The influence of growth regulators and type of predecessor on the productivity and quality of winter barley

Abstract

The investigations were carried out on the varieties of winter barley Buran (intensive type) and the Osnova (plastic type), growing in pea and soybean, under conditions of field small-scale experiment. In the phase of mowing - the beginning of the exit into the tube, the plants were sprayed once with solutions of steroid glycoside preparations Moldstim (MS) and Ekostim (ES) at a dose of 25 mg/l, in control variants - with water. During the vegetative period, the parameters of growth and photosynthetic activity of plants were determined, at the end of vegetation - indicators of productivity elements, potential yield and chemical composition of the grain.
