In long-term field trials the productivity, coexistence, persistency and dynamics of crude protein (CP) content of white clover grown in binary clover/grass swards in mixtures with 13 grass species have been studied on brown-lessive and sod-podzolic gleysolic soils of Latvia. The ratio of white clover to grass in mixture was 1:1. The utilization of a sward was 3 and 5 cuttings. Crude protein content in dry matter (DM) was determined between cuttings both for each two-component clower/grass sward and for each component in a sward. Experiments have shown that the productivity of white clover/grass and survival of white clover in a sward were greatly due to cenotic activity of grasses.
