Effect of Pruning Severity on Vegetative, Physiological, Yield and Quality Attributes in Grape
Pruning is the most important cultural practice
in the management of grapevine to sustain production and productivity. Pruning
methods have been developed to balance fruit productivity, vegetative growth
and attain maximum yield without reducing vine vigour. An increase in the
severity of pruning will increase the vigour of individual shoot at the expense
of total growth and crop (Weaver, 1976 and Celik et al., 1998).
Pruning the vines for optimum cropping
according to the vigour is the most reliable method to maintain balance between
growth and production. The vine should carry moderate number of canes in order
to maintain the uniform vigour throughout its life span. So, canopy, vigour and
productivity can be balanced through pruning levels. Eynard and Gay (1992)
suggested that equilibrium of crop load versus vegetative development is
important for production of quality fruits. Hence, it was felt necessary to
study the effect of different pruning severities of any grape cultivars for
their performance in newer climatic conditions.
