THE EFFECT OF THE RATE AND TIMING OF NITROGEN APPLICATIONS ON THE SEED YIELD AND COMPONENTS OF YIELD IN S48 TIMOTHY (PHLEUM PRATENSE L.)

An experiment on the effect of the rate and timing of N applications on the seed yield of S48 timothy is described. Some benefits were obtained from the use of nitrogen, but the results were variable, probably because of the effect of the fertilizer on root size interacting with the currently prevailing climatic conditions. It is suggested that the adverse effect of dry weather during ear initiation and development might be alleviated by the use of irrigation.
