EFFECT OF NANOTECHNOLOGY OF POTASSIUM FERTILIZER BY INJECTING MAGNETIZED WATER THROUGH DRIP IRRIGATION ON SUGAR BEET CROP

The field experiment was conducted in Wadi El Natrunq (latitude 30.23⁰N, longitude 30.21⁰E, and elevation 17.98 m above sea level), Beheira Governorate, Egypt, during the 2019-2020 and 2020-2021 growing seasons to study the productivity and quality of sugar beet crop under nano potassium magnetic water and drip irrigation system. The multi-embryo sugar beet variety "Fayrouz" was planted during the first week of October and harvested after 175 days. The field experiment treatments were studied for the effect of magnetic water (MW), and non-magnetic water (nMW). The second treatment used five percentages of potassium with nano potassium, which is (100% potassium, 75% potassium + 25% Nano potassium, 50% potassium + 50% Nano potassium, 25% potassium + 75% nano potassium and 100% nano potassium) respectively. The highest averages of sucrose remaining sugar in molasses, extracted sugar, and quality index were recorded (20.24, 2.27, 17.42, and 88.29) % respectively, with magnetic water by adding (75% potassium + 25% nano potassium). The highest productivity of root and the amount of sugar produced by the crop were (13.88 and 2.41) tons.fed-1, with magnetic water and adding (75% potassium + 25% nano potassium). It was the highest efficiency (8.73, and 6.52) kg.m-3 for the first and second seasons, respectively, with magnetic water and the addition of (75% potassium + 25% nano potassium).
