The influences of slope exposure and nitrogen fertilizer on 13 cool season grasses and crownvetch were evaluated on 4:1 north- and south-facing roadside backslopes in eastern Nebraska over a 3-year period. Establishment rates, seedling stands, and ground cover trends were compared. Slope exposure did not greatly influence species performance. However, Kentucky bluegrass and western wheatgrass grew best on the north-facing slope and crownvetch exhibited severe symptoms of moisture stress during the summer months on the south-facing slope but recovered with fall moisture and cooler temperatures. All grasses required annual nitrogen applications to maintain acceptable cover. Dense stands of crownvetch became established after one growing season and increased in size without maintenance.
