Kalenych P. Optimization elements of the technology of production of high quality winter wheat seeds and their influence on crop quality in the right-bank Forest-steppe

The dissertation is devoted to the study of the influence of the elements of the technology of production of high quality winter wheat seeds and their influence on the seed quality in the conditions of the right forest-steppe and the substantiation of the most favorable terms and methods for seeding and seeding pomm seeding for varieties of new generation of winter wheat of the selection of the Institute of Plant Physiology and Genetics National Academy of Sciences of Ukraine, recommended for cultivation in the southern part right-bank forest-steppe of Ukraine, providing seeds with high sowing qualities at a high level of seed yield. Significant varieties distinguished between the varieties that were studied. The peculiarities of the formation of yield and seed quality of seeds depending on the terms and norms of sowing were studied. Separate elements of seed technology have been improved. Recommended accelerated breeding of wheat varieties of winter Bohdanа and Slavna spend with the seeding rate of seeds 2,5-3,0 million pcs./ha, and the varieties of Chorniava and Astarta are carried out with the seed seed rate 4,0 million pcs./ha, and if possible, seeding with the seed seed rate 5.5 million pcs./ha. It was established that the postpone of the sowing date on October 5 does not lead to a significant decrease in the yield of conditioned seed compared to sowing on September 15 and 25. The analysis of economic and energy efficiency of seed production according to different norms, methods and terms of sowing of investigated varieties of winter wheat has been carried out.
