Integrated Application of Vermicompost and Nitroxin and Quantitative and Qualitative Characteristics of GermanChamomile (Matricaria chamomilla L.)

In order to study the effects of integrated application of organic and bio-fertilizers on quantitative and qualitative characteristics of chamomile (Matricaria chamomilla L.), an experiment was conducted as randomized complete blocks design with six treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of Iran in 2013. The treatments were 4 t/ha vermicompost, 8 t/ha vermicompost, nitroxin biofertilizer, integrated application of 4 t/ha vermicompost and nitroxin, integrated application of 8 t/ha vermicompost and nitroxin and control (without fertilizer). The results showed that treatments had significant effects on studied traits, as the highest dry weight of plant (109 g/p), dried yield of flower (720 kg/ha), essential oil content (0.4%), essential oil yield (2.9 kg/ha) and chamazulene percent in essential oil (24.7%) in treatment of integrated application of 8 t/ha vermicompost and nitroxin were obtained. Also, the highest bisabolol A percent in essential oil (44.4%) in treatment of application of 4 t/ha vermicompost and the highest bisabolol B percent in essential oil (12.4%) in treatment of application of nitroxin were obtained. Generally, the highest yield and quantity and quality of essential oil in treatment of integrated application of 8 t/ha vermicompost and nitroxin were obtained.
