When growing a winter barley on a black fallow the higher grain yield had a sort Tutankhamon (5.61 t/ha, with profitability 93,0 %) when was sown on October 2, on the predecessor of soy - when was sown on the 17-th and the 25-th of September (4.96 and 4 86 t/ha, with the profitability 71.6 and 68.5% respectively). At sowing of winter barley Dostoiniy of the two-rowed variety on the predecessor of soy the higher productivity was obtained with the norm of sowing 5.5 and 4.5 mln./ha (4.22 t/ha, with the profitability 41.2 and of 47.8 % respectively). Against the background of various norms of sowing when the density of stems after restoring of spring vegetation was 501-758 pieces per square meter, the underseeding did not give a positive result. The most expedient and economically warrant (the productivity increased by 39-75 %) was the underseeding of barley with the norm of 3.5 mln./ha, when the density of stems in spring was only 150-270 pieces per square meter.
