South-Central/Southeast ND (05/21/20)

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

With warm air and soil temperatures and absence of rain, crop planting and development of emerged plants have accelerated. According to NDAWN, average daily bare soil temperatures are in the mid-50s to low 60s. Rainfall during May 1-18 ranged from 0.25 inch (Robinson) to 1.9 inches (Dazey and McHenry), with the Carrington REC receiving 1.1 inch.

Alfalfa regrowth is at <8-inch height. Winter rye and winter wheat are in the late tillering to early flag-leaf emergence stages, depending on last fall’s seeding date. Seeding progress with small grain and corn in the region continues to be variable, possibly nearing 50% of acres completed. Barley and spring wheat seeded late April are at the 2- to 3-leaf stages. Based on growing degree day units, corn planted on or before April 25 should be emerged.

Soybean planting continues and dry bean planting also is starting. Results from a recently evaluated database of NDSU soybean planting rate and row spacing field trials in eastern North Dakota indicate maximum yield was reached at 170,000 pure live seeds (PLS)/acre in narrow rows (12-14 inches). If planting in wide rows (24-30 inches), yield was greatest at 190,000 PLS/acre. These numbers can be used as a guide, but farmers should fine-tune their planting rates based on soybean seed and market prices, soil productivity, etc.

Foxtail has joined the list of emerged weeds.
