Alleviation of High Temprature in Cabbage Plants Grown in Summer Season Using Some Nutrients, Antioxidants and Amino Acids As Foliar Application with Cold Water.

Abstract

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 (K 2 O) 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.

Growth and Productivity of Two Cabbage Cultivars Grown in Sandy Soil as Affected by Foliar Spray with Npk Fertilizer and Amino Acids

“…The interaction between OS Cross cultivar and spraying with amino acid at 3 ml/l + NPK (15-15-15) fertilizer at 2 ml /l significantly increased head diameter and head circumferences, followed by the interaction between OS Cross cultivar and spraying with amino acid at 1.5 ml/l + NPK (15-15-15) fertilizer at 1 ml /l in both seasons. Mohamed and Zewail ( 2016) revealed that spraying with amino acids at 2 ml/l increased head diameter and circumference of cabbage cv Balady compared to control (spraying with normal water ).…”

“…two seasons (El-Afifi et al ,2014). Spraying with amino acids at2 ml/l increased head fresh weight of cabbage cv Balady compared to spraying with normal water (Mohamed and Zewail , 2016) .…”

“…Foliar spray with amino acid at 2 ml/l caused highly significant increases in stem diameter, whole stem weight, number of total leaves/ plant, weights of outer leaves (inedible), inner leaves (edible) and total leaves/ plant of Chinese cabbage compared to the control (unsprayed) treatment in both seasons ( El-Afifi et al , 2014). Spraying with amino acids at2 ml/l increased plant height, stem lenth, number of leaves / plant, number of outer and inner leaves / plant, stem fresh weight and plant fresh weight of cabbage cv Balady compared to spraying with normal water (Mohamed and Zewail ,2016).…”

Effect of Spraying Some Microelements and Bio-Stimulants on Yield, Quality and Storage Ability of Red Cabbage Heads

“…Meanwhile, Sarkar et al (2007) found that foliar spraying of micronutrients Zn, Fe and Mn, significantly increased the yield of some vegetable crops. Foliar application of boron increased vegetative growth parameters, chemical constituents, yield and quality of cabbage (Devi et al, 2012;Mohamed and Zewail, 2016).…”
