Description
Red clover is the most important forage legume in Swedish ley farming (c. 500 tonnes of seed certified in 1986/87). It is traditionnally sown with a mixture of grasses, typically timothy and meadow fescue. Recommendations for maximum DM yields, obtained from extensive series of experiments, given no fertilizer nitrogen (Bengtsson, 1964; Arnemo and Steen, 1972) are 4-6 kg/ha red clover seeds ( of a diploid cul ti var) in a mixture of totally 20-24 kg/ha seeds sown. Red clover content in the established sward declines with time from c. 60 % in the firstyear crop to c. 25 % in the third-year crop (Ebbersten, 1974). In practice, contrary to the experimental situation, farmers often apply N-fertilizer due to the lack of persistency of the red clover. This may affect optimum seed mixture proportions. The present experiment was devised to investigate how Nfertilizer and different proportions of clover to grass affects DM yield and herbage quality in a cutting sward. This paper presents preliminary results on DM yields obtained from experiments in the southern part of Sweden.
