Burdyga V. Formiong grained sorghum efficiency and soryz depending on terms and sowing methods under conditions of Forest-Steppe western

The object of the study - the processes of formation of productive properties of the examined varieties of grain sorghum and soriz depending from the period and method of sowing. The purpose of the work is to create conditions for the full agroproduction process in plants and grain sorghum and soriz in the forest-steppe of western by optimizing the timing and method of sowing. Research methods: induction and deduction (analysis and synthesis of research results ) , analogies ( a comparison between varieties , timing and method of sowing ) , generalization ( conclusions and recommendations) and special: field - watching the growth and development plants during the growing season , yield formation , laboratory - determination of the chemical composition and grain sowing qualities , mathematically -statistical - of variance, correlation, regression, cluster analysis - assessment of the reliability of the experimental data, calculation and comparison - determining yields, the conditional release of crude protein and starch assess the significance of the criteria and purpose of grain, economic and energy evaluation of the studied elements of the technology and determine their level of competitiveness. The gien thesis presents the results of researches in studies of features in of growth, development and forming productivity of grained sorghum varieties depending on terms and sowing methods under the conditions of Forest-Steppe western, as well as, there was given economic, bioenergetic value and technology evaluation on competitiveness. As it was established among the experiment variants, the best was grain sorghum sowing of Genicheske 209 and soryz Perlyna variety at average terms and daily temperatures of soil +12-14°C with row width in 45 sm, that provides the productivity of high-quality grain at the level 6,7 and 5,8 tonnes per hectare with the level of profitability of 104,5 and 80,5 %. The main results of research have been implemented in various forms of ownership agroformations during 2011-2012 years with a total area of 81 hectares. Sphere of use - agriculture.
