In order to evaluate the effect of organic fertilizers (compost) and nitrogen on growth and yield of Moldavian balm, a split plot experiment in a randomized complete block design with four replications in 1393 at the research station of Kerman agricultural and natural resources research and education center was performed. The main plots and subplots of the experiment, respectively, were included compost in 4 levels (0, 10, 20, 30 tons per hectare) and fertilizers contained nitrogen (urea) at 4 levels (0, 42, 60, 78 kg per hectare). The obtained result showed that when the composting were risen from 0 to 30 tons per hectare, the fresh weight of plant (52.5%), dry matter content (39.6%), leaf dry weight (96.2%) and plant height (58.4%) increased and the lowest value was observed in control. Furthermore, the increase in nitrogen (urea source) from 0 to 150 kg per hectare had an increasing effect on these traits. The mean comparison showed that the use of compost and nitrogen, respectively, in amounts of 30 tons and 150 kg per hectare caused the highest yield.
