Effect of Magnetic Water, Number of Irrigation, Foliar Application with Salicylic Acid and Potassium on Productivity and Quality of Sugar Beet

Abstract

This study was carried out at Tag Al-Ezz Agricultural Research Station, in 2018/2019 and 2019/2020 seasons to find out the impact of two kinds of water (magnetic and field canal water); number of irrigation (5, 4 and 3 irrigations) and foliar transactions (without, spraying with water, salicylic acid at 300 mg/l and potassium sulphate at 4%) on sugar beet yield and quality characteristic. Each kind of irrigation water was achieved in a separate experiment. In each experiment, a strip-plot design was used with three repeats. Maximum growth, quality traits and yields/fed were recorded by irrigating beets with magnetized water. Supplying plants with 5 irrigations produced the highest values of root and foliage fresh weight, root length and diameter, as well as root and top yields/fed. Irrigating beets four times/season attained highest gross sucrose, extracted sucrose and quality index percentages, as well as corrected sugar yield/fed. Spraying plants with K2SO4 at 4% resulted in the highest values of growth, quality characteristics and yields/fed. Under condition of this study, irrigate sugar beets four times with magnetized water and spraying it with K2SO4 at 4% can be recommended to raise its production and quality traits.
