Evaluation of the effectiveness of the use of physiologically active substances in pea seed production

In the article considers the effect of treatments with physiologically active substances (growth stimulants and biological products) on the sowing qualities of pea seeds, plant resistance to root rot, as well as their effect on plant productivity elements. The study was carried out on the basis of the laboratory of seed science and primary seed production of the FSBSI FNTs ZBK for a long time (from 2001 to 2022). Currently, about 120 plant growth regulators with one or more useful properties are registered in Russia. The drug Agat-25 in the form of a concentrated solution contains microorganisms, microelements and growth substances. Albit preparation contains a natural microbial polymer poly-beta-hydroxybutyric acid from soil bacteria Bacillus megaterium and Pseudomonas aureofaciens, a balanced set of macro- and microelements, coniferous extract, etc. Ambiol preparation is a synthetic plant growth and development regulator. The active substance of this drug is 2 methyl - 4 di-methyl-amino-methyl-benzymidazole - 5-ol-dihydrochloride. Biosil is a natural preparation intended for pre-sowing seed treatment and spraying of plants during the growing season. Biosil is a triterpene acid derived from plants with bactericidal and growth-promoting properties. Binoram is a seed disinfectant and fungicide for the treatment of vegetative plants with a growth-stimulating effect. Relict P is a modern environmentally friendly and safe preparation based on salts of humic and fulvic acids, which has growth-stimulating, adaptogenic and protective properties. seed treatment, as well as when spraying pea seed crops. The conducted studies have shown the high efficiency of biopreparations and plant growth regulators Agat - 25, Albit, Ambiol, Binoram, Biosil, Relikt R in pre-sowing seed treatment, as well as when spraying pea seed crops. The use of the above preparations provides a significant increase in the sowing qualities and yield properties of pea seeds while reducing the level of environmental pollution in comparison with the standard technology.
