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

Abstract

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.

Minimizing the Adverse Impact of Drought on Corn by Applying Foliar Potassium Humate Combined with Chitosan

“…Furthermore, Mohammed et al (2021) referred to the possibility of replacing some of the potassium soil applications with foliar applications of KH without affecting tomato yield and growth, as well as the nutritional status of tomato plants grown in newly reclaimed sandy soil in Egypt. In the same context, Ataya et al (2022) and Hegab et al (2022) mentioned a similar result of the importance of applied foliar applications of KH on date palms and oat grown in sandy soil in Egypt. Also, in corn plants, humic compounds enhanced root growth, carbohydrates, nitrogen responses, and photosynthesis (Canellas et al 2013;Chen et al 2022); it can lead to more improvements in soil physical properties, biological activities, and acceleration of nutrient transfer to plants (Amjad et al 2014;Pukalchik et al 2019).…”

Magnetic Iron–Improved Growth, Leaf Chemical Content, Yield, and Fruit Quality of Chinese Mandarin Trees Grown under Soil Salinity Stress

“…These results are compatible with the earlier work of Mohamed et al [ 36 ], who stated that the TSS (%) of Balady mandarin fruit juice increased by magnetic iron treatments at concentrations of 500 and 750 g.tree −1 compared to that of untreated trees. Similarly, application of magnetic irrigation water increased the TSS of Hayany date palm trees [ 46 ]. Mohamed [ 41 ] found that magnetic treatments at concentrations of 250 g.tree −1 increased fruit TSS parentage in ‘Keitt’ cv.…”
