Modern crop cultivation technologies use biological products with adaptogenic and biofungicidal properties. The article studies the influence of Streptomyces sp on the growth, development, and formation of buckwheat crops. The treatment of seeds with biological products reduces field germination; however, their environmental sustainability increases. The maximum grain yield of 249.7 g/m2 was obtained when applying actinomycetes in the amount of 2.0 l per ton of seeds. The ability of the biological product to preserve the activity of nodes and shoots increased the number of inflorescences. The dynamics of biosynthesis and the fractional composition of chlorophyll in the leaves were studied. The biosynthesis of pigments was the most intensive during during seed treatment with Streptomyces sp in the amount of 1.0 to 1.5 l/t of seeds. The relative amount of chlorophyll “a” to chlorophyll “b” during the intensive development and mass flowering was relatively stable (2.5 ... 2.7). In the phase of fruit formation, in the control plants and plants treated with Rizoplan and actinomycetes (0.5 l/t), the proportion of chlorophyll b increased. In variants with a lower proportion of chlorophyll “b”, the seed productivity of plants was higher.
