INFLUENCE OF GROWING CONDITIONS AND SHOOT LOAD RATE ON GROWTH AND DEVELOPMENT OF SIBIR`KOVIY VINE VARIETY

The paper presents research data on the colle-ration of vineyards’ yield and quality of grapes on the shoot load. The research was conducted at the All-Russian Research Institute of Viticul-ture and Winemaking named after Ya.I. Potapenko, Novocherkassk, Rostov region. On grafted vineyards of Sibirkoviy variety, load norms were studied: 25; 30; 35; 40 shoots per bush. In different conditions (Pukhlyakov exper-imental field department and Novocherkassk experimental field department), the influence of growth place on development, fruiting and vigor of the grape plant was studied. The conducted studies revealed: the maximum yield was ob-tained in plantings with a load of 40 shoots per plant and amounted to 12.9 t/ha with the best grape conditions in the experiment: the mass concentration of sugars in berry juice was 19.6 g/100 cm3, and titrated acids 6.3 g/dm3. In Novocherkassk experimental field department, the yield was higher relative to Pukhlyakovsky experimental field department by 2.9 t/ha, but with lower conditions.
