Abstract

In order to study of the effect of different rates of fertilizer, manure, micronutrients and mixture of them on flower, seed yields and main composition of essential oil of chamomile, field experiment was conducted in 2006-2007 in a farm located at 5 kilometer from west of Shirvan city. The experimental design was randomized complete block with three replications and eight treatments including: unfertilized (F1), 100% fertilizer (F2), 100% manure (F3), micronutrients foliar (F4), 50% fertilizer +50% manure (F5), 100% fertilizer + micronutrients foliar (F6), 100% manure+ micronutrients foliar (F7), and 50% fertilizer + 50% manure + micronutrients foliar (F8). The results showed that the highest seed, fresh and dry flower yield obtained from 100% fertilizer + micronutrients treatment and there wasnt significant different between this treatment with 100% fertilizer treatment. The highest essential oil and chamazulen percentage obtained from 50% fertilizer + 50% manure and 100% manure treatments. The highest essential oil and chamazulen yield achieved from 50% fertilizer + 50% manure + micronutrients treatment and there wasnt significant different between this treatment and 50% fertilizer + 50% manure treatments.
