Abstract
U sklopu poslovno – tehničke suradnje Zavoda za mehanizaciju Poljoprivrednog fakulteta u Osijeku i poljoprivredne tvrtke Belje d.d., testirano je 5 prskalica na "PJ Brestovac – Karanac" ( 3 Hardi i 2 John Deere prskalice). Iz obavljenih testiranja može se utvrditi da su na testirane prskalice postavljene mlaznice koje odgovaraju ISO standardu te ostvaruju protoke prema EN 13790 standardu. Prema EN 13790 standardu kapacitet crpke može odstupati 10 % od nazivnog kapaciteta. Kod svih ispitivanih vučenih ratarskih prskalica crpke imaju odstupanja u dozvoljenih 10 %. Mjerenje kapaciteta crpki obavljeno je s elektronskim mjeračem tvrtke Krohne. Svi manometri kod ispitivanih prskalica rade u području optimalnog, tj. dopuštenog odstupanja od strane europskog standarda. Najvažniji predmet tesiranja prskalica je stavka koja se odnosi na površinsku raspodjele tekućine. Testiranje raspodjele tekućine je obavljeno pomoću uređaja Spray scanner koji donosi konačnu ocjenu kvalitete rada na temelju rezultata koeficijenta varijcije. Da bi prskalica ostvarila zadovoljavajuću raspodjelu tekućine koeficijent raspodjele tekućine mora iznositi manje od 20%. Nakon obavljenog testiranja zaključujemo da sve prskalice zadovoljavaju kriterije ispravnosti tehničkih sustava u zaštiti bilja te mogu poslužiti kao primjer provođenja dobre poljoprivredne prakse na površinama BELJA d.d.

Parallel abstract (English)
Within business - technical cooperation of the Institute of Agricultural Engineering, Faculty of Agriculture in Osijek, and agricultural company Belje d.d. , it have been tested 5 sprinklers on "PJ Brestovac- Karanac" (3 Hardi and 2 John Deere). From the testing it can be determinated that nozzles have been placed on the tested sprinklers corresponding ISO standard and which generate flows according to EN 13790 standard. According to EN 13790 standard pump capacity may deviate 10% from the nominal capacity. In all tested towed agricultural sprinklers pumps have deviations 10%. Measuring capacity of pumps have been done with electronic meter from the company of Krohne. All manometers from the tested sprinklers works in an optimal area, which is set by the European standard. The most important item from the tested sprinklers has been related with the surface distribution of liquid. The testing was carried out using a Spray scanner which shows the final evaluation of the work quality based on the results of the variation coefficient. To make a good distribution of liquid, liquid coefficient must be less than 20%. Following completion of testing, we can coclude that all the sprinklers can meet the criteria of the correctness all tehnical systems in plant protection, and also can subserve like an implementation sample of the good agricultural practice on the surface of BELJE d.d.
