Combined foliar applictaion of EDTA calcium @ 0.2 % with boric acid @ 0.1% during berry development and veraison stage was highly useful in reduction of berry cracking and shattering in grapes var. Muscat Hamburg.
Retention of 9 leaves above the last cluster along with preharvest spray of 0.2 ppm homobrassinolide during berry development stage coupled with GA3 application @ 10 ppm during pre bloom stage for rachis elongation enhanced the quality of bunches in grapes var. Muscat Hamburg.
Pruning severity at 7th bud level during summer season (May-June) month and 3rd bud level during winter season (December-January) in grapes var. Muscat Hamburg was found to be suitable for high yield and quality under double pruning double cropping system.
