Abstract
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
Highlights
In the Krasnoyarsk Territory, characterized by extreme climatic conditions, the issue of realizing the adaptive potential of grain crops is relevant
More than a million tons of harvested feed in the region is accounted for by haylage, of which 80 % is for grain production, which is based on grain feed crops [1, 2]
In 2018, there were no significant differences in barley varieties in comparison with the Biome control, the yield of green mass was from 3.26 t/ha for the Emelya variety to 3.62 t/ha for the Takmak variety
Summary
In the Krasnoyarsk Territory, characterized by extreme climatic conditions, the issue of realizing the adaptive potential of grain crops is relevant. Grain crops in this region are widely used for fodder purposes. More than a million tons of harvested feed in the region is accounted for by haylage, of which 80 % is for grain production, which is based on grain feed crops [1, 2]. An important role in realizing the adaptive potential of grain crops is the optimization of cultivation technology [3, 4]. An increase in the share of climate in the variability of grain crop productivity and the scope of yield variation was noted by A.
