The studies were carried out on varieties of winter barley of intensive (Buran) and plastic (Osnova) types in field crop rotation, saturated with legumes, predecessors - peas and soy. In the tillering phase - the beginning of the phase of emergence into the tube, the plants were sprayed once with solutions of steroid glycosides Moldstim (MS) and Ecostim (ES) at a dose of 25 mg/l, in the control variant - with water. It is shown that the total (biological) yield of winter barley plants depends on the content of plastid pigments, the time and intensity of their work in all photosynthetic organs of plants (leaves, stems, ears). Processing plants with growth regulators leads to an increase in the chlorophyll content in plant organs, an increase in the parameters of the chlorophyll index by 1.3-3.9 times, especially when growing varieties for peas. Between the chlorophyll index and the productivity of varieties, a high correlation was found (r> 0.70).
