South Central/East ND (08/17/17)

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

The region’s NDAWN stations indicate August 1-15 rainfall ranging from 5.8 inches (Brampton) to 1.8 inches (McHenry). Total rainfall from April 1 to August 15 ranges from 12.8 inches (Cooperstown) to 6.7 inches (Harvey). Estimated daily water use by corn and soybean during the past week (August 9-15) averaged 0.1 inch/day. The August rainfall is valuable for supporting growth of row crops but is hindering small grain harvest and reducing seed quality.

Winter cereal, barley and field pea harvest is essentially complete. Field pea yield is ranging from 30-50 bu/acre with good quality. Barley yield is highly variable (ranging from hayed instead of harvested to 100+ bu/acre) and seed quality average or less. Spring wheat harvest is in progress, with preliminary yield reports highly variable (15 to mid 70 bu/acre) and good protein levels.

Corn planted during the first week in May or earlier generally is in the milk to dough (R3-4) stages. Based on NDAWN growing degree day units accumulated from May 1 planting date to August 15, the region is on par to slightly behind the long-term average. Soybean generally are in the seed formation stages (R5-6); dry bean in the late seed formation (R7) stage; and sunflower in late bloom (R5) to ray flower wilted (R6) stages.

Row Crop tour

Farmers, crop advisers and ag industry representatives are invited to view field research trials and receive production recommendations on corn, soybean and dry edible bean during the NDSU Carrington Research Extension Center Row Crop tour on Thursday, August 24 (registration at 4 p.m. and tour at 4:30 p.m.)


Tour topics, presented by NDSU Extension Service crop specialists and Experiment Station scientists, include:

* Corn development update and starter fertilizer research summary

* Soybean variety selection and production update

* Choosing row spacing and planting rate to minimize impact of white mold in soybean

* Dicamba injury in soybean

* Cover crop strategies for soybean and dry bean

* Dry bean variety performance and NDSU breeding program

* Dry bean plant establishment and nutrition

* Optimizing fungicide control of white mold in dry bean


Three and a half continuing education credits will be available for certified crop advisers (CCAs). A supper sponsored by associated North Dakota commodity organizations will follow the tour. Additional information about the tour is available at 701-652-2951 or
