Kykalo M. Sugar beet productivity depending on elements of growing technology in conditions of Right-Bank Forest-Steppe of Ukraine

In the thesis are theoretical generalization and new solution of scientific problems - realization of sugar beet hybrids biological potential of Right-Bank Forest-steppe. Problem was solved by optimizing the seed preparation, size of sowing fractions and varietal composition. Using the aggregate results of the field research is provides 70-78 % seed germination, root crops yield - 40-50 t/ha, sugar content - 16-17 %, the yield of sugar - 7.0-8.0 t/ha. Use encapsulated, encrusted and pelleted seed in Right-bank Forest-steppe for sowing is provided the higher yields of root crops in 4.0; 2.1 and 1.2 t/ha, yield of sugar - 0,78; 0.37 and 0.19 t/ha respectively compared with the control. For identical growing conditions (especially the same stand density of plants per unit area) the yield of roots of triploid hybrids was in 11.7-13.1 %, yield of sugar - in 7.7-11.0 % higher than diploid hybrids. For sowing on final stand density with seeding rate of 7.1 pcs. /m of the sugar beet productivity, regardless of hybrid, decreased compared to the rate of sowing 8.6 pcs./m on 3.1-5.7 %.
