Abstract
Grape is one among the most delicious, refreshing and nourishing fruits of the world. It is one of the earliest fruits grown by man. The berries are a good source of sugars and minerals like Ca, Mg, Fe, and vitamins like B1, B2, and C. Grape has so many uses and is so unique that no fruit can challenge their superiority. Crop load is the most important factor affecting yield and cluster quality as well as vine vigor of both seeded and seedless varieties. Hence, an optimum canopy size and bunch number per vine are to be maintained for achieving better fruit Quality which warrants proper balancing between vigour and capacity. The pruning requirement of different varieties differs as per their growth behaviour. Therefore, variety-specific standardization of pruning is essential for any grape cultivars for harnessing potential yield and quality. In this view, it is essential to get scientific information on the pruning requirement of grapes. Pruning all the matured canes to fruit bud level, as adopted by local grape growers results in more exploitation of reserved food material leading to loss of vigour, quality and early setting of senility in vines. Heavy bearing of vines results in poor quality fruits with low TSS and high fruit acidity.
Highlights
Pruning is the most important cultural practice in the management of grapevine to sustain production and productivity
Canopy, vigour and productivity can be balanced through pruning levels
(1992) suggested that equilibrium of crop load versus vegetative development is important for production of quality fruits
Summary
Pruning is the most important cultural practice in the management of grapevine to sustain production and productivity. Effect of pruning severity on yield parameters Bunch traits Kumar and Tomer (1978) retained 60 buds on each vine in ‘Himrod’ grape and revealed that 5 buds with 12 canes pruning gave the maximum bunch weight (237.69 g) as compared to 6 buds with 10 canes (204.50 g). Sehrawat et al (1998) observed that the severity of pruning lowered the leaf per bunch ratio and bunch weight while yield increased with increasing number of buds per cane. The vines pruned Up to 2 buds per spur showed the highest TSS: acid ratio (24.70) as compared to a vine pruned Up to 6 buds per cane (18.18).Thatai et al (1987) observed that in cv. Terence (2008) examined the effect of pruning level and canopy division on yield, vegetative growth and fruit characteristics in Concord grapes and found that the season had a greater effect on titratable acidity and declined from veraison to harvest
