This study aimed to evaluate the effect of different managments of swine wastewater and clean water on clogging of emitters and application uniformity of drip irrigation systems. The experiment was conducted in the experimental area of the Federal University of Viçosa (UFV) and mounted in a split split-plots, having in the plots the managments (1E3A - one hour of application of effluent and three hours of application of clean water, 2E2A - two hours of application of effluent and two hours of application of clean water, 3E1A - three hours of application of effluent and one hour of application of clean water and 4E - four hours of application of effluent), in the subplots the types of drippers (G1, G2 and G3) and in the subsubplots the evaluation times (0, 20, 40, 60, 80, 100, 120, 140 and 160 h) in a completely randomized design with three replications. The results indicated that in the swine wastewater the characteristics suspended solids, total iron and bacterial population represented severe risk of clogging of drippers; and that there was a high reduction of the uniformity of application of effluent when the time of application of wastewater is equal to or greater than the water supply.
