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.

Root knot nematodes, Meloidogyne spp. constitute one of the major important group of plant parasitic nematodes causing severe damage to both agricultural and horticultural crops. They are sedentary endoparasites and their parasitic life depends on the success to induce feeding sites in the roots of host plants (Perry and Moens, 2006). They are dispersed worldwide and parasitizes nearly every species of both cultivated and uncultivated plants. The four major species of Meloidogyne viz., M. incognita, M. javanica,M. arenariaand M. haplaare of immense economic importance because of their wide geographical distribution and wide host range (Perry et al., 2009). The most common species are
