South-Central/Southeast ND (08/27/20)
The region’s rainfall from May 1 to August 24 ranges from 4.7 inches (Robinson) to 15.2 inches (Oakes), with the Carrington Research Extension Center (CREC) receiving 8.2 inches (source: NDAWN). During August 1-24, rainfall ranges from 0.4 inch (Courtenay) to 3.6 inches (Tappen), with the CREC receiving 0.8 inch.
Corn growth stages range from milk to dent (R3-5) and soybean range from seed development to initial maturity (R5-7). Timely planted dry bean varieties are nearing or are at physiological maturity (R8-9 stages). Most sunflower fields have dried ray flowers (R6 stage) up to the back of heads yellowing (R7-8 stages).
The CREC’s 2020 dryland spring wheat variety trial data are available at the website. The 2020 trial contained 56 named varieties averaging 42.3 bu/acre with 17.4% protein. Nine of the 29 varieties tested in the CREC dryland trial during the past three years with yield averaging greater than 55 bu/acre (range of 56.2-60.3 bu/acre): CP3530, Faller, Lang-MN, LCS Trigger, ND Frohberg, Prosper, Shelley, SY Valda and TCG-Spitfire.
Remember to be surveying fields and field edges for Palmer amaranth (and waterhemp) as canopies open with plant maturity in small grain, soybean, dry bean and other short-statured crops.
