| Popis: | The modern concept of resource-saving technology for the cultivation of agricultural crops, including wheat, is based on the use of growth-stimulating biologically active substances and beneficial microorganisms. Studies aimed at the development of polyfunctional compositions that reduce the harmfulness of pathogens and have a positive effect on the production process are especially promising. The paper provides data on the biological substantiation of the use of polyfunctional complexes based on B. subtilis strains and chitosan salicylate to protect wheat from diseases and increase yields. Polyfunctional complexes “Vitaplan, KZh + 0.1% chitosan salicylate” (submerged cultivation, composition) optimize the physiological state of wheat plants; significantly increase its productivity and disease resistance. It was shown that the combined use of Vitaplan, KZh and 0.1% chitosan salicylate increased wheat productivity and the biological efficiency of the polyfunctional complex against wheat yellow rust. The use of the complex did not have a significant effect on the indicators characterizing the growth of the vegetative mass of plants, but had a positive effect on the structure of wheat yield. |
