Abstract

Results from an experiment in which rye was sown in permanent grassland appeared to indicate that the growth of the rye was limited by lack of N. In further trials, rye was drilled at 200 kg seed/ha in rows 20 cm apart into a sward of permanent grassland on (a) 1 or (b) 24 Oct. 1959. Plots with and without rye were mown on 22 Oct., given 30 kg N/ha on 1 April 1960, and mown again on 20 April. Yields of dry matter in kg/ha on 20 April without rye were (a) 1630, (b) 1360, and with rye (a) 2900, (b) 2250, of which rye contributed (a) 950, (b) 600. On plots oversown with rye, the grass grew more upright so that about 300 kg dry matter/ha less grass remained on the plots after mowing than on those without rye. On one of the plots, where the yield of rye was low, the rye appeared to be suffering from N-deficiency, but not the grass.
