Abstract
Two experiments were carried out at experiments farm station, National Research Center, at Shalakan, El-Kanater El-Khairya, Kalubia Governorate, Egypt, for two successive seasons of 2004/2005 and 2005/2006 to study the response of Sideritis montana L. plant to different sources of nitrogen, (i.e. Urea, compost and Azotobacter at the levels 50,75 and 100N unit), with three different sowing dates (30th September, 30th October and 30th November). Data indicated that all nitrogen sources increased vegetative growth (plant height, number of branches/plant, herb fresh and dry weight) and chemical composition (essential oil % and yield/plant, flavonoides %, total chlorophyll content, carotenoids content and carbohydrate %) significantly, compared to untreated plants. Moreover, raising the N level resulted in steady significant increases in vegetative growth parameters and chemical composition. In general, the second sowing date (30th October) was the most effective date on promoting the vegetative growth. It can be recommended that for the best vegetative growth and flavonoides content of Sideritis montana L. plants, the seeds should be sown on 30th October, while for the highest essential oil % and yield, plants should be sown on 30th September, and the plants should be supplied with the highest level of compost plus Azotobacter in both sowing dates.
