An agrobiological and techno-logical study of the Pamid grape variety was carried out during the realization of different variants of loading with winter eyes during pruning. An agrobio-logical and technological study of the Pamid grape variety was carried out during the realiza-tion of different loading variants with winter eyes during pruning. It has been established that the phenophases of development during the vegetation period occur and take place al-most simultaneously in the same time periods, and the grapes ripen during the first ten days of September. With the increase in the number of knots of a vine and with their lengthening, there is a well-defined tendency of reducing the percentage of developed winter eyes, fruit-ing shoots, weight per 1 cluster, less of reduc-ing the fertility rate. The vines grow well under the pruning loads of the four variants and the grapes manage to ripen. The best combination of sugar and titratable acid content for wine production is in the grapes from the variants with a load of 6 and 7 knots of a vine. The number of knots has a proven strong or moder-ate negative effect on the percentage of devel-oped eyes, fruiting shoots, bunches, fertility rate, weight of one cluster and 100 grains, dur-ing both years of the study. The increase in the number of knots is in a moderate, positive cor-relation with the yield of one vine.
