Effect of sowing date and harvest frequency on flower yield, essential oil percent and composition of chamomile (Matricaria recutita) CV. Presov
To determine the effect of sowing date and harvest frequency on flower yield, essential oil percent and composition of chamomile (Matricaria recutita) CV. Presov, prepared from Slovakia, an experiment was conducted. The experimental design was split-plot in the basic of randomized complete blocked design (RCBD) with three replications. Main plots consisted of three sowing dates (6 Nov, 5 Mar, and 4 Apr) and sub-plots included three harvest frequencies (first, second and third). Evaluated traits were dry flower yield, essential oil content and yield, yield of β-farnesene, α -bisabolol oxide B, α -bisabolol, chamazulene, α -bisabolol oxide A. The results showed that sowing date, harvest frequency and their interaction had significant effect as measured traits as concerned. On the basis of the results, the most dry flower yield (40g/m2) was obtained from the second harvest of 6 of November. Also the highest essential oil content (0.72 percent w/w), essential oil yield (0.26g/m2) and α-bisabolol yield (0.2375g/m2) were obtained from the second harvest of March and the most chamazulene yield (0.0473g/m2) was obtained from the third harvest of March that it had a little difference with second harvest. According to the results, the best chamomile quality was attained in second harvest of March sowing date in Mashhad condition.
