In India, majority of the area under grape were established on own roots with few vineyards on rootstocks. With the increase in problems in a period of time, the soils used for grape cultivation became saline with high contents of chlorides. Presence of these conditions resulted into the alt injury to the grapevine and the ultimate effect is rapid reduction in the yield. To overcome the problem of these adverse situations, growing of grape vineyards on rootstock became mandatory. Selection of cuttings, multiplication and supply of rooted plants to the needy growers can meet the demand. At present the growers are using different rootstocks viz., Dogridge, Salt Creek, St. George and Ramsey among which Dogridge rootstock is widely used. Other than these rootstocks, 110R, 1103P and SO4 are some of the rootstock that has got more importance in grape cultivation due to the salinity and drought problem.
Standardization of season, concentration, cane diameter, planting media will be done during the course of study.
Total outlay: Rs. 23.42 lakhs
