Sažetak
Voda za navodnjavanje je jedan od ograničenih resursa i sa njim se mora efikasno upravljati, da bi se zadovoljile potrebe useva za vodom. Zato se vodeni resursi moraju koristiti tako da se zaštite i sačuvaju raspoložive količine vode na najefikasniji način, i tako eliminišu nepotrebni gubici i rasipanje vode. U ovom istraživanju se procenjuje ujednačenost i efikasnost distribucije vode sistemom za navodnjavanje sa rasprskivačima pomo u šezdeset uložaka u različitim intervalima rastojanja od 0,5m x 0,5m; 1m x 1m; 1,5m x 1,5m i konačno sa rastojanjem od 2m x 2m. Rezultati ispitivanja rasprskivača pokazuju da se vrednost Christiansen koeficijenta uniformnosti raspodele vode (CU) kre e od do 9 , uniformnost distribucije ( U) u rasponu od 79% do 88%, a koeficijent zakazivanja sistema (Sc) u rasponu od 1,13 do 1,27. Predviđene performanse sistema i isporuka vode za navodnjavanje prema rasprskivačima pomažu u smanjenju: operativnih troškova, gubitaka vode, i znatno se pove ava prinos useva.
