Kozina T. The certain elements improving white mustard cultivation technology in the western forest steppes conditions.

The thesis presents the research results characteristics of growth and development the white mustard seed training productivity depending on the varietal characteristics, sowing duration with using growth regulator "Vermybiomah" and seed rate and also seed quality indicators were defined, it was established the economic and energy evaluation technology for mustard white growing in the western forest steppe. On the basis of the field and laboratory researches and production inspection, and also purposely to maximize high quality yields in the western forest steppe were recommended: The Sowing of white mustard seeds, Pidpecheretska and Podolyanka varieties to do in early spring term at the thermal regime level of the soil at a depth of seeding 3- 4 oС with seeding rates 1,5-2,0 mln / ha of similar seeds, with the crops processing during the growing season of growth regulators "Vermybiomah" at a dose of 8 l / ha, which will provide yield at 2,28-2,55 t / ha.
