Abstract:
Effect of canopy architecture management on growth and yield of grape cultivar Sharad seedless was studied during the year 2020-2021 and 2021-2022 at the Horticulture Garden, Department of Horticulture, University of Agricultural Sciences, Raichur. At 45 days after pruning growth parameters length of the fruiting shoot (cm), diameter of the fruiting shoot (mm), internodal length of fruiting shoot (cm), number of leaves per vine, leaf area per vine (m²) and LAI was not affected significantly by canopy architecture management practices during the present study in grape cultivar Sharad seedless. At 90 days after pruning significantly maximum length of fruiting shoot (108.67 cm), fruiting shoot diameter (6.56 mm), internodal length (5.54 cm) and minimum number of leaves (2977), leaf area (20.31 m²) and leaf area index (4.51) was noticed in ST (T₂) canopy management practice. While significantly minimum fruiting shoot length (81.30 cm), fruiting shoot diameter (5.34 mm), internodal length (4.62 cm) and higher number of leaves (4494), leaf area (39.01 m²) and leaf area index (8.67) was observed in control (T₁). Number of bunches per cane and number of bunches per vine was not effected significantly but numerically more number of bunches per cane (1.16) and number of bunches per vine (40.67) was recorded in LR₁ (T₄). Significantly maximum bunch length (17.83 cm), bunch breadth (11.56 cm), bunch weight (359.1 g) and bunch volume (336.5 cm³) in canopy management practices ST+LR₁ (T₇) and fruit yield per vine (14.00 kg) and fruit yield tonne per hectare (31.11 t ha^-1) was observed in LR₁ (T₄) canopy architecture management practice.
