Trees were grown at a private orchard under reclaimed conditions (sandy soil and saline water), to study the effect of humate compounds and magnetic iron soil application on tree vegetative growth, yield and fruit quality were studied. There was significant improve by the different humate compounds and magnetic iron treatments on the vegetative growth, yield and fruit quality.
Whereas, 1000 g magnetite plus 50g K-humate was the best results for the most vegetative growth parameters, yield production and the fruit quality and economically treatment under this study during both seasons.
Key words: Valencia orange, Magnetic iron, magnetite, Humate compounds, vegetative growth, yield, fruit quality.
