Abstract
The research was carried out to study the effect of biological preparations (Gribofit and Imunazot), applied both separately and together with nitrogen fertilizers (at the rate of 10 kg of NPPN. per 1 ton of straw) with the use of by-products as fertilizer on crop yield and productivity of the link of the cereal-row crop rotation “sunflower–barley-soybean”. The work was carried out in 2018-2020 in Kursk Region on typical slightly eroded heavy-loamy chernozem. The results are obtained for the following variants: 1. crushed by-products of crop rotation crops (control); 2. crushed by-products of crop rotation crops + nitrogen fertilizers at the rate of 10 kg of NPPN per 1 ton of cereal straw; 3. crushed by-products of crop rotation crops + biological preparations (Gribofit and Imunazot); 4. crushed by-products of crop rotation crops + biological preparations (Gribofit and Imunazot) + nitrogen fertilizers at the rate of 10 kg of NPPN per 1 ton of cereal straw. The results of the studies showed that the application of biological preparations against the background of surface embedded crop by-products provided an increase in the yield of all the crops of the crop rotation link in relation to the control. But higher efficiency was noted when using nitrogen fertilizers against the background of the applied crushed plant residues, it was 10.67 thousand grain units per 1ha, which exceeded the control by 3.19 thousand grain units per 1 ha (42.6%).
Highlights
The introduction of environmentally safe and economically sound crop cultivation technologies in modern agricultural production allows to increase the yield and quality of crop production [1], and minimize anthropogenic impact
Surface embedding of plant residues with biological preparations in the cereal-row crop link of the crop rotation provided an increase in the yield of oilseed sunflower in relation to the control, by 1.22 t/ha at LSD05 = 0.26 t/ha
The use of joint application of biological preparations with nitrogen fertilizers led to an increase in the yieldof sunflower, where the increase in relation to the control was 1.58 t/ha
Summary
The introduction of environmentally safe and economically sound crop cultivation technologies in modern agricultural production allows to increase the yield and quality of crop production [1], and minimize anthropogenic impact. In this regard, there is an increased interest in the methods of biologization of agriculture and resource conservation using biological plant protection products, growth regulators, by-products of crops as organic fertilizers and microbiological preparations of a wide spectrum of action [2, 3]. The use of biopreparations leads to an improvement in plant growth by reducing the stress effect on the plant of unfavorable environmental conditions, contributes to the most complete disclosure of the potential of the variety, which relates to both quantitative and qualitative indicators of agricultural products [6, 7], and proves the feasibility of treating straw with biopreparations before embedding it into the soil[8].
