| Abstract | ||
| A study was conducted during winter season (2007– 2008) at Muhammad Al-Qasim plant nursery to investigate the effect of nitrogen and phosphorus fertilization levels and interaction between them on the growth and seed yield of Ammi majus L. The treatment included the levels of nitrogen (0, 100 and 200 kg N/ha , as urea (46 % N) and three levels of phosphorus ( 0, 50 , 100 ) kg P/ha as triple super phosphate P O (47 %), using randomized complete block design (RCBD) with three replicats. The results can be summarized as follow: 1- The nitrogen fertilizer leads to significant increase in plant height, number of branches/ plant and dry weight/ plant at 200 kg N/ha. Also the phosphorus fertilizer leads to significant increase in plant height, number of branch/plant and dry weight/plant at 100 kg/ha (10.27 cm,147.03 branch/plant ,117.66 g/plant) in comparison with control. 2- The nitrogen and phosphorus application at the rate 200 kg N/ha with 100 kg P/h was gained highest weight of fruits/plant (68.80 gm), weight of 1000 ruits (0.932 gm) and total fruits yield (2611.8 kg/ha.) | ||
