Tall fescue S170 and Italian ryegrass S22, slow‐ and rapid‐establishing grasses, respectively, were sown either with white clover or with a mixture of red and white clovers, with or without a companion‐ or cover‐crop, and with or without nitrogen. Swards established without a cover‐crop were grazed frequently or cut infrequently; swards undersown with the oat crop were grazed once in the autumn. In the year of sowing tall fescue/clover mixtures produced yields similar to those of Italian ryegrass/clover swards. Tall fescue proved sensitive to competition, even from red clover, during establishment and sowing under a cover‐crop is therefore not recommended. The yield of red‐ and white‐clover was increased when sown under a cover‐crop and when cut infrequently, compared with frequent grazing by sheep. The growth of white clover was greatly reduced by adding red clover to the mixture, particularly under a cover‐crop and when defoliation was infrequent, but red clover increased total yield. The effect of N applied to the seed‐bed varied with the method of establishment. Cereal yield was reduced under dry conditions by undersowing with a mixture containing red clover.
