During 2009/ 2010 and 2010/ 2011 seasons strawberry cv. Festival plants received three sprays at 30, 45 and 60 days after planting with seven antioxidants namely citric acid at 500 ppm, vitamins B complex, K, E, D, A each at 50 ppm and ascorbic acid at 500 ppm either singly or in combinations. The study focused on the effect of these antioxidants on growth, yield as well as physical and chemical characteristics of the fruits. Results revealed that single or combined application of the seven antioxidants (citric and ascorbic acids, vitamins namely B, K, E, D and A) was very effective in improving plant height, number of leaves per plant, diameter and weight of fruit, early and total yields, total soluble solids %, total sugars %, total anthocyanins and reducing total acidity % comparing with the control treatment. The promotion was associated with using citric acid at 500 ppm, ascorbic acid at 500 ppm, K + E + D + A vitamins each at 50 ppm, in ascending order. Combined application of these antioxidants was preferable than using each antioxidant alone. According to the obtained results, application of mixture of all antioxidants (citric acid and ascorbic acids each at 500 ppm, B + K + E + D + A vitamins each at 50 ppm) was suggested to be beneficial for promoting yield quantitively and qualitatively of strawberry cv. Festival.
