The Response of Crested Wheatgrass and Volunteer Sweetclover to Nitrogen and Phosphorus under Dryland Conditions¹

Effect of Manure, Nitrogen, Phosphorus, and Climatic Factors on the Production and Quality of Bromegrass‐Crested Wheatgrass Hay1

“…I NVESTIGATIONS of the effect of fertilizers on tame and native grasses under semi-arid conditions have shown that both yield and quality of forage may be improved by the use of nitrogen and phosphorus fertilizers ( 2,3,4,5). As the magnitude of fertilizer response under semi-arid conditions is closely related to the weather, the economic feasibility of using fertilizers on range lands is questionable and cannot be justified at the present time.…”

The Influence of Ammonium Nitrate on the Growth and Yield of Crested Wheatgrass on the Oregon High Desert1

“…Nitrogen fertilization increased the yield of crested wheatgrass in Wyoming, Montana, and South Dakota ( 2,9,10). At Nephi, Utah ( 3), which has a precipitation pattern similar to that at Squaw Butte, creSted wheatgrass response to nitrogen was primarily greater vegetative growth early in the season.…”
