Influence of row spacing on yield and quality of common chamomile [Chamomilla recutita (L.) Rausch.] flower heads
The experiment consisted of three single row spacings (every 25, 40 and 50 cm) as well as four cultivations in belt-type double and triple rows arrangement (40-25-40 cm, 40-25-25-40 cm, 50-25-50 cm, 50-25-25-50 cm). The highest flower head yield was achieved from triple spacing, the lowest – from single spacing every 25 cm. Essential oil content was higher in flower heads from belt and flavonoids from single spacing every 50 cm arrangement. The lowest levels of both essential oils and flavonoids were recorded in raw material from single every 20 cm spacing.
