Improvement of Hyany Date Palms Production as Affected by Magnetite Soil Application and Magnetic Water at South Sinai

Abstract

At the Experimental Station at Ras Sudr Egypt's South Sinai Governorate, this study was successfully carried out during two seasons (2018 and 2019) on fourteen years – old Hyani dates palm cultivar planted at 8 X 8 meters apart grown with drip irrigation in sandy soil. (EC= 9.19 dS m −1 ). This work included two factors first magnetite (Mag.) levels (0, 250, 500 and 750 g/tree/year) as a soil treatment second two types of water irrigation first magnetic water (MW) second non-magnetic water (non-MW) arranged in a completely randomized design. From the acquired results, it was shown that applying magnetite to the soil and irrigating with magnetic water had a substantial impact on all the analyzed attributes over both seasons. MW enhanced all studied parameters, components of the production, fruit properties, and leaf mineral content compared with non-MW irrigation during each season. Magnetite soil application at 750 g/tree with MW irrigation had the maximum yield, fruit and flesh weight, fruit length and diameter, total soluble solids, total sugars, reducing sugars and non-reducing sugars and leaves mineral contents (N, P, K, Ca and Mg) compared with the control and other treatments in the two seasons and reduce leaf proline content than the control ones.
