In order to examine the effect of manure and chemical fertilizers on the some agronomic characteristics, yield and the amount of essence of rosemary, the experiment was carried out as randomized complete design with 9 treatments at 4 replications at in Sari city at 2013. Treatments were included witness (control), sheep and vermicompost fertilizers and chemical fertilizers of nitrogen and phosphorus at 6 different amounts which are N150-P150, N150-P200, N150-P250, N200-P150, N200-P200 and N200-P250. The results showed that the all agronomic traits were very significantly affected by the manure and chemical fertilizers compared to the control.
The effect of the manure fertilizer was statistically more that chemical fertilizers on the all characteristics. The maximum plant height, leaf wet and dry weight, wet yield, dry yield and the amount of the essence of the plant were attained when manure fertilizers applied and the maximum stem wet and dry weight and the total number of the chain stems were also attained by chemical fertilizers. It showed that to increase the quality properties and the amount of the essence of the rosemary plant, the use of manure fertilizers is more effective than chemical fertilizers, statistically. Sheep fertilizers as the manure fertilizers increased all the traits and also the rate of essence significantly compared to vermin-compost fertilizers. Thus, sheep fertilizer can be recommended as the best treatment at the present study.
