Bratinov I. Working art the complex of agronomic measures for increasing the productivity and quality of wine cultivars under the condition of the Southern Ukraine

The Dissertation is devoted to studying the influence complex of agrotechnical measures on the productivity of wine cultivars. The measures studied are: plantage renova-tion by different tools, root nutrition with nitroammophosca, irrigation, leaf nutrition by crystalon at different planting designes. The plantage plowing renovation in spring, root nutrition in rows in dependently upon planting desigucause deeper inflorescence differentiation, central buds fruitfulness coefficient after the primordial sum, over all the nodes studied; the quality of roots in-creases, in the soil layer from 20 up to80 cm. Under the action of agronomic measures the productivity of Chardonnay cultivar increases in the year of action by 2.6 - 3.5 t/hect, in the year of after-action - by 3.6 - 5.7 t/hect; for the Aligote cultivar 1.5 - 2.1 t/hect and 2.0 - 3.1 t/hect respectivery. The wine quality may be increased by crystalon on the back groud of measures complex mentioned above. The cjmplex worked out or its separate parts are applied in the are a of 122 hect. Thepure profit equals 202011 hrn. And from 1 hectare - 1655.8 hrn.
