| Abstract | ||||
| The present work was conducted at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Egypt, during the two successive summer seasons of 2016 and 2017 to investigate the impact of irrigation water (normal water - magnetized water), foliar spraying with K forms (potassium nitrate - potacrysal as a source of nano potassium fertilizer) and levels of soil mineral fertilizers (100 -75 -50 %), NPK from recommended dose and their interactions on vegetative growth and chemical contents of cowpea plants. Obtained data cleared that irrigation with magnetized water produced the highest significant values of plant growth, chlorophylls and chemical composition contents compared to normal water treatments. Meanwhile, fertilized cowpea plants with 100% NPK from recommended dose gave the maximum values of all studied parameters. Moreover, foliar spraying with potacrysal as a nono source of potassium increased significantly all studied characters, except number of branches in the second season. It could be recommended that irrigation cowpea plants with magnetized water, 75% NPK from the recommended dose and foliar spraying with potacrysal in order to limiting the environmental pollution and decrease costs comparing to 100% NPK. | ||||
