South Central ND (05/19/16)

Information from the South Central region of North Dakota.

The region’s NDAWN stationats.endres.corn.frosts indicate rainfall of 0.2 to 0.4 inches only in southern counties during the past week (May 11-17). Rain is welcome throughout the region. The NDAWN station with lowest air temperature was 21 degrees F at Pillsbury on May 14 while other sites that day had low temperatures ranging from 23 to 30 degrees. Frost damage to crops appear to be limited to superficial leaf damage, e.g. corn (see picture).

Barley and spring wheat seeded the first-half April are at the 3-leaf stage (tillering). Corn planted on April 30 has accumulated 125 to 180 growing degree day (GDD) units through May 17. April-planted corn is in the one- to two-leaf (V1-2) stages. Planting of soybean acres should be nearly completed by the end of this week. Planting of dry bean and sunflower is beginning. See the following website for a NDSU research summary on early versus normal dry bean planting dates:

Pre-emergence herbicide application for planted row crops continues, though challenged by environmental conditions. Also, post-emergence herbicide application in small grain is in progress.
