Influence of harvester type and harvesting time on quality of harvested chamomile [PDF]

open access: yesJournal of Agricultural Sciences, Belgrade, 2016
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
