| Abstract | ||||
| A field experiment was conducted on Faculty of Agric. El-Mansoura Univ. during season of 2014-2015 to investigate the effect of phosphorus fertilizer levels with foliar application of (gibberellin, humic acid and cyitokinen) on faba bean (var.sakha 4). Sixteen treatments were arranged in a split-block design, which were the simple possible combination between four levels of phosphorus fertilizer i.e. 0,50, 75 and 100% P2O5/fed (recommended dose) for faba bean plant as main plots and four treatments of growth regulators (without, gibberellin (GA3), humic acid (HA) and cyitokinen (CK)), each treatment was replicated three times. The results showed that; soil application of phosphorus fertilizer levels significantly increased the average values of plant growth parameter ,yield and its components and chemical constituents of faba bean plant as well as available N,P and K of soil after harvesting stage . The highest values recorded with using 75% from recommended dose P-fertilizers. With in the growth regulators investigated; a superiority effect was happened on all parameters under study for the plants treated with humic acid following with GA3 and lastly CK as compared to control treatment. Generaly, the most suitable treatment, which realizing the highest yield of faba bean seeds was connected with the treatment of 75 % ( R.D) + humic acid . | ||||
