Southwest ND (8/31/17)

Information from the Southwest region of North Dakota.

Most in the region have received rain over the past couple of weeks, but the rain levels have been very variable. Between Aug. 16th and Aug. 30th, the NDAWN stations observed 0.57 inch of rain in Dickinson, 0.11 inch of rain in Beach, 0.05 inch of rain in Bowman, 0.01 inch of rain in Hettinger, and 0.05 inch of rain in Mott. The rain earlier in the month has helped push many of the crops along, but effects from the drought are still visible across the southwest. Although there are few acres of soybeans in the region, the soybean fields I’ve seen across the region look surprisingly good. Most corn in the region is in the R5 or dent stage (below) and most sunflowers are in the late R5 to R6 stages. Within both corn and sunflower fields there is a great amount of variability in growth stages, with some late emerging crops scattered throughout the stand.

Small grain harvest is wrapping up across the region with many beginning to work on post-harvest weed control. Canada thistle, marestail, and kochia are in high numbers throughout the countryside. This fall we will be conducting the National Sunflower Association’s Sunflower Crop Survey. In the survey, we are looking for a yield estimate along with yield limiting factors such as insect damage, diseases, and weeds. If you have sunflower fields that you would like surveyed, contact your local NDSU county ANR agent.
