In this paper, the <br>growth-stimulating effect of biosubstrate on seeds of organic agricultural crops such as wheat, lentils, <br>peas, and buckwheat is investigated. The object of research was a biosubstrate consisting of a <br>biopreparation (Saccharomyces cerevisiae Z4 YRKM 0843, Lactobacillus casei 12/2C B-RKM 0844, <br>Streptomyces collinus P1 Ac-RKM 0845) and cattle manure effluents. During laboratory research, the <br>growth-stimulating effect of the biosubstrate on seed germination and their growth indicators was <br>established. Namely, a 10% and 50% solution of the biosubstrate improved the germination and <br>germination of seeds of agricultural plants more than a 25% solution. This biosubstrate can be <br>recommended as an environmentally safe growth stimulator when growing organic types of <br>agricultural plants. <br>Thus, the use of bio-organic fertilizers based on growth-stimulating microorganisms in the <br>cultivation of various crops reduces the chemical load on ecosystems and also leads to an increase in <br>yields and the quality of environmentally friendly agricultural products.</p> ER -
