Southwest ND (09/10/15)

Information from the Southwest region of North Dakota

A majority of small grains have been harvested with a few spring wheat fields still standing. Fall burndown should be done soon before winter wheat to control the green bridge and remove the host plants for the wheat curl mite, vector of wheat streak mosaic virus.

This year NDAWN recorded 9.14 inches of rain in Dickinson from May 1st to September 9th. In May 1.73 inches were recorded with 3.67 in June, 2.26 in July, and 0.95 in August. The only rainfall recorded in Dickinson so far in September was on September 5th with 0.52 inches.

Corn should be chopped soon for silage as moisture decreases. According to J.W. Schroeder’s “Corn Silage Management” NDSU extension publication, “the highest energy values were at the 2/3 milk line. This is due to reduced digestibility of the stover portion of the plant with advancing maturity. As a rule of thumb, corn silage quality will be optimum if the grain fill is allowed to occur until the milk line is one-half to two-thirds of the way down the kernel. Harvesting at this stage usually results in near optimum moisture content for storage of the corn silage.” Read more in the Corn Silage Management extension publication (
