dc.description.abstractThe experiment conducted in the vineyard using sprayers was aimed at analyzing the effect of air flow rate and sprayer movement rate on pesticide droplets deposition on leaf surface. The concentration used was 350 l/ha. Ventilator capacity was changed obtaining the following air flow rates in front of vineyard rows: 5.2; 7.5; 9.8 and 13.5 m/s. Air flow rates were combined with different sprayer movement rates (5.8 and 8.5 km/ha) in order to obtain eight variants. Increasing sprayer movement rate from 5.8 to 8.5 kg/h tended to raise pesticide droplets deposition by 25% in the row facing the sprayer, or 10% on the opposite side of the row. It can be concluded that droplets deposition on the leaf surface was the greatest at the sprayer movement rate of 5.8 kg/ha and air flow rate ranging from 8 to 10 m/s.en
dc.description.abstractEksperiment realizovan u vinogradu primenom orošivača imao je za cilj da odredi uticaj brzine vazduha i brzine kretanja agregata na depoziciju zaštitne tečnosti na lisnoj površini. Eksperiment je realizovan sa normom tretiranja od 350 l/ha. Menjajući kapacitet ventilatora pomoću broja obrtaja rotora, ostvarene su brzine vazduha neposredno ispred reda vinograda: 5,2; 7,5; 9,8; i 13,5 m/s. Kombinacijom navedenih brzina vazduha sa brzinama kretanja orošivača od 5,8 i 8,5 km/h dobijeno je osam varijanti ogleda. Rezultati istraživanja pokazuju da povećanje brzine kretanja orošivača sa 5,8 km/h na 8,5 km/h depozicija na lisnu površinu se povećava i do 25% na strani reda prema orošivaču odnosno oko 10% na suprotnoj strani reda. Na osnovu rezultata istraživanja zaključuje se da je najveća depozicija na lisnu površinu ostvarena pri brzini orošivača od 5,8 km/ha i brzini vazduha ispred reda u opsegu od 8 do 10 m/s.sr
