Effects of vermicompost and foliar application of amino acids and urea on quantitative and qualitative yield of chamomile (Matricaria chamomilla L.)
Abstract:
To study the effects of vermicompost and foliar application of amino acids and urea on quantity and quality of chamomile (Matricaria chamomilla L.), an experiment was conducted at RAN Field Research Station in Firouzkuh, Iran in 2012. The factors were vermicompost (0, 3, 6, 9 and 12t/ha) and foliar spraying (non-spraying or control, amino acid and urea spraying). The experimental design was factorial based on a randomized complete blocks design with 15 treatments and three replications. Results showed that the highest plant height (35.27cm), flower number per plant (181.75), and dry flower yield (2053.7kg/ha) were obtained by urea foliar application. While, the highest essential oil (0.59%), and chamazulene (7.13%), essential oil yield (11.98kg/ha) and chamazulen yield (854.17g/ha) were obtained by amino acid spraying on the plants. The application of vermicompost at a rate of 12 t ha-1 could increase all measured traits significantly. The results of interaction effects showed that the application of vermicompost at a rate of 12 t ha-1 and foliar application of amino acid had positive and significant effects on dry flower yield and chamazulen yield.
