Subject of research - short rotation crop rotation schemes with improved structure. Research methods - modeling of objects and processes in the field of stationary experiments , laboratory and field , statistical, data grouping , settlement and constructive method of ecological , economic and energy analysis . The results obtained are economic , energy , environmental and economic assessment of crop rotation structures in the 5-field rotations in three years rotation. Climatic conditions of the 2012-2013 growing seasons were unfavorable for winter grain , causing their yields were 1.4-1.8 times less compared to 2011 . High level of grain yield of maize was obtained in specific environments 2013 - 21,0-26,3 kg / ha, which is 41-46 % higher than in 2011-2012 . In 2013, the greatest yield was obtained sunflower - at 16,6-24,5 c / ha , depending on the variants of the experiment . Increase the proportion of fallow up to 20 % due to the same reduction in the proportion of green manure couple has a positive impact on the natural , energy and economic performance of crop rotations , but leads to increased deficits humus. The highest level of productivity of sunflower obtained in crop rotations with its saturation of 10%. Fertilizers increase the yield , yield energy crops , humus balance , but worsen the basic parameters of the economic efficiency of crop rotations due to reasons of high fertilizer prices and low growth of fertilizer major crop rotation.
