The influence of different soil treatment on the yield coefficient of grapevine fruit buds was studied during a 3-year experiment. Muller-Thurgau grapevine variety and five soil treatments were used in this experiment. Grapevine bushes were planted at a 1 m distance in rows, with a distance of 3 m between rows. The growing form was a simple courtain. If the coefficient of grapevine fruit buds yield of variant T was estimated as 100%, the coefficients of other variants were as follows: M 123%, R 112%, P 105%, and N 94% respectively. The average (x) of all treatments variants was 106.8%. When testing the length and ripeness of 1-year old fruit wood, the longest shoots were found in variant P - 1452 mm (100.27%), followed by R - 1406 mm (97.09%), T - 1448 mm (100%), M - 1436 mm (99.17%), and N - 1316 mm (90.88%). Examination of damaged fruit buds revealed the following coefficients of damages: T - 100%, M - 124%, R - 127%, P - 136%, N - 109%, with the average of 119.2%. The best ripened rapevine wood (58.1% of total length) was observed in variant M whilst variant P showed the lowest ripeness (49.80% of total length)
