| Summary: | The application of two-axis use on varieties of spring barley, wheat and triticale is considered. In the conditions of the forest-steppe of the Krasnoyarsk Territory, it is possible to obtain a second harvest in the form of grain with the repeated use of crops. The best varieties of grain crops for two-axis use were identified: barley - Zhikhar and Emelya, wheat - Rix, Triticale - Erythrospermum d. 94/11-19. With two cuts (grain + green mass), the energy productivity of the Zhikhar variety was 32,2 GJ/ha, the Emelya variety-33.7 GJ/ha, the Riks variety-63.4 GJ/ha, the Erythrospermum d variety. 94/11-19 – 60,3 GJ/ha. By the control of one mowing, the energy productivity of the Zhikhar and Emelya varieties was 122,9 % and 97,1 %, the energy productivity of the Riks and Erythrospermum varieties 94/11-19 – 197,5 % and 182,2 %. An increase in the protein content in the grain of barley, wheat and triticale with two-mowing use by 0.2-3.9% was noted.here
