Effect of Zinc and Boron on growth and quality of grapes cv. Muscat

摘要

Soil and Foliar application of micronutrients viz. Zn and B applied either individually or in combination enhanced the growth and quality of six year old matured muscat grapes under irrigated conditions. Foliar application of ZnSO_4 0.5 per cent + borax 0.2 per cent combination applied twice during vegetative and full bloom stages excelled others in increasing the shoot length number of internodes shoot~(-1), number of leaves shoot~(-1) and quality characters with highest juice per cent, total soluble solids (TSS), total sugars, sugar / acid ratio and lowest acidity.
