Abstract: The present study was conducted during 2016/2017 and 2017/2018 on seven years Valencia orange trees in a private orchard in Nubaria, Behera governorate, Egypt to evaluate the effect of magnetically treated irrigation water (MTW) and well water either alone or with adding humic acid, calcium silicate and microorganisms on the leaf mineral, carbohydrate and proline contents, vegetative growth, yield and fruit quality .The results indicated that using magnetized water and all other treatments gave a significant increase in the studied growth parameters as well as tree yield and fruit quality.The magnetized water plus magnetite treatment increased leaf phosphorus and iron.Trees treated with magnetized water plus humic acid had the highest new shoot numbers, TSS, TSS/acidity content and juice weight, as well as the lowest peel thickness.Magnetized water plus calcium silicate gave the highest leaf area, tree yield, fruit diameter, fruit firmness and leaf silicon content.Magnetized water plus Microorganism consists of mixture of yeast -photosynthetic and lactic bacteria and sterptomycetes (EM) treatment caused the most height of tree, Canopy circumference, trunk circumference, and leaf nitrogen and zinc.Mgnetized water plus calcium silicate and magnetized water plus EM treatments showed the highest leaf carbohydrate and fruit vitamin C content.Magnetized water plus humic acid and magnetized water plus EM treatments gave the highest leaf potassium.Fruit weight was highest by magnetized water plus humic acid and magnetized water plus magnetite.It has been concluded that use of magnetized water technique with humic acid, silicon and EM applications would be an economically and safe alternative tool to solve the problem of irrigating with saline water and to enhance orange tree growth and productivity grown under similar conditions of the present study.
