South-Central/Southeast ND (05/06/21)

Information from the South Central/Southeast region of North Dakota.

Crop planting is rapidly progressing but plant establishment continues to be slow due to cool air and soil temperatures, and generally dry soils. According to NDAWN, rainfall April 1 through May 3 ranged from 0.2 inch (McHenry) to 1.7 inches (Lisbon) with numerous sites under 0.5 inch and 0.6 inch at the Carrington Research Extension Center (CREC).

Alfalfa regrowth at the CREC is at <4-inch height. Winter rye and winter wheat are in the seedling to tillering growth stages. Small grain planting in the region should soon be complete. Early April planted small grain have emerged during the past week and are at 1-leaf (see picture). Estimates on planting progress as percent of acres for corn ranges from 30-50% and soybean at 20-30%.

Using data from a multi-year CREC corn study, the plant population (with hybrids of 83- to 85-day relative maturity) that gives maximum economic return based on seed costs of $200-225/unit (80,000 seeds) and market price of $5/bu is 33,500 to 34,000 plants/A.
