Abstract
Sod-seeding alfalfa into swards of smooth and meadow bromegrass, tail and intermediate wheatgrass, and orchardgrass and mixtures of these grasses with alfalfa using glyphosate or paraquat to suppress the existing vegetation was evabrated. Glyphosate (1.7 kg/ha) or paraquat (0.6 kg/ha) was applied 12 days prior to sod-seeding alfalfa (645 PLS/mz). Glyphosate completely suppressed or killed ail the grasses and as a result, excellent stands of aifaifa were obtained producing 5.8 to 6.4 Mg/ha the establishment year at Mead, Neb., without irrigation. The grass-alfalfa mixtures were also converted into pure stands of alfalfa by using glyphosate. Glyphosate suppressed but did not kill the existing alfalfa. Sodseeding in pure stands of grasses following paraquat application produced stands that were approximately 50% grass and 50% alfalfa. Paraquat bad a limited suppressive effect on alfalfa and sod-seeded alfalfa did not become established in plots containing old alfalfa.
