An experiment was conducted in grapes cv. Red Globe during 2012-2013 for two seasons namely rainy and summer at Horticultural Orchard, Tamil Nadu Agricultural University, Coimbatore to study the effect of four different pruning levels on leaf nutrient status and chemical properties of vine with five replications and four treatments in a Randomized block design. Results revealed that, either in rainy or summer season all the canes of vines which were pruned for 50% of canes to 2 bud level and remaining 50% of canes to 6 bud level registered the maximum chlorophyll ‘a’ (0.665 mg/g and 1.375 mg/g), chlorophyll ‘b’ (0.494 mg/g and 0.647 mg/g), total chlorophyll content (1.160 mg/g and 2.022 mg/g), total carbohydrate content (14.63% and 15.88%), petiole nitrogen (2.816% and 2.688%), petiole phosphorous (0.827% and 0.864%) and petiole potassium content (2.782% and 2.825%), respectively. Among two seasons, summer season crop performed better than rainy season crop. It was recommended that pruning 50 per cent of the canes for vegetative growth and remaining 50 per cent of canes for crop yield in both seasons were found to be better, considering the performance in both seasons.
