| Abstract:
The present investigation was carried out in order to study the effect of canopy management and cycocel application on yield and quality attributes, viz: weight of bunch, length of berry, diameter of berry and weight of berry. The investigation was laid out on a four-year-old orchard of Thompson Seedless grape with two replications in Factorial Randomized Block Design. The 7-5 sub-cane pruning was done after April pruning. The treatment consist of: three cane densities, i.e., 30, 35, 40 per vine; three leaf densities, i.e., 14, 16 and 18 per cane after October pruning with application of cycocel at five concentrations viz: control, 250, 500, 750 and 1000 ppm at five leaf stage after October pruning. Significantly highest yield (15.96 kg/vine; 35.44 MT/ha), TSS acid ratio (45.7) with attractive grayish yellow colour of berries and significantly minimum acidity (0.49%) was recorded in cane density 35 per vine, leaf density 16 per cane with application of cycocel 500 ppm at 5 leaf stage after October pruning; however, the highest weight of bunch (439.99), length of berry (k.69 mm), diameter of berry (19.78 mm), weight of berry (3.51 g) was recorded in cane density 30 per vine, leaf density 16 per cane with application of cycocel 500 ppm at five leaf stage after October pruning. | |
