For preparation of forages of farm animals generally 2 or 3 cultures are used. As a result of the productivity of animals sharply decreases. Investigation and the accelerated introduction of highly productive forage crops, new types and grades are necessary for successful development evidence-based system of a forage production allowing to intensify animal husbandry in Krasnoyarsk region. Researches on studying and adaptability of cultivation of rare forage crops (including crops terms) were carried out in 2012-2014 in a forest-steppe zone of Krasnoyarsk region, for the purpose of selection of sorts and plant varieties with creation of real opportunities of increasing the efficiency of forage crops at lower economic, labor and power expenses. Agrotechnology in experiences was standard, the cultivation zone was chosen for one-year forage crops. The laying of experiences and observations during plants vegetation were made according to methodical recommendations of All-union scientific research institute of forages (1983). Statistical processing of experimental data was carried out by the method of the dispersive and correlation analysis (Dospekhov, 1985), energy assessment was according to recommendations (Grigoryev, 1992). As a result of researches advantages of such cultures as barnyard millet, sorghum sugar and an amaranth, in comparison with oats were established (control). The productivity of green material was made to 504-460 c/hectare at the 1st term of crops and 533-517 c/hectare was at the second term. In control option (oats fodder )it was only 284 and 345 c/hectare respectively.
