Seeding Sorghum × Sudangrass Hybrids into Tall Fescue Sod1

Abstract

AbstractSorghum × sudangrass hybrids (Sorghum bicolor L. Moench × Sorghum sudanense P. Stapf.) were seeded into tall fescue (Festuca arundinacea Schreb.) sod, which had been temporarily suppressed with paraquat4 (l,l'‐dimethyl‐4,4'‐bipyridinium dichloride). Sod‐seeded De‐Kalb ‘Sudax SX‐12’, with N fertilizer banded under the seed, produced as much forage as conventionally seeded Sudax. Sod‐seeded ‘Sudax SX‐11’ and SX‐12, with N broadcast at seeding, produced less forage than conventionally seeded Sudax, unless enough paraquat was applied to damage tall fescue permanently. Combined yield of tall fescue and sod‐seeded Sudax, under the best management, was about 60% greater than yields of either fescue or Sudax alone.
