In order to examine the effect of nitrogenous fertilizer value and its splitting during the growth period on morphological traits and essence rate of Maticaria chamomilla L. in spring cultivation in Tabriz, Iran, a factorial, random wholeblock experiment was conducted in triplicates during cultivating year 2009-2010 in Research and Promotive Farm of Basmenj Agriculture Research Center. The treatments in this experiment include three rates of nitrogenous fertilizer 50, 100 and 150 kg/ha along with control one and fertilizing time in four three-phase splitting (b1) 100 percent at cultivation phase, zero at the beginning of flowering, and zero at the middle of flowering, (b2) 50 percent at cultivation phase, 50 percent at the beginning of flowering, and zero at the middle flowering, (b3) 25 percent at cultivation phase, 50 percent at the beginning of flowering, and 25 percent at the middle of flowering, and (b4) zero at cultivation, 100 percent at the beginning of flowering, and zero at the middle of flowering. In general, the results of experiment indicate that, splitting procedure of nitrogenous fertilizer does not have significant effects on the number of pedicle stem diameter, bush height, number of lateral stems, and tiller number. Regarding the effect of nitrogen consumption level on measured traits in the present research, it was determined that, total traits were affected by different levels of nitrogen (on probability 5%). The review of mutual effect between splitting procedure and different levels of nitrogenous fertilizer on essence rate and essence weight of Matricaria chamomilla L. was meaningful, so that, the highest essence weight was obtained in third treatment and by using 150 kg/ha net nitrogen and also highest rate of essence was related to third treatment with 150kg/ha net nitrogen. Therefore, based on the results of the present research, it appears that the cultivation of Matricaria chamomilla L. along with consumption of 150 kg/ha net nitrogen is suitable in climatic conditions of Tabriz through splitting procedure including 25 percent at cultivation, 50 percent at the beginning of flowering and 25 percent at the middle of flowering. It is expected that the maximum yield of Matricaria chamomilla L. is obtained under conditions of Tabriz along with consumption of nitrogenous fertilize lower than 150 kg/ha
