Bobrujko V. Optimization of elements of technology of growing hybrid seeds of sugar beet in the south-eastern part of Crimea

The thesis deals with the results of the author's investigations of optimization of elements of technology of growing seeds of MS hybrids of sugar beet in the south-eastern part of Crimea. The methods of formation of hybrid seed yield have been theoretically grounded and worked out, viz: seed rate, row width, ways of sowing, techniques of formation of high-yielding seed bearing plants. The thesis gives scientifically grounded proposals for production, namely: sowing with seed rate of 25-30 seeds/m and 12-15 seeds/m, mixed sowing with barley and row widths MSC - 45 cm, P - 75 cm and conducting additional pollination in the period of mass flowering which ensure the increase of seed yield by 0.2-0.4 t/ha, and of germination by 4-8 %, as compared with the present technology. In 2005-2006 the results of research were implemented on farms of Sovetsky and Dzankoy regions of ARC, every year on the area 30-40 ha. The annual economic effect amounted to 42,6-62,3 thousand UAH
