INFLUENCE OF CLIMATIC FACTORS ON UNIFORMITY IN SPRINKLER IRRIGATION

Abstract

Field experiment was conducted to assess the influence of climatic factors over the uniformity of water distribution with sprinkler irrigation system. The influence of the climatic factors, viz, wind velocity, relative hymidity and atmospheric temperature over the uniformity coefficient was studied. Sixteen combinations of four nozzle diameters and four pressures were tried for each irrigation with ragi as test crop. It was found that wind velocity alone had high negative correlation with uniformity coefficient and the contribution of other factors was not significant.

Keywords: Sprinkler irrigation, climatic factors, influence
