The article highlights the questions of preliminary determination of the yield of vineyards, grape harvest prediction method to determine the optimal length of fruit cutting of shoots and load bushes wintering eyes, kidneys examined productivity index wintering buds (CP), which shows how many inflorescences have an average for each left eye escape when cutting to length, including the dead. It was found that the yield of grapes has a great influence the degree of differentiation of inflorescence of rudiments in the central buds overwintering buds. From the moment of laying the harvest of grapes in hibernating little eyes in the form of embryonic inflorescences until commercial harvest takes two growing seasons. During this period the generative organs of grape plants are affected by many factors of the environment. Heterogeneity was found of buds along the length of one-year matured shoots. It is expressed in the fact that many grape varieties fruitfulness buds at the base of the shoot are much lower compared with upstream eyes. A certain death of wintering buds (primarily, the main kidney) at the end of the growing season, before the autumn frosts. The main reason for the death of buds during the growing season - from defeat fungal diseases. Taking into account the percentage of deaths of buds proposed a new exponent forming embryonic kidney main inflorescence - productivity index of buds by the ratio of embryonic stems to the number of buds, including th
e dead. Thus, annual forecasting of grape harvest next year to cutting the bushes by the proposed method makes it possible to scientifically establish the optimal cut length of shoots and fruit load on the bush eyes. This helps to realize directly the potential of each variety and vineyard site and get maximum yields even in years with low fruit tab formations
