( 2019). Impact of Magnetic Water on Soil Fertility and Faba bean Productivity under Reducing Phosphorus Fertilizer Rates in Salt Affected SoilsJ. of Soil Sciences and Agricultural Engineering, Mansoura Univ., Vol 10 (12):781 - 786, 2019
Abstract: This study aims to optimize of P fertilizers unit and alleviation soil salinity stress using irrigation with magnetic water. Two field trials on faba bean (Vicia faba L.; Variety Giza 843), were conducted at Tag El-Ezz Agricultural Research Station, Agricultural Research Centre (ARC), Dakahlia Governorate, Egypt during two successive winter seasons of 2015/16 and 2016/17. The experiment treatments were included two factors 1) two irrigation water treatment (tab and magnetized water) and 2) three rates of P fertilizers (50, 75 and 100% from recommended P application). The two factors were layout in split plot design with three replicates, where the water and P fertilizers treatments were located randomly in the main and sub plots, respectively. The obtained results indicated that irrigation faba bean plants with magnetic water treatment surpassed significantly irrigation with tab water under all rates of P fertilizers in all recorded parameters. Regarding irrigation with magnetic water, the increasing reached 21.45, 24.24 and 40.17% in plant height (cm), plant weight (g) and seeds yield (g plant-1) at harvest compared to irrigation with tab water of both seasons. As well as the improvements in concentration of N, P, K, Ca and Mg in seeds reached 19.01, 79.59, 49.43, 22.18, and 10.06 % respectively compared to irrigation with tab water. Finally, irrigation with magnetic water and P fertilizer at a rate of 100% from recommended application was considered as most suitable treatment for obtaining the highest yield of faba bean under these experimental conditions.
