Effect of Foliar Application Boron and Calcium on Yield and Fruit Quality of 'Desert Red" Peach Trees.

Abstract

The present experiment has been conducted during the season 2016 on 5-years old 'Desert Red' peach trees budded on 'Nemagurd' rootstock, grown in sandy new reclaimed at El-Nubaria, Behera Governorate, treatments included 0.05% H3BO3 + 0.1% chelated Ca, 0.05% H3BO3 + 0.2% chelated Ca, 0.1 % H3BO3+ 0.1% chelated Ca and 0.1 % H3BO3 + 0.2% chelated Ca, were sprayed after fruit set starting and after five weeks to fruit setting. The results mentioned that all treatments increased significantly shoot length leaf area compared to the control (unsprayed trees). Also, the highest fruit yield was resulted from the application of 0.1% H3BO3 + 0.2% chelated Ca, while the lowest fruit yield was gained from control trees.Furthermore, in general, all treatments increased weight, dimensions, firmness, TSS, Vitamin C and total sugar in fruits of 'Desert Red' peach. However, the most effective treatment for increasing growth and yield as well as improving fruit quality was found from 0.1% H3BO3 + 0.2% chelated Ca in 2016 season of study as compared with control treatment which recorded lowest growth, fruit yield and quality values.
