Rudnyk-Ivashchenko O. Mine process of formation of productivity of grain of millet sowing

Work is devoted definition of influence of elements of technology of cultiva-tion of verities of millet sowing on processes of photosynthetic activity in ontogene-sis plants, formation of efficiency and its qualitative indicators. It is stated results of researches on which generalisations features of formation of green pigments (chlorophyll) on growth phases and developments of plants for the first time are defined, dependence between the size of a sheet surface, the mainte-nance of a chlorophyll a and b in pure efficiency of photosynthesis of millet sowing is established. In the conditions of application of microcells the increase in quantity of a chlorophyll b in comparison with a chlorophyll a increases, that is the parity of a chlorophyll а/b becomes <3 - the chlorophyll maintenance b within grades Оlitan and Оmriyne fluctuates accordingly from 2,00 ± 0,05 to 2,33 ± 0,22 mg /dm2. On the basis of results of researches influence of conditions of cultivation on productivity, technological qualities of grain, photosynthetic activity various behind a genotype of verities of millet is shown: terms of sowing, a zone of cultivation, a dose of mineral fertilizers, entering of micro cells. Are defined optimum phоnes for vari-ous behind terms of maturing of varieties which provide high efficiency and quality of grain. So variants N90Р40K90 and N90+30Р40K90 are the best doses of mineral fertiliz-ers that increase the fiber maintenance in grain of millet sowing by 2,2-2,8 %. The variety role in technology of cultivation of millet sowing through defini-tion of ecological stability and plasticity of varieties of this culture is defined. As a result of studying of specific structure of weeds at crops of millet sowing and definitions races specific stability of plants the integrated system of protection of crops of millet sowing from harmful organisms is developed. With participation of the author new variety Оmriyne which essentially ex-ceeds existing national standards behind level of productivity, its stability, for the first time in Ukraine and the world, behind stability level to smut and behind parame-ters of technological and consumer properties of grouts is created. On the basis of the received results of long-term researches the concept of pro-tection of millet sowing from weeds is developed.
