- Abstract
Muscat Hamburg (Panneer) is the most popular cultivar in Tamil Nadu for its pleasant musk flavor. It is consumed as table variety and also used for juice and wine-making purposes. The present investigation was conducted during summer and winter pruning from April 2016 to March 2018, in the grapes vineyard located at Shanmuganathy dam road, Rayappanpatty village in Cumbum valley of Theni district, Tamil Nadu. The experiment was laid out by adopting Randomized Block Design with seven treatments and three replications. The exeprimental results revealed that the treatment with foliar application of chelated EDTA calcium @ 0.2% + boric acid @ 0.1% recorded the maximum number of bunches (41.00 vine-1), fruit yield (14.87 kg vine-1), individual bunch weight (636.87g), bunch volume (498.42 mL) and TSS (19.53ºbrix). The minimum berry cracking (3.46%), titrable acidity (0.52%) and physiological loss in weight (10.18%) were also recorded in the treatment with chelated EDTA calcium @ 0.2% + boric acid @ 0.1% (T5) as compared to other treatments. Further, the same treatment combination noted the lowest berry shattering (2.42%). Whereas the highest berry diameter was recorded in the treatment with a spray of calcium chloride @ 0.3% than all other treatments.
