Abstract/Contents:Presents a study conducted at the University of Arizona during the late 1960s to evaluate ammonium nitrate, ammonium sulfate, urea, and sulfure-coated urea as annual fertilizers for annual ryegrass. Details methods and materials used during the experiment, noting that "the four fertilizers were each applied at rates of one and two pounds of nitrogen per 1000 ft2 [square feet]." Reports that "there were no significant differences among the effects of the four fertilizers applied...on [the] color production of annual ryegrass except on the April 11 evaluation date." Provides a table listing nitrogen sources and rates applied on several dates. Concludes that "[the] color production of ryegrass may be enhanced more by ammonium sulfate than the other fertilizers, especially when a low application rate is used."
