The effects of phosphorous and nitrogen rates on yield, yield components and essential oil percentage of Matricaria recutita L

In order to investigate the effect of nitrogen fertilizer (0, 40 and 80 Kg from urea) and phosphorous fertilizer (0, 30 and 60 Kg from super phosphat treepal) on yield and essetial oil production of Matricaria recutita L. an experiment has been conducted on the basis of randomized complete block design in three replications at 2007. The results showed that there is significant difference in number and dry weight of flowers between nitrogen fertilizer treatments at the level of 1%. Treatment of 40 kg nitrogen by producing 742.2 flower and 20.63 gr dry weight had the highest yield. Control samples produced 507.06 number of flowers and 10.06 gr dry weight, which is at itś lowest amount. Among phosphorous fertilizers, there is significant difference and the highest yield refers to 60 kg phosphate in hectare. It produced 816.26 number of flowers and 30.17 gr dry weight. Thus, the best recommended treatment is 2nd level of nitrogen fertilizer and 3rd level of phosphate fertilizer, with 40 kg nitrogen and 60 kg phosphate in every hectare. There was no significant difference in chamazolene percentage in all treatments.
