Abstract/Contents: | "Annual bluegrass (Poa annua L.) and 'Penncross' creeping bentgrass (Agrostis palustris Huds.) were grown in monostand and polystand in silica sand and supplied with solutions in which 0%, 25%, 50%, 75% or 100% of the N was NH₄⁺ and the remainder was NO₃⁻. In polystand, annual bluegrass was more competitive than 'Penncross', producing more shoot and root dry weight and more tillers. Competitive ability of annual bluegrass was decreased as the percentage of NH₄⁺ increased in nutrient solution. The decrease in competitive ability was reflected by a decline in tiller number and root and shoot dry weight. 'Penncross' was less affected by N form than was annual bluegrass." |
