The prospects of creating adaptive self-regulating herbage mixtures and their longevity in the context of different methods of use were studied at the sites with cryogenic pale-yellow soil in Yakutia (Sakha Republic). We have used a six-component grass-legume mixture. Research results have showed that grass-legume mixtures intended for grazing provide high yields of feed crops (7.75 tons per year on average) at late sowing dates and the cutting height of 5 cm. The share of alfalfa in herbage mixtures is 61%. In pure batches of alfalfa and sweet clover, the maximum content of crude protein was 23.89% and 23.5%, fat content - 3.86% and 3.38%, respectively. In the pasture coenosis, organic matter content is the highest (up to 4.37%) at the cutting depth of 0-10 cm and 10-20 cm regardless the sowing period. [ABSTRACT FROM AUTHOR]
