| Abstract | ||||
| Two field experiments were conducted at the Agricultural Research Farm, Faculty of Agric., Minufiya University during seasons of 2004 and 2005 to investigate the effect of some antioxidants i.e., ascorbic acid (vit. C), thiamine (vit. 81), citric acid (CA) and salicylic acid (SA) on vegetative growth, chemical composition, head physical characters and yield and its quality of cabbage grown in summer season. Results indicate that, all the used antioxidants treatments significantly increased plant height, stem diameter, fresh weight of stem, leaves / plant and whole plant, dry matter, total carbohydrates as well as the concentration of N, P and K of cabbage leaves. Moreover, in the presence of this antioxidants, head length, head diameter, number and weight of un-wrapped leaves/plant, edible head weight and total yield were significantly increased. On the other hand, NOJ-N accumulation decreased. In general, spraying plants with ascorbic acid, thiamine at the rate of 1000 mg II and salicylic acid at the rate 300 mg / I gave the best values of vegetative growth and head characteristics. | ||||
