Abstract

A pot experiment was conducted in the greenhouse of the National Research Centre, Egypt to investigate the effect of potassium foliar fertilizer and irrigation by agricultural drainage water (ADW) on mineral status of Jatropha plants. Plants sprayed twice with Mono potassium phosphate (MKP). Potassium foliar fertilizer (100 and 200 ppm) and irrigated by mixed drainage water (0, 25 and 50% ADW). Irrigation by ADW adversely affected the mentioned growth characters. The highest effect was shown by irrigation of water contains 50% FW+50% ADW. Some macronutrients ratios were included.
