The article is devoted to the growth and development of the corn root system at various norms of mineral fertilizers and biostimulants in the gray soils of Uzbekistan. The introduction of mineral fertilizers and biostimulants
“VL-77” and “Avangard Start” have a positive effect on the formation of the root system and the distribution of the root system in the arable and subsurface layers of the soil.
It was revealed that when applying fertilizers in the norms N180P120K90 and N250P175K125 kg/ha and the use of biostimulants, it stimulates the weight of the root system and above-ground organs.
It has been established that when applying fertilizers in the norm N250Р175К125 kg/ha and the biostimulator “VL-77”, the corn root system is located more in the arable soil layer. This contributes to a more efficient use of nutrients, and thus creates favorable conditions for the formation of a high yield of corn.
