Продуктивность и качество зерна озимого ячменя в зависимости от действия регуляторов роста стероидной природы

Abstract

It was established an increase in fresh and dry biomass quantity, as well as an increase in the parameters of crop yield and yield components under the treatment of winter barley with growth regulators. The quality of barley kernels was improved through accumulation of proteins, starch, lipids and diminishing the content of cellulose and ashes. The efficiency of administrated growth regulators increases upon their application in the phases of tillering – beginning of booting stage and depends on variety peculiarities and precursor used.
