STUDY THE EFFECT OF USING MAGNETIZED TREATED WATER UNDER CENTER PIVOT IRRIGATION SYSTEM ON POTATO

Study the effect of using magnetized treated water under center pivot irrigation system on Potato. The study was conducted at the International Company for Agricultural Development (Farm Frites, Egypt for potato planting development and for processing it half French fries) in Al-Hashemi Farms - Wadi Al-Natroon - Al-Buhaira Governorate during two consecutive seasons, namely winter season 2018/2019 and summer season 2019. The specifications of the magnetic field and advice as a radiation source for magnetic field were installed; the device is produced through technical standards set by European laboratories with appropriate analysis and quality. Strength, the magnetic field strength of this device is 14000 gauss (1.4 Tesla); source of irrigation water was used from groundwater irrigation. It was used on potato crop Santana cultivar in seasons 2018/2019 and 2019. Considering the previous discussion and the use of magnetized treated water under center pivot irrigation system on potatoes Santana cultivar planted by seeds small sized, diameters 28-35mm and normal sizes with seed diameters 35-45, 45-50 and 50 -55 mm planted in low and high soil salinity with sandy soil at four levels from evapotranspiration (ETc) (110%; 100%, 90% and 80% from ETc with trials two season winter and summer seasons 2018/2019 and 2019. By using magnetized irrigation water (MIW) resulted to:
