ISSUE 3 May 28, 2009
During May 20-26, according to NDAWN data, Harvey received 1.5 inches of rain while Edgeley, Lisbon, Marion, and Oakes received less than 0.1 inch. The following are accumulated corn growing degree day (gdd) units during the period of May 4-26 (deficiency compared to long-term average): Carrington = 144 (-94), Jamestown = 166 (-57), and Oakes = 205 (-28). The region averaged 10-11 gdd units/day during this period. With delayed planting and below normal heat units, our corn is off to a slow start. Crop planting progress continues to be widely variable among fields and farms but south of Interstate 94, seeded small grain acreage is greater than 90 percent and corn is about 75 percent planted. Small grain and corn planting likely will be completed throughout the region by June 1. Planted soybean, dry bean, and sunflower acres are at 10-30 percent. A significant amount of cropland will not be planted due to high soil moisture. Small grain fields seeded during the first week in May are in the two-leaf stage and corn has emerged. Weed growth rate and density is increasing with recent rain and warmer temperatures.
