Development of a biosubstrate as a growth stimulator for growing organic types of agricultural crops

Abstract

Environmental pollution, the energy intensity of the production of mineral fertilizers,
and the consequences of the globalization of the economy have led to the search for alternative farming
systems focused on the biologization of agriculture, the development of environmentally friendly
technologies for the cultivation of agricultural crops based on the use of modern forms of organic and
bacterial fertilizers.
A comprehensive solution to the problem of maintaining the balance of nutrients in the soil is the
use of bioorganic fertilizers that combine the ability to improve the mineral nutrition of plants, fixation
of atmospheric nitrogen, as well as stimulate the growth and development of plants. In this paper, the
growth-stimulating effect of biosubstrate on seeds of organic agricultural crops such as wheat, lentils,
peas, and buckwheat is investigated. The object of research was a biosubstrate consisting of a
biopreparation (Saccharomyces cerevisiae Z4 YRKM 0843, Lactobacillus casei 12/2C B-RKM 0844,
Streptomyces collinus P1 Ac-RKM 0845) and cattle manure effluents. During laboratory research, the
growth-stimulating effect of the biosubstrate on seed germination and their growth indicators was
established. Namely, a 10% and 50% solution of the biosubstrate improved the germination and
germination of seeds of agricultural plants more than a 25% solution. This biosubstrate can be
recommended as an environmentally safe growth stimulator when growing organic types of
agricultural plants.
Thus, the use of bio-organic fertilizers based on growth-stimulating microorganisms in the
cultivation of various crops reduces the chemical load on ecosystems and also leads to an increase in
yields and the quality of environmentally friendly agricultural products.
