Yield and Quality of Grapes at Different Load Rates

Abstract

The article presents research data on the de-pendence of the yield of vineyards and the quality of grapes on the load of shoots. The studies were carried out at the All-Russian Re-search Institute of Viticulture and Winemaking named after Ya.I. Potapenko, Novocherkassk, Rostov region. On grafted vineyards of the Krasnostop Zolotovsky variety, load rates were studied: 20; 25; 30; 35 shoots per bush. The conducted studies revealed: the maximum yield was obtained in plantings with a load of 35 shoots per plant and amounted to 5.78 t / ha with the best grape conditions in the experi-ment – the mass concentration of sugars in ber-ry juice was 284, and the titrated acids were 6.2 g/dm3.
