Patyk S. Efficiency is the shot field crop rotations in conditions of Steppe of Ukraine

On the basis of the results of long-term experimental researches influence the crop rotation factor on a water, nutritious mode and fitosanitar a condition of ground and crops is revealed. The importance of the vegetative rests in formation of stocks and balance of organic substance in ground is established. It is determined agrotechnical, economic and energy efficiency shot field crop rotations with various saturation, accommodation and a parity of grain and olive cultures, it is scientifically proved expediency of introduction of optimum variants of alternation of cultures for facilities of different specialization depending on ground-climatic conditions of Steppe of Ukraine. For reception of high and stable crops of agricultural crops it is recommended in shot field to place crop rotations high-yielding, highly productive grain, leguminous and olive cultures after the best predecessors: wheat winter - pair black and peas, barley winter and sunflower - wheat winter, and raps summer - peas and barleywinter.
