Abstract:

An experiment on effect of bunch load on berry quality, yield, raisin recovery and biochemical parameters in Thompson Seedless grapes grafted on 110-R rootstock was carried out in ICAR National Research Centre for Grapes, Pune during 2015-16. The crop load was adjusted to 50, 75, 100 and 125 bunches per vine. Increase in number of bunches/vine reduced the leaf area index. Highest LAI (1.24) was observed in treatment with 50 bunches/vine. The treatment also observed highest shoot length (68.65 cm), shoot diameter (7.85 mm), inter nodal length (5.74 mm), bunch weight (316.59 g), berry length (21.20 mm) and 50-berry weight (144.2 g). However, with an increase in bunch load per vine reduction in total soluble solids (19.2 o Brix) was observed in treatment with 125 bunches/vine. Similarly an increase in yield/vine of 28.25kg and raisin recovery of 27.10% was recorded in same treatment. Significant differences were recorded for biochemical parameters of raisin obtained from different bunch load. Thus it was observed that though with an increase in bunch load, yield and raisin recovery increases but for production of quality raisins low bunch load should be maintained.
