Description
Responses of two perennial grasses, bluebunch wheatgrass (Agropyron inerme) and big bluegrass (Poa ampla), to competition were studied in a reseeded, disturbed area. Nitrogen (N) and phosphorus (P) were added to topsoil depths of 30 and 90 cm. The objective was to determine effects of competition, between the two grasses, on forage production. Amount of forage produced was also evaluated with respect to fertilizer and depth of topsoil in combination with competition. The two species were studied as pairs of individual plants. Each pair was either a monoculture or biculture. Three stages of phenology for species represented dates for sampling on all combinations of treatments. Biomass of herbage, crown and roots was measured. Fertilizer alone did not increase forage production of either species. A significant forage increase did occur when fertilizer was added to the deeper soil. Both grasses produced more forage in biculture and when fertilized.
