| Abstract | ||||
| This study was carried out through two successive seasons (2021 and 2022) for investigating potassium silicate influence on potato plants (Solanum tuberosum L.) under water stress. It was aimed to enhance potato plants growth process and yield parameters by using different concentrations of potassium silicate (500 & 1000 ppm) as well as the control under different levels of water supply (100, 75 and 50% of ETc i.e. evapotranspiration) in sandy loam soil conditions at Belbeis region – El Sharkia Governorate, Egypt. Data obtained during both experimental seasons revealed obviously that all the treatments enhanced both plants growth process and yield parameters as compared to control. However, spraying with potassium silicate (1000 ppm) with irrigation requirement (ETc 100% or 75%) particularly were statistically the highest treatments in this study, while the most effective treatment for water productivity was potassium silicate 1000 ppm combined with water supply ETc 75%, which produced 12.63 kg for every 1 meter cubic from irrigation water. | ||||
