Two field experiments were conducted during 2014 and 2015 summer seasons in the experimental farm of the Faculty of
Agriculture at Moshtohor, Benha University to study the effects of spraying cabbage plants (Brassica oleracea var. capitata) cv.
Balady with mineral nutrients i.e., potassium (K2O) at 2g/l, chelated calcium (Ca) at 2g/l, micronic sulphur (S) at 5g/l, boric acid
at 100mg/l and antioxidants salicylic acid (SA) at 50mg/l, citric acid at 2g/l and amino acids at 2ml/l all of these materials are
dissolved before spraying either in normal water (30±1) or in cold water (4±1). Growth and head production including some
quality characteristics were investigated. The obtained results revealed that cold water showed positive and significant effect in
case of non- consumable outer leaves and those inner and consumable ones as well as the fresh weight of formed heads. As for
the interaction effects of nutrients and the antioxidants dominantly were significantly and positively affects different estimated
growth and productivity aspects. Also, results confirmed the beneficial effects of applying such low costs treatments to minimize
different disorders those facing cabbage production in high temperature summer plantings. These beneficial effects of such
applied treatments were prolonged to the quality characteristic of formed heads with high and rich edible value. |
