Effect of Frost Damage on Immature Corn (09/24/20)

When freezing temperatures arrived in the state earlier this month most of the corn was not mature. Important questions arising from this event include: What kind of yield loss resulted from this early end of season? Will the crop’s test weight be low? Will frost damaged immature corn dry-down more slowly than mature corn? As with most agronomic questions, the answers to these questions are, it depends!

NDSU 2020 Soybean IDC Test Scores Available (08/27/20)

Soybean varieties differ in their tolerance to iron-deficiency chlorosis (IDC). Selecting a soybean variety with tolerance to IDC is the most important management decision producers can make in avoiding or reducing the negative yield effect of chlorosis.

Planting Winter Wheat on Prevent Plant Acres (08/13/20)

Winter wheat was planted on only 40,000 acres this past year, the smallest area since 1995, and only a fraction of the 870,000 acres planted in 2014.

Interseeding Camelina and Rye into Soybean at R6 (08/13/20)

Interseeding cover crops into soybean is not a common practice in North Dakota due to limited soil water, a short growing season, and the need for adapted winter hardy species to produce a good established stand of a cover crop.

Sixty-Inch Row Spacing in Corn (08/06/20)

There is interest in growing corn with a 60-inch row spacing to facilitate the establishment of cover crops during the growing season. Establishing cover crops in corn with the commonly used row spacings of 22- or 30-inch row spacing can be very challenging.

Managing Excess Water Utilizing Tile Drainage (08/06/20)

The 2020 cropping season has been challenging. In some parts of North Dakota, there has been drought and in other pockets of the State there has been abundant rainfall, causing excess water conditions (Photo 1).
