ISSUE 15 September 18, 2008
During the first half of September, the region received rain ranging from 1.1 inches at Linton and Robinson, to 3.7 inches at Fingal, based on NDAWN (North Dakota Agricultural Weather Network). This late growing-season moisture helped seed development in the longer-maturing or later-planted row crops, but also will help start recharging soil moisture for next year’s crops.
Scattered spring wheat and canola fields can still be found that are left to be harvested in the northern part of this region. With the exception of areas generally west of Hwy 3, small grain yield and quality have been good to excellent. Dry bean are being knifed and swathed, and some harvest has started. Flax harvest also is in progress. Soybean and sunflower are nearing or are at physiological maturity.
Corn stages generally range from early to full dent, and the crop continues to be behind in development compared to previous years. Corn planted on May 1 at Carrington was at about 1790 growing degree day (gdd) units, Linton at 2020 gdd units, and Oakes at 2140 gdd units as of September 16, with these sites at minus 110 to 170 gdd units compared to the 5-year average. As a rule-of-thumb, corn at full dent will require another 10 to 15 days to reach maturity and corn at early dent will require another 20 to 25 days to reach maturity before a killing frost. We can likely count on wet corn this fall, but if the killing frost is delayed until early October, corn generally should have high yield and acceptable test weight.
