Interseeding Sideoats Grama on the Texas High Plains

Abstract

Sideoats grama was interseeded in grass stands representing intermediate stages of succession near Amarillo, Texas. Seedings at 0.5-inch depth were more successful than at one-inch. Addition of 30 lb/acre nitrogen fertilizer or legume (alfalfa) to the seeding did not increase the seedling establishment. Better grass stands with less competition from non-seeded species was obtained from seeding in late May than in March, April, or June. Highest total survival of grass seedlings was also from the May seedings.
