Abstract
Relevance. For the development of the main branch of agriculture in Yakutia — animal husbandry, one of the most pressing problems is the availability of feed. The article presents the results of research conducted at the Yakut Research Institute of Agriculture.
Methods. Scientific research on the selection of sunflower mixtures with promising forage crops was carried out at site 30 “A“(on the basis of the laboratory of feed production of the YANIISKH) on the second over-floodplain terrace of the Lena River in 2018-2019.
Results. The results of research on the growth and development of forage crops, the formation of yield, chemical composition and nutritional value of sunflower and its mixtures with promising annual crops are presented. High indicators for the development and yield of the tested crops were provided by sunflower mixed with corn 42.7 t/ha of green mass and sunflower mixed with Sudan grass 40.2 t/ha of green mass. The terms of sowing and harvesting of sunflower and its mixtures on permafrost soils are determined — sowing — the first decade of June, harvesting-the second decade of August before early-autumn frosts in the phase of mass flowering and throwing out panicles of the tested forage crops.
