| Abstract | ||
| A field experiment was conducted in the research field of the College of Agriculture / University of Kufa in 2003-2004 winter season , to study the effect of two planting dates (15/9,15/10/2003) and four levels of nitrogen fertilizer as urea (46%N)(0,100,200,300 kg N/ha) and for levels of phosphate fertilizer as triple super phosphate (48-52% P2 O5) and their interactions upon shoot parameters (plant height ,stem diameters, number of branches, shoot yield, dry weight of shoot and its percentage of dry weight of shoot ) and root parameters( dry weight of root and its percentage of dry weight of root) of Coriandrum sativumL. Local variety .Treatments were arranged according to the randomized complete block design (R.C.B.D) as a factorial experiment with three replications. The results showed the earlier planting date had significantly best in number of branches, dry weight of shoot and its percentage of dry weight of shoot. Increasing levels of nitrogen from 0 up to 300 kg N/ha improvement shoot and root growth parameters Significantly, that the fertilized plant with 300kg N/h gave best plant height (82.31cm), number of branches per plant (9.23),shoot yield (106.19gm), dry weight of shoot (36.09 gm), the percentage of dry weight of shoot (33.93) root dry weight (5.06 gm) and it percentage (36.08) significantly compared with not fertilized plant which gave the least parameters (72.37cm, 7.33, 75.55 gm, 15.61 gm, 20.49%, 1.58 gm and 30.30%) respectively. More that fertilization with 300 kg P2O5/h increasing significantly the number of branches, shoot yield and its dry weight to (9.02, 99.83 gm and 28.17 gm) compared with the plant not fertilized which gave the least parameters. From the interaction between three factors the results showed that the early planting date and fertilized with nitrogen at 300 kg N/ha or phosphors with 300 kg P2O5 /ha gave the best results significantly (number of brancher, shoot yield, dry weight of shoot, dry weight of root). | ||
