The role of biological nitrogen in the barley grain quality under the conditions of long-term use of fertilizers and inoculation of seeds in the southern forest-steppe of Western Siberia

In the agro-industrial sector eq обеспечивает economy akad of many eq countries удобренном around the world, by the end of 20th eq удобренном century колмаков, one of the rational ways of eq agrocenozov development was the introduction of biologic eq внесение preparations vozdelyvanii intro eq land-use расхн practice. It,´s necessary to eq агрохимические estimate состава the contribution of biologic eq верниченко nitrogen to the formation of qualitative eq ehtyudy grain роста barley the eq reduction удобрений or replacement of chemicals [eq фосфора Zavalin priemov, 2005; Voronkova, 2011]. The eq drug hospital, on the sidelines of the field eq biologic experiment southern, located in the eq North-Western southern outskirts of the Omsk eq внесение city usloviyah and natural zoning eq изучаемых refers to the southern forest-steppe. eq засушливого Long-term ресурсы (over 25 eq years минеральные) patient experiences eq корчагина with примечание the use of mineral fertilizers, eq основе straw and bacterial preparate eq среднем associative гамзикова nitrogen feq ixation инокуляция showed increased eq путем protein puti content in the production and eq associative harvesting per hectare was 2.7 % and 0.15 t/ha eq зерна respectively новосиб compared to eq control вариантах. The use of mineral fertilizers eq novosib either последействие separately or together eq зависимости with the addition of straw had a eq инокуляции positive гектара effect on eq grain использование quality. In the options N18P42 and N18P42+ eq пшеницы straw минеральных protein content eq биологизации increased by 1.2 and 1.1 % compared to the control. The use of inoculation as a separate application increased the grain protein content 1.2-1.5 %. Studies have shown the possibility of regulating the receipt of biological (atmospheric) nitrogen into the agro-ecosystem. Experimentally proved nitrogen-fixing ability of the drug risogrin, which is apparently associated with survival in the chernozem soil deposited strains of microorganisms and their resistance to hydrothermal conditions of the vegetation period. Maximum rate of nitrogen fixation (proportion of atmospheric nitrogen in the total nitrogen of the biomass) was obtained in the variant of application of bacterial fertilizers in combination with straw. On average over the three years, the ratio of nitrogen fixation reached 13 %. Application of the biopreparation rizoagrin in agricultural production made it possible to increase the nitrogen fixation coefficient to 27 %.
