SEEDING RATE AND PLANTING DATE. A SPECIAL STUDY OF SELECTION, ESTABLISHMENT AND MAINTENANCE OF VEGETATION FOR EROSION CONTROL OF ROADSIDE AREAS IN GEORGIA

Sericea, Interstate and Virgata lespedezas, Brunswickgrass, Wilmington and Pensacola bahiagrasses were seeded at 20, 30, 40 and 50 lb/A rates in April, May and June on eroded Cecil soil at the Plant Sciences Farm of the University of Georgia near Bogart, Georgia. Observations for plant stand were made 1, 2, 3, and 4 months after planting. All species produced satisfactory cover of sufficient density to prevent erosion when seeded in April or May. Only Brunswickgrass and Virgata lespedeza produced adequate cover from June planting. The 30 lb/A seeding rate was adequate for all species but 40 and 50 lb/A rates slightly increased plant numbers and cover percentage. Higher seeding rates cannot compensate for out-of-season planting of these species.
