South-Central ND

During August 13-19, NDAWN sites receiving 0.5 to 0.75 inches of rain included Harvey, McHenry and McLeod while other areas in south-central ND received 0.3 of an inch or less. The regionís estimated daily crop water use on August 19 for corn (May 15 emergence), soybean and dry bean (May 29 emergence), and sunflower (June 5 emergence) was 0.15 to 0.24 inches. Dry and warm weather would be welcome for small grain, canola, and hay harvest, but additional rainfall is needed to maintain yield potential of our late-season crops. Scattered frost damage to corn was reported during the past week in Emmons and McIntosh counties. High winds have caused lower stem breakage of isolated dry bean plants, primarily in fields with low or non-uniform plant densities. Winds have also scattered canola, mustard, and flax swathes in some fields in northern counties.

Small grain harvest is near completion south of I94 and in progress north of I94. Preliminary reports indicate average or less seed yield due to moisture and/or heat stress. Generally, wheat protein is 14% or greater, while other quality factors appear variable. Canola has been swathed and harvest of canola and flax has begun. Seed yield of both oilseed crops is expected to be less than average. Throughout the region, corn is in the milk to denting stages, soybean are in the R5-R6 stages (seed formation), dry bean are fully podded and leaves are starting to yellow, and sunflower are near the end of bloom or past. Corn harvest for silage will begin in late August in southern counties.

Insecticide application for the red seed weevil in sunflower has been a common task in the region. Growers should continue monitoring and treating (if needed) late-season crops for grasshoppers. Preharvest herbicide application or swathing of wheat and flax has been a common practice due to late-season weed growth.
