Uticaj tipa kombajna i vremena ubiranja na kvalitet ubrane kamilice

This paper is the result of studying effects of mechanical chamomile harvesting on yield and quality of harvested chamomile. Chamomile (Chamomilla recutita (L) Rausch.) was harvested at three time intervals (T1 - 240 days, T2 - 250 days and T3 - 260 days after sowing) by three conceptually different harvesters. The results achieved indicate that the harvester type significantly influences quality of harvested chamomile, whereas it is not influenced by chamomile harvesting time. Quality of harvested chamomile was classified into four categories, and it was observed that the greater number of rotations of a picking device increased the content of the first category of quality. The harvester A achieved 54.79% of the first category of quality in respect to the harvester B achieving 50.26% and the harvester C with 42.93%.Ovaj rad predstavlja rezultat istraživanja u okviru koga su praćeni efekti mehanizovanog ubiranja na prinos i kvalitet ubrane kamilice. Kamilica je ubirana u tri različita vremenska intervala (T1 - 240 dana, T2 - 250 dana i T3 - 260 dana nakon setve) sa tri koncepcijski različita kombajna. Ostvareni rezultati ukazuju da tip kombajna ima značajan uticaj na kvalitet ubrane kamilice, dok takav uticaj nije izražen kada se posmatra termin ubiranja kamilice. Kvalitet ubrane kamilice je klasifikovan u 4 kategorije, gde je uočeno da veći broj obrtaja beračkog uređaja povećava učešće I kategorije kvaliteta. Kombajn A ostvaruje 54,79% I kategorije kvaliteta ubrane kamilice u odnosu na kombajn B sa 50,26% i kombajn C sa 42,93%
