The article examines the dependence of the yield indicators of wine varieties of grapes on the load on the vine. Low or excessive loading of the tubers has been found to adversely affect the subsequent growth and development of the tubers. In the variant with a load of 80 buds in the Maysky cherniy variety, the highest number of buds was recorded - 65.5%. In the Bayan Shirey variety, the number of buds that grew when the load was 80 was the highest - 74.1%, while when the load was increased (120 and 160) it was 68.2 and 59.5%, respectively.
