Purpose: to determine the effect of soaking Jaguar pea seeds in a solution with biopreparations, such as “Biohumus Concentrate” and “Biohumate + 9 Microelements”, on the crop growth and development in various soils.
Materials and methods. Laboratory studies were conducted in 2024 at Federal Agricultural Kursk Research Center. Pea seeds were germinated in germination chambers of 100 pcs. for 4 and 8 days on various soils. Before germination, the seeds were pre-soaked for 24 h in tap water, in “Biohumus Concentrate” diluted with water at a dose of 10 ml of the preparation per 1 l of water, in “Biohumate + 9 Microelements” at a dose of 10 ml of the preparation per 1 l of water, then the results were compared with the control option without additional soaking.
Results. It was found that the maximum effect on plant height (5.8 cm) and root length (15.9 cm), wet (17.0 g) and dry (1.68 g) plant weight was observed when using the preparation “Biohumate + 9 Microelements” and the soil Terra Vita. Wet and dry weight of the roots of 100 plants was the highest when using the preparation “Biohumate + 9 Microelements” on all the studied soils (the increase relative to the control was 18.7–61.7 and 17.9–70.0 %, respectively). In all other experimental variants, no difference in the effectiveness of the biopreparations was found. With a decrease in soil fertility, seed germination and dry weight of roots decreased, but the amount of dry matter in pea roots increased. The wet weight of 100 roots of pea plants increased under the influence of biopreparations (r = 0.55, α = 0.05) and decreased with a decrease in soil fertility (r = –0.69, α = 0.05).
Conclusion. It was found that preliminary soaking of pea seeds of the Jaguar variety in a solution with biopreparations “Universal Biohumus Concentrate” and “Biohumate + 9 Microelements” for 1 day causes an increase in the germination energy of seeds, plant height, root length, wet and dry weight of plants and roots on all studied soils.
