system was significantly different (p0.05) from the yield of those respective crops cultivated with conventional method of irrigation. Uniformity coefficients such as percentage for Christiansens uniformity coefficient and distribution uniformity coefficient for sprinkler irrigation systems in the study area were estimated as 94% and 93% respectively. Over all uniformity of sprinkler irrigation system was in the recommended level. Hence there is potential for the adoption of sprinkler irrigation technology which could increase the yield and the farmers income by increasing the extent of cultivation with the available water resource.
