New Hybrid-Maize Improves Corn Yield Predictions Under Drought Stress February 27, 2017

Crop simulation models are powerful tools to guide research, education, and extension as well as to inform policy making. Such models generally perform better under non-water stress conditions and it has been a scientific challenge to simulate crop yield under severe drought stress.

Rotation Impact on Irrigated Corn and Soybean Yields in Nebraska February 23, 2017

On most Nebraska rainfed farms, soybean and corn are usually rotated. On irrigated fields, however, the rotation sequence tends to shift to more years of corn between soybean, and in some cases, corn is grown continuously, year-after-year.

Update on Bacterial Leaf Streak of Corn in Nebraska February 23, 2017

Bacterial leaf streak was first confirmed in the US in August 2016 when it was identified in Nebraska corn. It has now been confirmed in 51 Nebraska counties and found in corn fields across the Midwest. This article offers information on current status, identification, and management of the disease. Resistance is not currently available in hybrids and standard management measures of bacterial diseases will help mitigate but not eliminate damage.

Cutting Costs Without Hurting Yields? Check Fertilizer N Rates in Corn after Alfalfa February 22, 2017

With tight crop margins for the 2017 growing season, many farmers are looking for ways to cut input costs without hurting yields. One way to do this is by giving the appropriate nitrogen credit when calculating how much N to apply to corn grown after a prior alfalfa crop.
