8364. Schirman, R. and C.L. Canode. 1979. Direct seeding of annual field crops into bluegrass sod.. WSU Agr. Expt. Sta. Bull. XB 876, Pullman, WA.
Glyphosate (Roundup) was applied at rates of 1-1.5 lb/ac killed 85-90% of an established bluegrass stand and allowed direct seeding of winter wheat, spring wheat, peas, or lentils without any tillage. Burning of bluegrass residue increased vigor and yield of wheat but had inconsistent effects on legume yields. Success in killing the sod was dependent on active growth, which is influenced by weather and the varieties used. These factors should dictate the herbicide application date.

10020. Koscelny, J.A., T.F. Peeper, J.B. Solie, and S.G. Solomon. 1990. Effect of wheat (Triticum aestivum) row spacing, seeding rate, and cultivar on yield loss from cheat (Bromus secalinus).. Weed Technology 4:487-492.
Field experiments were conducted in Oklahoma to detemine the effects of row spacing, cultivar, seeding rate and water or ammonium fertilizer injection in the row at seeding, on the competitiveness of hard red winter wheat with cheatgrass. All treatments were planted with either weed-free wheat or cheat-infested wheat seed. Decreasing row spacing from 23 to 8 cm increased yield of weed-free wheat at two of three locations and cheat-infested wheat in six of ten experiments. Increasing seeding rate from 265 to 530 seeds/m increased wheat yield. Injecting water at 20 ml/m of row at seeding did not increase wheat emergence or yield. Cheat seed production was not consistently suppressed by any one cultivar.
