Soybean Cultivar Maturity Rating and Yield (05/26/16)

About 81 percent of the 2016 soybean crop has been seeded as of Sunday May 22. As we are nearing the end of the planting season, producers sometimes wonder about which relative maturity (RM) will provide the best results.

Frost Damage in Alfalfa: What to do After it? (05/19/16)

Last weekend, air temperature descended to 23◦F for as long as 5 hours in some locations in North Dakota (see NDAWN map from 2:00 to 4:00 AM, 14 May 2016). Alfalfa in areas in dark blue color were exposed to temperatures below 25◦F for at least three hours.

2015 Sunflower Survey Results (05/19/16)

During the 2015 sunflower growing season, 14 trained teams - including agronomists, entomologists, pathologists, crop consultants and/or producers - randomly stopped at 106 sunflower production fields in ND. Each team evaluated plant density, yield potential, disease, insect, and weed issues for each field.

Impact of Planting Dates on Dry Edible Bean (05/12/16)

Six planting date trials were conducted by NDSU during 2012-15 to explore if dry edible bean seed yield and quality can be increased with early planting compared to the normal planting period (last 10 days of May through first 10 days of June).
