dc.abstract.enAt present, there is growing consumer interest in Triticum spelta L., which has high nutritional value. This species is recommended for cultivation in organic farming. In this system of agriculture, biofertilizers are an alternative to mineral fertilization. Biofertilizers stimulate plant growth by providing nutrients through the biological fixation of molecular nitrogen from the air or by increasing the availability of insoluble nutrients in the soil and by synthesizing substances that stimulate plant growth. Green manure biomass and root secretions provide growth material for soil microorganisms, and microorganisms return nutrients to the soil and plants through nutrient decomposition and conversion. Considering the many benefits of using biofertilizers and growing cereals with cover crops for green manure in cereal rotations, field research was carried out on an organic farm to evaluate the soil microbes and the amount of biomass from green manures and their follow-up effect on Triticum spelta L. yields using biofertilizers. Two factors were researched: (I) biofertilizers: control object (no biofertilizer), Azotobacter chroococcum + Azospirillum lipoferum Br 17, Arthrobacter agilis + Bacillus megaterium var. phosphaticum, and combined application of atmospheric nitrogen-fixing bacteria with phosphate solubilizing bacteria; (II) green manures: control object (no green manure application), Trifolium pratense L., Trifolium pratense L. + Lolium multiflorum L., and Lolium multiflorum L. The results show that the most favorable abundance of microorganisms determined in the soil after harvesting Hordeum vulgare L. was recorded after the application of biofertilizers containing atmospheric nitrogen-fixing bacteria with phosphate-solubilizing bacteria under a mixture of Trifolium pratense L. with Lolium multiflorum L. Plowing green manure from a mixture of Trifolium pratense L. with Lolium multiflorum L. resulted in an average increase of 39% in grain yield of Triticum spelta L., while the application of a biofertilizer containing Azotobacter chroococcum + Azospirillum lipoferum Br 17 + Arthrobacter agilis + Bacillus megaterium var. phosphaticum resulted in an average increase of 63%. The proposed spelt wheat cultivation technique can be recommended for agricultural practice due to the positive response of grain yield, but it may also be an important direction for further research to reduce the negative impact of agriculture on the environment.
