Grape vine originated in Armenia as one of the temperate fruit crop got acclimatized under tropical condition. A field investigation on standardization of pruning severity and season for yield in grape variety Muscat Hamburg was carried out during the period from 2014 to 2015 in the farmer’s field, M.S.S. Farms, Kamayagoundanpatty, Cumbum Valley, Theni district in Tamil Nadu. The field experiment was undertaken by adopting Randomized Block Design with eleven treatments replicated thrice. The details of the severities on pruning treatments were: Pruning at 3, 5, 7, 9 bud levels, forward pruning and cane pruning during summer and rainy seasons. The results of the pruning experiment revealed that treatments, T2 (Pruning at 3 bud level) and T4 (forward pruning) recorded the highest trunk girth (4.65 and 4.40 cm). During both the season the treatment T2 and T1 (Pruning at 3 bud level) recorded the highest cane girth (0.64 and 0.56 cm) and internodal length (5.53 and 6.17 cm). The highest numbers of canes per vine (44.03 and 46.21), bud sprouting (16.00 and 16.09 days) and leaf area (235.20 and 239.27 cm2) were recorded in the treatment T8 and T7 (Pruning at 9 bud level) in summer and rainy season crops. The severities of pruning had exhibited pronounced effect on yield per vine. The treatments T7 and T8 (Forward pruning) registered the highest yield vine-1 (13.60 and 17.92 kg yield-1) during summer and rainy season crops.
