In course of the research there was studied Japanese millet (Echinochloa frumentacea) herbage yield and indices of biochemical composition in dependence on sowing terms and seeding rates. The research was realized in the conditions of the Republic of Belarus in Grodno region on sod-podzolic sandy loam soils in 2008-2011. As a result of realized research there was revealed that the optimal parameters of the indicated indices of Japanese millet were obtained in the first sowing term at sowing rate of 5 million germinable seeds per 1 ha. According to the content of dry matter and crude protein in the green mass of Japanese millet sowing in mid-May before planting had the advantage in the third. The highest value of the dry matter content was obtained by seeding rate of 4.0 million (26.0%) and crude protein 5.0 million viable seeds per 1 ha (12%). The dry matter content in the green mass of Japanese millet increased the phase of stem elongation to lactic ripeness on 15.6-16.5%. At a later date it happened sowing down 0.9-5.8%. At the stage of milk ripeness dry matter content was greater with seeding rate of 3.0 million viable seeds per 1 ha, while increasing the seeding rate to 5.0 million viable seeds per 1 ha it was lower by 2.6% in the second and 3.7% - at the first terms of seeding.
