AB  - Proper protection and quality work of sprayer enable the optimization of the pesticide application and reduces the harmful effects on the environment and human health. The efficiency of the implemented protection is reflected in several aspects, and one of the most important is the quality of the work of sprayers, that is, the equality of pesticides distribution with nozzles. The paper presents an analysis and comparison of test results in the framework of the inspection of field crop sprayers in the exploitation conditions of central Serbia, in accordance with European standards EN 13790, which prescribes methods and equipment for inspection. The aim of the research was to determine the quality of the work of chests and the uniformity of the flow of various sprays, depending on the defined parameters. The test equipment used 'AAMSSALVARANI' measuring equipment, and the flow of the nozzles was measured by the SN S001 individual nozzles. On the basis of the obtained results, it was concluded that the average values of the flow of the sprayer amounted to 0.954 l min-1 (typ A), 1.169 l min-1 (typ B), or until 1.190 l min-1 (sprayer typ C), where the coefficient of variation was in the range 12.24% to 29.49%.
AB  - Pravilnom zaštitom i kvalitetnim radom prskalica omogućuje se optimizacija aplikacije pesticida i smanjuje štetni uticaj na životnu sredinu i zdravlje ljudi. Efikasnost izvedene zaštite ogleda se sa više aspekata a jedan od najznačajnijih je kvalitet rada prskalica, odnosno uniformnost distribucije pesticida rasprskivačima. Rad predstavlja analizu i upoređenje rezultata ispitivanja u sklopu inspekcijske kontrole ratarskih prskalica u eksploatacionim uslovima centralne Srbije, u skladu sa evropskim normama EN 13790 koji propisuje metode i opremu za obavljanje inspekcije. Cilj istraživanja je bio da se utvrdi kvalitet rada prsaklica i uniformnost protoka različitih rasprskivača u zavisnosti od definisanih parametara. Za ispitivanje je korišćena merna oprema 'AAMSSALVARANI', a protok rasprskivača je meren pomoću ispitivača pojedinačnih rasprskivača SN S001. Na osnovu dobijenih rezultata zaključeno je da su prosečne vrednosti protoka rasprskivača iznosile 0,954 l min-1 (tip A), 1,169 l min-1 (tip B), odnosno 1,190 l min-1 (tip C), pri čemu je koeficijent varijacije bio u rasponu 12,24% do 29,49%.

AB  - The paper presents an analysis and comparison of the results of exploitation testing the different machines for soil tillage under conventional and reduced tillage, as well as evaluating the quality of the two types of sowing in the production of buckwheat and winter rye, in the conditions of northern Kosovo and Metohia. The previous crop was mercantile maize. The aim of this study was to determine the effects of the aggregate labor indicators for tillage and seeding, in the production of winter rye and buckwheat, and the results will enable proper selection of appropriate technological and technical systems and pointing out the advantages and disadvantages of the applied systems for tillage and seeding. In a variant of conventional tillage in relation to reduced tillage fuel consumption was higher by 27.41 up to 27.73%, while the yields of buckwheat was lower by 22.02%, and winter rye up to 20.18%. Measured values of longitudinal and lateral distances, and depths of buckwheat and rye seeds, are numerically processed using inverse distance interpolation method. Consequently, an appropriate contour maps that present distributions of relative frequencies with respect to longitudinal and lateral seeding distances, as well as seeding depths, are drawn. These maps clearly illustrate accuracy quality of work and operational stability of two analyzed seeding machines having quire different designs of seeding apparatus, in the working conditions of buckwheat and rye seeding.
AB  - Rad predstavlja analizu i upoređenje rezultata eksploatacionih ispitivanja različitih mašina za obradu zemljišta u okviru konvencionale i redukovane obrade, kao i ocenu kvaliteta rada dva tipa sejalica u proizvodnji heljde i ozime raži u uslovima severnog Kosova i Metohije. Predkultura je bila merkantilni kukuruz. Cilj istraživanja je bio da se utvrde pokazatelji efekata rada agregata za obradu zemljišta i setvu u proizvodnji heljde i ozime raži, a dobijeni rezultati omogućiće pravilan izbor odgovarajućeg tehnološko-tehničkog sistema i ukazati na prednosti i nedostatke primenjenih sistema za obradu zemljišta i setvu. U varijanti konvencionalne obrade u odnosu na redukovanu obradu potrošnja goriva je bila veća za 27,41-27,73%, pri čemu su ostvareni prinosi heljde bili manji za 22,02%, a ozime raži za 20,18%. Kvalitet rada sejalica obuhvatio je određivanje uzdužnog, poprečnog i rasporeda zrna po dubini setvenog sloja. Izmerene vrednosti uzdužnih i poprečnih rastojanja kao i dubine setve heljde i raži, su numerički obrađene metodom interpolacije inverzne udaljenosti. Na osnovu toga, urađene su odgovarajuće konturne mape koje predstavljaju distribucije relativne učestalosti u odnosu na uzdužna i bočna rastojanja semena pri setvi, kao i dubinu setve. Ove mape jasno pokazuju kvalitet rada i radnu stabilnost dveju analiziranih sejalica sa različitom konstrukcijom setvenog aparata, u uslovima rada pri setvi heljde i raži.
