Prorochenko T. Features of development and productivity of spring rape (Brassica napus f. annua D. C.) depending on the elements of growing technology in the Right-bank Forest-steppe

The dissertation is devoted to solving an important scientific problem of improving the elements of cultivation technology for the implementation of the biological potential of productivity of varieties and hybrids of rape rake in conditions of the Right Bank Forest-steppe of Ukraine. In the dissertation, elements of growing technology of spring rape varieties and hybrids for conditions of the Right Bank Forest-steppe of Ukraine were substantiated and first established by experimentally determining of optimal sowing methods, seeding rate and fertilizing. Complex influence of weather conditions, features of varieties and hybrids, seeding rates and sowing methods on photosynthetic activity of sowings in the process of vegetation is determined. Dependence of yield structure elements and qualitative indices of rape seed from growing technology elements was established. The obtained and generalized material on the basis of economic and energy analyzes makes it possible to recommend to the introduction into production in the conditions of the Right Bank Forest-steppe elements of cultivation technology, which will ensure the formation of yield of rape in a level of 3,5–4,0 t/ha.
