Abstract
To evaluate the effect of different levels of nitrogen fertilizer and municipal compost on the essential yeild of savory pot experiment in 2009 was carried out in the Darab region. Different doses of compost was in four levels, including: zero C0:, 10C1:, 20C2: and 30C3: tons per hectare and nitrogen fertilizer include: zero N0:, 30N1:, 60 N2: and 90N3: kg of pure nitrogen from urea per hectare. Analysis of variance showed that the consumption of different amounts of nitrogen, compost and interaction between them on dry matter yield and height, percentage and yield of essential oil of savory, is statistically significant. Comparison of mean showed that treatment 90 kg N/ha along with 30 tons of municipal compost consumption per hectare (N3C3) with an average 50/8 g dry weight in pot greatest and treatments without N and compost (N0C0) and non-N with 10 and 20 tons of compost ha (N0C1 and N0C2) were mean 23/69, 23/42 and 24/63 g dry weight, the lowest plant dry weight were allocated to pot. N fertilizer and compost on the number of lateral branches per plant and nitrogen application on mean stem diameter was significant. N3 with an average 24/75 lateral branches and C3 with a mean 22/19 lateral branches, were the highest number of lateral branches per plant. N2C3 with mean of 2/13 percent of most essential oil produced. The most essential yield of the combination treatment N3C3, respectively. Generally produce more essential oil percent and to have more dry matter level N2C3 be seems appropriate.
