Abstract

Mid–season depression of grassland yield following spring application of N was found to be due almost entirely to clover depression, the grass fraction showing no after effects of the treatment. The effect became more marked and lasted longer in successive years. Varying the date of first defoliation in spring did not affect the clover depression significantly. Possible causes contributing to the depressing effect are discussed.
