Productivity and feed value of annual grass mixtures at different harvesting times in the Kamchatka Territory

The article presents data on the comparative assessment of fodder grass mixtures. A significant excess of the yield of the green mass of grass mixtures over the control variants (oats and barley) was revealed in the phase of entering the grain tube by 129,7–69,0% and 101,5–60,9%, respectively, in the earing phase by 33,5–127,7%. At the same time, the yield of green mass was in the range of 65,3–88,7 c/ha and 133,5–220,0 c/ha. In the phase of earing and milky ripeness of cereals, the protein content decreased to 8,0–11,0%, with the exception of oats + oilseed radish, where the protein was 14,19%. Rational timing of harvesting feed mixtures – exit into the tube, according to some options – earing of cereals (oats, barley).
