Abstract

In three series of pot experiments (2006–2008) there was investigated a reaction of two cultivars of chamomile (Chamomilla recutita L. Rauschert): diploid ‘Mastar’ and tetraploid ‘Dukat’, with use of biostimulants: Asahi SL and Bio-Algeen S-90 as well as microelement fertiliser Ekolist P. The experiments were performed under stress triggered by high air temperature and low soil moisture. According to the pot experiment results, the application of Asahi SL was the only one which increased the chamomile herb yield. The effect of Asahi SL was tested in a field experiment (2008/2009) which also recorded an increase in the herb yield, yet only in ‘Dukat’ plants. The ‘Dukat’ plants produced higher yield of herb, of a higher content of essential oil in herb than the ‘Mastar’ plants, nevertheless the ‘Mastar’ plants bloomed more abundantly and contained more essential oil in inflorescences. No benefits were observed from application of the microelement fertilizer Ekolist P or the biostimulant Bio-Algeen S-90 to chamomile grown as exposed to moisture deficit and high temperatures.
