Nitrogen fertilizer at 30 lb./acre increased 13-year mean spring, regrowth, and fall yields of crested wheatgrass 83, 29, and 78%, respectively, above control plot yield. It increased the crude protein concentration of mature herbage, but the protein concentration decreased as fall yields increased. Mean spring plus regrowth yield, with and without N, was 82 and 85%, respectively, of the fall yield harvest on August 1. Forty-six and fifty-two percent of the fall yield with and without N, respectively, was present on May 15. Yield measurements in the 7th and 13th year revealed no yield reduction due to previous treatment on control plots but did show significant reductions in yield on plots fertilized with N and clipped in previous years on May 15. Those yield reductions were interpreted to be the result of restricted regrowth opportunity in the previous year due to weather and not to cumulative yearly clipping effects.Type
