The impact of growth regulators on grape varieties in the Urals

The article presents data on the effectiveness of the use of drugs on the structural components of the productivity of grape varieties. Research objects of growth regulators are Zircon and Mival Agro. Tests were carried out on table grape varieties Arkadia and Kodryanka. The same cultivars without treatment served as control. In the experiment with the use of Mival Agro the maximum indicator of the average bunch weight of the Arkadia variety was higher by 28.0% in comparison with the control, for the Kodryanka variety the indicator increased by 30.2%. In terms of productivity in the bush in the Arkadia variety the increase was 70.8%, in the Kodryanka grape variety it was 77.5% higher than the control variant when exposed to a similar preparation. Processing of experimental bushes in the variant Mival Agro showed the maximum increase in yield per hectare in the variety Arkadia by 70.0 %, in the variety Kodryanka by 78.1 % in comparison with the control option. Growth regulators have a positive effect on the productivity and yield of grape varieties, the most significant indicators are in the variants of the experiment with the use of the drug Mival - Agro
