Formation of soybean cultivars yield depending on the nutrition systems in the conditions of the eastern part of forest-steppe of Ukraine

The paper reports the results of the studies of different fertilizing backgrounds‟ influence on soybean seed yield. A close relationship between crop yield and the application of organic and mineral fertilizers on the organic background is established. The presented data show that a high seed yield of soybeans can be obtained by the application of manure at the rate o f 30 t ha-1 before soil treatment. At increasing the rate of mineral fertilizers on the organic background seed yield increase was not observed.
