This study investigated the variation in nutrient content in grape petioles and berries throughout the growing season. Seasonal variation and stage-wise changes in grape fruit yield and quality were correlated with a corresponding nutrient concentration in the plants and berries. The results show that, among medium vines, Perlette exhibited lower plant and fruit characteristics than Anab-e-Shahi. Among the growth stages, the highest was noticed in D9 and the lowest in D1.
