Effect sowing date and Nitrogen fertilization on growth plant Anethum graveolens L
Abstract
A field experiment was conducted, University of AL-Qadisiya on 2010 2011– winter season, to study the effect of two planting dates (20/9 and 20/10 2000) and four levels of nitrogen fertilizer as urea (46% N) (0 , 40 , 80 , 120 Kg N / ha) and their interactions upon growth and volatile oil quantity and quality of Anthum gravcolens L Treatments were arranged according to the randomized complete Block Design as a factorial experiment with four replications. The results can be summarized as fallow: 1.The first planting date had significantly higher plants, greater number of branches. The increased levels of nitrogen fertilizer from 0 up to 120 Kg N / ha increased plant height and diameter of both stem, and branches . However, the plant height, number of branches, diameter of stem were not affected significantly by interaction.- 2. The first planting date increased the number of flower panicles per plant, number of fruits per panicles. Nitrogen fertilization at (40 Kg N / ha) increased the values of these characteristics significantly .
- 3. The results show that the first planting date gave higher oil percentage compared with second planting date, where as the second planting date. Nitrogen fertilization with 40 Kg N / ha gave significantly better increment in oil percentage. Results also showed that the interaction had significant effect upon oil percentage.
