An investigation was conducted to know the “Impact of canopy management on growth and yield of wine grapes under northern dry zone of Karnataka” at division of fruit science at sector 70, UHS, Bagalkot during 2015-16. For the study varieties and cane regulation were considered as main and sub treatments respectively. Among varieties, Shiraz recorded to be early variety with early panicle initiation (17.33 days) and duration of maturity (114.25 days). Medika reported to be superior over other varieties with respect bunch breadth (9.59 cm), weight (326.50 g) and berry characters (12.56 x 12.26 mm LxB and 2.02 g weight) which attributed for higher yield (13.97 kg/vine and 29.84 t/ha). Cane regulation treatment significantly influenced on the yield and yield attributing parameters. Twenty five canes per vine was found to be superior over other treatments with respect to early panicle initiation (18.22 days), early maturation (116.00 days), number of panicles per cane (3.43), number of bunches per cane (2.08), bunch characters (24.22 x 9.33 mm LxB and 299.78 g weight) and berry characters (12.77 x 12.92 mm and 2.41 g). Control treatment recorded significantly the maximum number of panicles per vine (86.44) and bunches per vine (66.56) which attributed to greater yield (15.15 kg/vine and 33.65 t/ha). From the study, cane regulation is essential form of thinning in vineyard operation and considered as a technique which could lead to tremendous improvement wine grapes and helpful for quality wine production.
