Abstract
The study was conducted at El-Kwamel farm, college of Agriculture, Sohag University, Egypt during three seasons (2021,2022 and 2023) to evaluating the effects of the interaction of foliar application of NPK in Nano-form at different doses of potassium (k) on Egyptian lime trees with applying different irrigation levels to find out the optimum level of irrigation, to enhance vegetative growth and productivity under environmental stress conditions. Thirty six uniform trees of Egyptian lime were sprayed as foliar application twice in the morning when the leaf stomata are open with Nano - NPK included three rates of potassium (k) i.e. (20:20:20), (20:20:40) and (20:20:60) at 2500 ppm were applied prior to flowering start and after one month from fruit set besides 3 trees as a control with  three levels of irrigation water: 50, 75 and 100% of  Field Capacity (FC). Based on the results, this study recommends the foliar application of Nano-NPK (20:20:40) at 2500 ppm twice—once before flowering and once one month after fruit set—combined with irrigation at 100% of field capacity (FC) as an effective practice for Egyptian lime growers to improve vegetative growth, yield, and fruit quality.
