Effects of Compaction, Depth of Planting, and Soil Moisture Tension on Seedling Emergence of Alfalfa1

  1. Glover B. Triplett and
  2. Milo B. Tesar2



With no irrigation following seeding, moisture conditions near the seed and initial emergence of alfalfa seedlings were improved progressively by increasing planting depths from 0 to 1 inch and soll compaction from 0 to 12 psi. When 1/2 inch of irrigation was applied after seeding, maximum average emergence was obtained from the 1,/2-inch planting depth with a soil compaction of either 6 or 12 psi. Compaction was less beneficlal to emergence as planting depth increased beyond 1/4 inch, especially when irrigation followed planting.
