Abstract :

An experiment was conducted in 1401 in the lands of Andzaq village, Meshgin Shahr city, located in Ardabil province. Application of vermicompost: at two levels of zero (V0) and 5 tons per hectare as soil application before planting (V1), application of growth promoting bacteria (PGRP) as inoculation with seeds, at 2 levels: inoculation with a mixture of 2 Azospirillium and Azotobacter bacteria (F1) and without inoculation (F0), - Nitrogen from urea source: in 3 levels zero (N0) and 50 (N50) and 100 kg/ha (N100) in pure form. The results showed that the combined use of vermicompost and inoculum has a synergistic effect and growth-promoting bacteria with vermicompost can work in a better environment and substrate and can fix nitrogen. So that the effect of vermicompost in improving the percentage of essential oil in different levels of nitrogen varies from 15% in N0 to 3% in N50 and up to 10% in N100. The effect of using different levels of nitrogen on the yield of essential oil was very significant, so that the use of 100 kg of nitrogen was about 79% effective on the yield of essential oil, and the use of 50 kg of nitrogen was also about 42% effective on the yield and the yield reached 836 kg. In high amounts of nitrogen, the percentage of camazolin increased. The lowest amounts of alpha-bisabolol amount to 19.4%, 19.8, 20.7 and 21.
