South-Central/Southeast ND (08/05/21)
ccording to NDAWN, the region’s July rainfall total ranges from 0.1 inch (Carrington, Courtenay and Dazey) to 2.6 inches (McHenry). Estimated daily water use during the past week (July 27-Aug 2) for plants emerged May 20 was about 0.25 inch per day for corn and soybean.
Harvest is in progress for the region’s small grain crop. Grain yield is highly variable and well below average, but quality is good (e.g. high test weight and protein).
The following are the most advanced row crop growth stages observed at the CREC earlier this week: corn, R2 (blister) but nearing R3 (milk); soybean, R5 (seed development on pods within the upper four plant nodes); dry bean, R6 (seed developed to at least 0.25 inch in length); and sunflower, R6 (drying ray flowers). At these stages and normal growing conditions, approximate days to physiological maturity: corn, 40-50; soybean, 40-45; dry bean, 35-40; and sunflower, 30. However, with continued adverse growing conditions, these periods likely are liberal as plants attempt to produce seed as quickly as possible.
Upcoming crop tours:
August 12 – CREC Fingal area off-station corn research; 8 a.m.
August 25 – CREC Row Crop (corn, soybean and dry bean); 12:45 p.m.
