Marchuk A. Productivity of sorghum sugar depending on growing technology elements

The thesis presents the results of research on the characteristics of growth and development of different varieties and hybrid sorghum sugar depending on the doses of fertilizers and methods of controlling the number of weed control.Object research - processes of formation of productivity and quality sorghum sugar by determining patterns of growth and development of plants depending using.Subject elements of technology research - an element of technology of cultivation of sugar sorghum, their optimization based on the study of biological and agrophysical properties plant.Research novelty of the results of the research was that in a Right-Bank Ukraine improved forest-steppe number of elements of technology of cultivation of sugar sorghum. In particular, for the first time the influence of growing technology elements sorghum sugar to hydrocarbon feedstock composition and its performance for biofuels established varieties and hybrid sorghum sugar, the most suitable for the production of biofuels, optimized dose of fertilization reasonably optimal number of measures controlling weeds in crops of sorghum sugar.Also improved technology of growing sorghum sugar in terms of Right-Bank Forest-Steppe Ukraine by introducing Favorite varieties, using doses N80P80K80 fertilization using chemical methods to control the number of weeds - Super Dialen (1.0 - 1.25 l / ha in the phase of 3-5 leaves culture ).Became further development of the management of processes of formation of high yields of sorghum and technological qualities of sugar, depending on the technology elements growing.Installed that the use of herbicides (Super Dialen) for controlling weed-infested crops yield increases against the backdrop of sugar sorghum N80P80K80 43% on background N160P160K160 57%. The best yields were above-ground biomass varieties Favorites (54,7-114,5 t / ha), Nectarniu (42,4-103,1) and hybrid Medoviu (41,2-93,3 t / ha). Mechanical protection of crops from weers allows you to collect total sugars 4,91-8,75 t / ha, in embodiments using herbicides - 5,36-10,37 t / ha.
