Abstract
An experiment to determine the effect of applying high levels of N on the seed yield of S37 cocksfoot is described. Increasing the rate of application in the range 174–1044 Ib N/ac/annum did not substantially increase yield, except where 1044 Ib N was applied in monthly lots in 1960–1; in some instances yield was significantly reduced by increased N application, apparently as a result of increased frost susceptibility. It is concluded that an application of about 174 lb N/ac/annum is the maximum desirable if there is a danger of frost.
