Abstract: Results of experience in the use of fertilizers under grain feed crops (barley, oats) in terms of the Tyumen region. In the period from 2006–2011. for an application of mineral fertilizers 1.5; 2,0; 2.5; 3.0 t/ha in bulk made respectively 79; 104; 131; 158 kg. the active ingredient of fertilizers per 1 ha. Fertilizers – ammoniac saltpeter (N-34 %) + diammofoska (N-10 %, 26 % P, 26 % K) were made prior to sowing in a ratio of 1: 2 locally recessing – 3,6 NWT. The purpose of the observations was to determine the optimal rate of mineral fertilizers needed to obtain the highest possible crop yield. The fertilizers were applied for barley Placed in zernoparovom zernotravjanogo and crop rotation, and oats, wheat is grown in the link zernotrav- janogo rotation. Yields of grain feed crops in the observation period remained stable; both rotation meet the requirements for their cultivation; barley yields provided 3,55–5,57 t/ha, oats – from 4,03 to 5,86 t/ ha. During the observations, it was noted that the average yield of barley by oats, was 10 % higher than the yield of barley for peas. Fertilizing a positive impact on the productivity of both cultures; the level of allowances in some years reached more than 1 ton / ha of grain. Each introduced into by kg.d.v.udobreny at an application rate in 2,0 ts/ha provided out of 3 to 12 kg barley, from 2 to 4.5 kg of oats. Barley is optimal application rate of fertilizer 2.0 t/ha, which achieves the greatest positive effect of their actions; grain output per 1kg.d.v fertilizer is 7 kg (average over 3 years). Oats require application rate of not less than 3,0 ts/ha, with her for the entire observation period was get the most out which ranged from 3.22 to 8,35 kg wheat from 1 kg.d.v. fertilizers.
Keywords: barley, oats, fertilizers, productivity, application rates, the impact of fertilizers.
