South-Central/Southeast ND (08/12/21)
According to NDAWN, the region’s April 1 to August 9 rainfall ranges from 3.4 inches (Dazey) to 11.2 inches (Jamestown). During July 1 to August 9, total rainfall less than 0.5 inch (0.08 to 0.37 inch) occurred at Carrington, Cooperstown, Courtenay, Dazey, Fingal and Robinson. Estimated daily water use during the past week (Aug 3-9) for corn and soybean plants that emerged May 20 was slightly above 0.2 inch per day.
Small grain harvest for the region is at least at the halfway mark. Preliminary reports on spring wheat grain yield ranges from zero (harvested as forage) to 70 bushels. Fields exist that have higher seed protein than yield! The Carrington REC’s dryland HRS wheat variety trial averaged 56.4 bu/A, 62.3 lb/bu and 15.9% protein (data available at www.ag.ndsu.edu/varietytrials/carrington-rec/2021).
The following are the most advanced row crop growth stages observed at the CREC earlier this week: corn, R3 (milk) but nearing R4 (dough); soybean, R6 (full seed development in pods within the upper four plant nodes); dry bean, R7 (oldest pods with fully developed seeds; ‘striping’ of pinto bean); and sunflower, R7 (loss of green color from back of head). Generally, dry bean and sunflower are better tolerating the adverse environment versus corn and soybean. A common decision being determined is whether corn and soybean will be harvested as grain or forage.
Row Crop Tour – Wednesday, Aug.25
Farmers, crop advisers and agricultural industry representatives are invited to view field research trials and receive production recommendations on corn, soybean and dry edible bean during the annual Carrington REC’s row crop tour on Wednesday, Aug. 25. This field tour follows the NDSU Extension virtual soil health meeting broadcast at the Carrington REC during the morning starting at 9:30 a.m. (preregister at: ndsu.edu/soilhealth).
Registration for the row crop tour begins at 12:30 p.m. with a sponsored meal served at 12:45. The program begins at 1:30 and includes the following topics:
*Using web-based mapping to enhance management of crop fields
*Crop cultivar selection using the new NDSU website
*Dry bean variety performance
*Research update on cover crops (with emphasis on winter rye) for soybean and dry bean
*Impact of row spacing and seeding rate, and fungicide application timing on white mold (sclerotinia) management in dry bean
*Corn starter and foliar fertilizer research update
