Abstract
The article presents the results of a field experiment investigating the effect of different nitrogen application rates combined with the biostimulants “Gumimax” and “Fertiplant” on the formation of biometric parameters of winter wheat cultivar “Utkir.” Plant density, plant height, and leaf surface area were evaluated. It was established that the application of biostimulants against a background of moderate nitrogen rates (N180–N210 kg/ha) promotes the formation of a more productive
agrophytocenosis compared to higher nitrogen rates without biological regulation.
