Osadchuk V. biological of feature and productivity of seed plants MS hybrids of sugar beet in dependence on conditions of cultivation in the central Forest steppe of Ukraine

In the dissertation results of researches of the author by definition of biological features and productivity of seed plants MS hybrids in dependence on conditions of cultivation in the central Forest steppe of Ukraine are stated: a local fertilization on stages of organofaction of seed plants, application nonconventional (green manure crops, a biohumus) fertilizers and an additional pollination. It fixed, that at cultivation of seeds MS hybrids local entering N20 and N25 accordingly at 6-th and 7-th stages of organofaction on a background of base fertilizer Р50К35 and 40 t/ha provides productivity of seeds and their quality at a level of a traditional fertilizer system. Opportunity of application of nonconventional fertilizers fixed also (green manure crops, a biohumus), alternative traditional. Theoretically proved and developed technology AP components MS hybrids. Thrice AP seed plants raises productivity of seeds on 2,0-4,3 c/ha, a germination on 7-13 %. In the biological attitude the most effective AP is in a flowering time of 40-50 % of seed plants compared with 20-30 % and 60-70 %.
