Fostolovich V. Improvement of growing technologies of spring vetch for grain in the conditions of the central Forest-steppe of Ukraine

The object – processes of growing, development and forming of symbiotic, photosynthetic and grain productivity of spring vetch, depending on the term of sowing and the density of crops. The aim – to improve the technology of growing of spring vetch in the conditions of the central Forest-Steppe zone in Ukraine; the methods – common (field, laboratory – analytic, visual, weight) special (physiological), biochemical, thermostatic-weight and calculated, statistical methods: dispersional, correlative-regressive, comparative-calculated; novelty – for the first time in the conditions of the central Forrest-Steppe zone in Ukraine the dependence of forming of productivity and spring vetch grain quality from the term of sowing and the density of crops was established; the results – the influence of the term of sowing and the density of crops on the process of growing, development and forming of productivity, quality and biochemical indices of spring vetch grain was established; profiled specificity of forming of photo synthetic and symbiotic productivity of spring vetch in dependence on the term of sowing and the density of crops was studied; the economic and bioenergetic estimation of the growing technology of different sorts of sprig vetch on grain, depending on the term of sowing and the density of crops was carried out; introduction – in the farms PF "Yukhymivske" and "Bokhonytske" Vinnytsya region; the branch – Agriculture.
