Field experiment was conducted at Al Sharkia Governorate, Egypt in a private farm through a project of vegetable research Dept. of the National Research Center. The study aims to investigate the effect of foliar application of two commercial fertilizers, i.e. amino magnical an activator for vegetative growth and root most an activator for the root system beside mineral soil fertilization on the growth, yield as well as physical and chemical constituents of onion plants. The important detected results are as follows: 1.Foliar fertilization method reflected increases in vegetative growth of onion plant expressed as leaves number, bulb and neck diameter, fresh and dry weight of leaves as well as N, P and K content and uptake compared with soil fertilization method. Total yield and bulb quality followed the same trend, but the differences in total yield were not significant.2. Foliar application of amino magnical and root most enhanced vegetative growth; N, P and K content and uptake of plant leaves as well as plant weight and total yield compared with soil fertilization. No significant differences were detected in these parameters between amino magnical and root most.3. Higher values of vegetative growth; N,P and K content and uptake by onion plant leaves as well as plant weight and total yield were obtained by two sprays of amino magnical or root most without significant differences in comparison with soil fertilization
