Abstract
The sprinkler irrigation water is intended to distribute on the surface, to allow the infiltration without runoff; in addition, the water must be distributed as uniformly as possible way in order to obtain adequate uniformity application in the field. The research objective was to characterize the uniformity of water distribution of sprinkler model D 148 (sector) used for irrigation of vegetables in the region of Rio Verde, GO. Assays were performed in the experimental area IFGoiano - Campus Rio Verde. The relationships pressures, interference pin protector applied on the blade and Christiansen uniformity coefficient (CUC). For testing at a pressure of 4.0 bar without interference from the spreader pin water jet, the Christiansen uniformity coefficient (CUC) was 81.3%.
