Standard indicators for requirement definition winter rye in elements of mineral food at cultivation on the meadow-chernozem soil in the forest-steppe of Western Siberia

In researches in the Omsk region on the meadow-chernozem soil it is established that application dusting of seeds of a winter rye salts of minerals has positive influence on efficiency of culture. For years of researches increase in a harvest of a winter rye from doses of microfertilizers between 0.37 and 0.50 t/hectare at a harvest (control was 4.36). When dusting seeds sulfates the dose of 100 g/c as for zinc, and copper is most effective. When dusting sulfate of zinc has got an average rise of a grain yield in four years of 0.48 t/hectare or 11.01 % to control, copper - 0.37 t/hectare or 8.49 %. The greatest efficiency at use of manganese in the dose of 50 g/c. The yield is 4.86 t/hectare is received that is 11.47 % higher, than on the background. In option with the greatest yield (Mn50) we have increasing in carrying out of nutritious elements by a unit of production in comparison with a background is observed. It should be noted the consumption of macroelements, manganese, copper increased in comparison with a background...
