| Abstract | ||
| Experiment was conducted during the winter season of 2012-2013 in the farmlocatedin the desert of Al-Zubair region, Basrah Governorate to study the effect of pinching and nitrogen fertilizer levels (as urea) in the chemical content of the leaves of plants and yield of some green pea cultivars irrigated with saline water .The experiment included 18 factorial treatments which were the interaction among pinching treatments (pinching and without pinching) , the three levels of nitrogen fertilizer (0,20,40) kg urea/Donam and the three imported cultivars of green pea (Rando,Nano,Queen).Complete Randomized Block Design was used with three replicates . Results were analyzed by the analysis of variance of split-split plot experiment and mean values were compared using the Revised Least Significant Difference Test at 0.05 probability level.. The results showed that there was no significant effect of pinching in chemical components of the leaves of the plant and yield. Queen and Rando cultivars showed significant superiority in most of the studied characteristics compared with Nano cultivar. fertilized plants at the level of 40 kg urea / Donam significantly dominated in dry weight of the plant , the percentage of nitrogen , phosphorus and potassium and the amount of chlorophyll and total soluble carbohydrates in the leaves and plant yield of green pods and fresh seeds compared with non-fertilized plants. According to statistical analysis, most of the first and secondary order secondary and tertiary interactions had significant differences in their effect on studied characteristics. Non-Pinched plants of Queen cv. fertilized with 20 kg urea/Donam gave the highest yield per plant of green pods 251.0 , and the same cultivars which punch and fertilization at levels 40kg/donam gives a height product of fresh seeds of plant reach 146.4g. | ||
