Effect of organic production of german chamomile (Maricaria chamomilla L.) on itʹs chemical composition

To study the effects of organic production on chemical composition and some agronomic characteristics of German chamomile, an experiment was conducted at College of Agriculture, Ferdowsi University of Mashhad, during years 2002-2003. A split plot arrangement based on randomized complete block design with three replications was used. Treatments consisted of four manure levels (0, 30, 40, 50 tons/ha) and five mixture ratio with pot marigold (100:0, 75:25, 50:50, 25:75, 0:100), wich were allocated to main plots and subplots, respectively. Results showed that use of manure had no significant effect on dry matter and leaf area in german chamomile. Decreasing the ratio of german chamomile in mixture, declined itʹs dry matter, leaf area and seed production. Chamazulene content was affected significantly by leaf area index and seed production. This study showed that use of manure and mixture at 50 percent ratios or lower of german chamomile and pot marigold, is a suitable system of german chamomileʹs organic production wich give a suitable yield with high chamazulene content, without using chemical fertilizers.
