In course of the four-year research there was studied the organization of green and feed conveyor operating on the base of perennial leguminous and cereal grasses sowing in pure and cereal-leguminous mixtures. The research was realized in the conditions of the Republic of Belarus on the experimental field of Belarus State Academy of Agriculture in 2003-2011. The terms and duration of the use of grass species and grass stands by development phases depending on plant chemical content was determined. As a result of realized research it was revealed that the reduction of crude protein content and the increase of cellulose content in plants with different ripening occurred differentially with aging. Growing season length and cutting periods of perennials, productivity change of perennials at intensive 3-cutting use in relation to 2-cutting use were presented. The data of the beginning of vegetation period, average monthly temperature for April – May and the beginning of the first cut in the research years were shown.
