Abstract: 

German chamomile (Matricaria Chamomilla) is one of the most important essential oil bearing plants that its essential oil constituent is used in different medicinal industries. A field experiment was conducted using a split plot design with three replications in Eqlid, Fars, Iran in 2013. The treatments were included three amounts of vermicompost (0, 5 and 10 ton.ha-1) and five drought stress an irrigation after (60, 90, 120, 150 and 180 mm evaporation pan class A). Analysis of variance showed that the main effect of vermicompost and drought stress on the number of branches, number of main stem and flower yield was significant. Comparison of means showed that the maximum flower yield (441.50) was obtained from lowest of drought stress (60 mm evaporation pan class A). Also, analysis of variance showed interaction of treatments on height, biological yield, essential oil and essential oil yield were significant. Comparison of means the interaction between drought stress and vermicompost levels for essential oil percent showed that for the irrigation levels after 60, 150 and 180 mm evaporation from evaporation pan, the highest and lowest essential oil percent was obtained from 10 tons and no application of vermicompost per hectare, respectively. Based on the results of this experiment can be expressed, however, by reducing water consumption, Consequently, the occurrence of drought stress, German chamomile flower yield decreases, but with the use of manure vermicompost (in the highest level of stress), can partially reduce the negative effects of drought stress on plant yield.
