In the years 1992-1994 the yield and some qualitative characteristics of amaranth (Amaranthus mantegazzianus L. variety Elbrus) which was cultivated after winter intercrop triticale (variety Dagro), were investigated. There was found highly significant dependence of dry matter yield on atmospherical conditions as well as on row spacing. The herbage yields ranged from 3.79 to 8.54 tons of dry matter per ha in experimental years. At the equal number of plants (400 000 plants per hectar), the higher average yield was obtained with narrower row spacing (6.77 tons of dry matter per ha under row spacing of 0.375 m in comparison to 6.20 tons of dry matter per ha under row spacing of 0.500 m). The highest daily increments both of plant hight and aboveground biomass were found out in the second month of the growing season of amaranth (between the 40th - 60th day). The young plants of amaranth had high content of crude protein and aminoacids. During amaranth ontogenesis their content was being reduced, while the fibre content was increasing at the same time
