Tyshchenko M. Efficiency of sugar beet growing under different saturation and fertilization in grain-beet crop rotations in Left-Bank Forest-Steppe of Ukraine. Manuscript.

Object - the formation yield of sugar beets and other crops and changes of soil fertility depending on the share of beet sugar in sugar beet rotation. The aim was to establish patterns of change in the performance of different crop rotations sugar beet share of beet sugar, beet growing efficiency depending on the saturation of their rotation.Methods - field, laboratory, measurement, weight, quantity and weight, settlement and comparative, mathematical and statistical. Science-based theoretical and practical bases and recommendations for the concentration of sugar beet in crop rotation with a long rotation, efficient fertilization of sugar beet in crop rotation with a short rotation, which contributes to obtaining 40-45 t / ha of sugar beet, 7,0-7,5t / ha sugar. The main results of studies implemented in 2000-2009 and in 2011-2013 the farm Poltava region on a total area of 950 hectares. Use - agricultural production.
