Wheat Seeding Delay? Here’s How to Compensate August 30, 2017

Even when you plan to seed winter wheat at the optimum time, weather, equipment breakdown, or other problems may prevent it. If you're in this situation, increasing your seeding rate, using narrow row spacing, and applying other practices described here can help you achieve a successful wheat stand despite the challenges.

Estimating the Full Value of Crop Residue August 11, 2017

If you're considering cutting drought-stressed corn or sorghum for silage, you might want to take a second look at its nutrient value to the next crop if left in the field.

Corn stubble with little residue
Figure 1. After the corn was cut for silage, little plant material remained in this southwest Nebraska field to protect the soil from wind or water erosion or to capture snow moisture. The corn had been planted in a field with little wheat residue.

Should You Hay or Cut Silage from Drought-Damaged Corn Fields July 28, 2017

Drought conditions across much of Nebraska will limit grain yields in dryland corn this year, leading growers to look at other options for harvesting value from these fields. In some cases, harvesting this plant material may contribute to nutrient and water removal from the soil and may not be the best solution for your rotation or cropping system.

Post-Harvest Weed Control in Winter Wheat July 14, 2017

A strategy combining well-timed herbicide applications, split treatments, and effective cultural practices is key to managing weeds in wheat to reduce soil moisture loss and the weed seed bank. This story addresses what to consider as well as particular weed challenges in wheat.

Why Control of Volunteer Wheat is Critical to Protecting 2018 Yields July 13, 2017

Timely control of volunteer wheat and other weeds is key to managing yield loss risk in your 2018 crop. Yield-limiting risk factors affected by weed control include wheat streak mosaic and other diseases, insects (wheat stem sawfly and disease vectors), moisture loss, and increased weed seed production.

In Figure 1a the field on the right, with heavier crop residue, shows dicamba-tolerant soybeans that had been sprayed with new generation dicamba. The field on the left, non-dicamba-tolerant soybeans planted side-by-side without a buffer, shows symptoms of injury caused by dicamba, the consequences of spray drift or volatilization. Figure 1b illustrates how dicamba affects newer growth more than older leaves. (Photos by Tim Creger, Nebraska Department of Agriculture)

Dicamba Injury Symptoms on Sensitive Crops June 28, 2017

Dicamba-resistant soybean, genetically engineered to provide resistance to dicamba and glyphosate, was made commercially available for the 2017 growing season. This article looks at potential dicamba injury to sensitive crops and plants.
