Effect of Leaf Removal on Composition of Wine Grape Varieties Grown in Semiarid Tropical Climate of India

Removing leaves from cluster zone is one of the management practices followed to improve fruit composition in temperate wine grape growing countries. However, knowledge on canopy management practices to improve fruit and juice composition for quality wine making is still lacking in semiarid tropical...
