Abstract
  • Treasure spring wheat was grown on sloping ground with and without mechanically applied furrow mulching. Furrow mulching used 800 lb/ac of wheat straw. Mulched and non-mulched furrows were irrigated five times during the season receiving 483 and 19.0 and 40.9 ac-in of irrigation water, respectively. For non-mulched furrows, infiltration totaled 13.0 ac-in, while runoff constituted 27.9 ac-in or 68.1 percent of applied water. For mulched furrows, infiltration totaled 13.2 ac-in, while runoff constituted 5.8 ac-in or 30.5 percent. Average sediment yield was reduced from 49.4 tons/ac to 2.2 tons/ac with furrow mulching. Grain yield increased by 15.7 bu/ac with furrow mulching, from 96.0 to 111.7 bu/ac.
