Efficiency of subsowing of a lucerne in old-age artificial herbage at different modesof its use in the conditions of Yakutia
The research was conducted in 2004-2016 in the research and production station located 70 km higher Yakutsk on a terrace above flood-plain of the Lena river. The experiment is put on grass stand of the seventh year of growth. The basis of the stand consisted of the herbs, sown in 1997: Psathyrostach...
