Shevchenko T. Productivity of various biological forms of sugar beet as affected by foliar application of fertilizers and fungicides against foliar diseases.

The thesis presents research results of an experiment carried out in the Right Bank Forest-Steppe of Ukraine on productivity of various biological forms of sugar beet subjected to foliar application of fertilizers and fungicides against foliar diseases. The effect on plant growth and development, leaf surface formation, photosynthetic potential, yield and root quality parameters in sugar beet was established. Object of the study - the productivity of various biological forms of sugar beet subjected to foliar application of fertilizers and fungicides. Subject of the study - sugar beet hybrids Ivanovsko-Veselopodolskyy MC-84 (triploid), Umanskyi MC 90 (diploid), Belotserkovskyy MC 57 (triploid), microfertilizers, fungicides, methods of microfertilizers and fungicides application, yield and technical quality of sugar beet roots. As a result of the research, it is highly recommended to apply fungicides along with the foliar application of micro-fertilizers Nutrivant Plus Sugar Beet or ADOB Macro + Micro in order to intensity sugar beet plants growth and development during growing season as well as to increase yield and to improve root quality parameters. On the whole, foliar application of fertilizers both separately and combined with fungicides prevents leaf diseases occurrence resulting in improvement of sugar beet productivity indicators and root quality parameters.
