LABOUR PRODUCTIVITY AND EFFICIENCY OF CRYSTAL VARIETY’ CULTIVATION IN THE DON REGION
New ways of doing and training of bushes were studied on noncovered vineyards in terms of the Lower Don region, in conjunction with ways of vine pruning and crop load. We proved the advantage of new ways of doing: zigzag cordon and Y-shaped, 2 stage placing of perennial vines on the trellis as well as a small cupshaped training on singlewire trellis which contributed to the increase of yield of vineyards, and reduce labor intensity of culture. We found out the effect of the way of vine pruning and bush load on the yield and quality of a crop.
