The protein content of the grasses mowed frequently averaged much higher than when the grasses were cut only at the end of the growing season. This held true on both fertilized and unfertilized areas. The protein content of pasture grass in a grazed condition can be increased and maintained at a somewhat higher level than ordinary by frequent light applications of a nitrogen fertilizer. The pasture grasses used in this experiment gave much higher forage yields from the nitrogen applications as shown by yield records obtained and as indicated from results obtained in the pasture experiment. Rainfall (rather than available soil nitrogen) is a limiting factor in forage production, as the ratio between the total nitrogen content of the grass and the pounds of forage produced is flexible.
