Abstract: Two-year experiments were conducted on two different soil types during 2021/22 and 2022/23 to study the impact of microbiological preparations, Mycor-FAZOS and Vitality-FAZOS, on the yield and quality elements of winter wheat cultivar Maja (Agrigenetics). The experiment was set up in a split-block design with four repetitions across two soil types, with 12 different variants on each soil type. The base plot area was 40 m2, and the effective plot area was 27 m2. The research factors included: A (soil type): A1 - gley soil; A2 - eutric cambisol; B (disease control): B1 - control; B2 - chemical pesticides; B3 - biopreparates (seed treatment + foliar treatment) and C (nitrogen fertilisation): C1 - based on soil analysis; C2 - 70% of recommended application. Variables included grain yield (t/ha), grain protein content (%), hectoliter weight (kg), and plant height (cm). The highest average grain yield was achieved with variant B3C2, with a 12.50% increase compared to variant B2C1. Differences between these variants included 6.0% for protein content, 5.97% for hectoliter weight, and 7.93% for plant height. It was observed that Mycor-FAZOS seed treatment promoted root development, resulting in healthier, taller, more robust plants with a more uniform growth and darker colour than untreated seed variants (indicating increased photosynthesis index). The protection achieved with Vitality-FAZOS biopreparations (fungicidal microorganisms synthesising growth hormones) ensured healthier wheat plants, leading to higher seed yield and better quality parameters.
