Improving of Hayany Date Palm Production by Using K-Humate as Soil Application and Magnetic Water Irrigation at South Sinai Governorate Egypt

T HE present investigation was carried out during 2018 and 2019 seasons to investigate the consequences of K - Humate with and without magnetic water irrigation on yield, fruit quality and some mineral composition of Hayany date palm cultivar cultivated in South Sinai Research Station (Ras Sudr), Desert Research Center, South Sinai Governorate, Egypt. Results showed that there was significantly effect by using K – Humate as a soil application and magnetic water irrigation in both seasons. Treatment K – Humate at 300 g/tree with magnetic water irrigation produced higher yield and bunch weight. The same treatment gave the highest fruit weight, flesh weight, fruit size and fruit dimensions in both seasons. Also, data showed that the total soluble solids, reducing sugars and nonreducing sugars content in fruits increased significantly by application of K – Humate and magnetic water irrigation. However results indicated that such treatment gave the highest values of N, P, K, Ca and Mg contents in pinnae of Hayany date palm cultivar in the first and second seasons compared with the control and other treatments.
