Abstract

This study was carried out at Al-Kanater Research Station, El-Kaluobia Governorate during the two successive seasons of 2012-2013 and 2013-2014, to investigate the effect of magnetized water on minimizing strawberry mineral fertilization. Four treatments were used i.e., tap water plus 100 % NPK (control), magnetized water plus 50 % NPK, magnetized water plus 75 % NPK and magnetized water plus 100 % NPK of the recommended mineral fertilization rates. Data were recorded on some vegetative growth characters, early and total fruit yield, some physical and chemical fruit quality parameters and macro and micro elements in leaves. Results indicated that irrigation with magnetized water plus 50% NPK of the recommended fertilization rate showed the highest values of total chlorophyll, total carbohydrates, early and total yield, fruit firmness, total soluble solids in fruits and water use efficiency as compared with control. Moreover, magnetized water plus 75% NPK of the recommended rate of mineral fertilization showed the highest values of NPK and manganese contents. In general ascorbic acid was decreased by using magnetized water. The study recommend using 50 % of the recommended NPK fertilization rates plus magnetized water to increase yield and quality of strawberry.
