The Cutting Edge Podcast Episode 25: Day in the Life Hazelnuts

Join hazelnut researcher Jason Fischbach as he traverses the state of Wisconsin to visit hazelnut research trials, farms, and processing facilities. Heading south from Ashland , his first stop is the Kickapoo Culinary Center in Gays Mills where Pete Lammers describes hazelnut feeding trials in cooperation with Iowa State University. Then Paul Ronsheim, grower and […]

Interseeding Cover Crops

Corn and soybean growers interested in using cover crops following corn and soybean crops may look to interseeding to establish a cover crop earlier in the season.

Aphanomyces Root Rot of Alfalfa

Aphanomyces root rot (ARR) is a serious disease of both recently seeded alfalfa and established alfalfa stands.  ARR can cause severe yield reductions in affected alfalfa fields.  Variations of the disease also occur on many other legumes (including soybean, snap bean, faba bean, red kidney bean, pea, red clover, and white clover) and can cause significant losses in these crops as well.

Considerations for Selecting Annual Grain Hybrids and Varieties

The selection of corn hybrids and soybean and small grain varieties has a major influence on yield and overall profitability of crop production.  The disparity in yield between varieties on both ends of the spectrum is quite large.  At the University of Wisconsin, corn hybrid research has shown an average yield spread of 70 bushels/acre […]

Harvest Season Clean Out

Limiting the spread of weed seed between fields is a key part of an integrated pest management system. This is especially important, because the weeds present at harvest were allowed to produce seed and have survived other control attempts during the growing season. These weed seeds, if allowed to spread and germinate, have the potential to become difficult to control elsewhere.

Effect of Seedling Year Stress on Future Alfalfa Yields

Stress in the seeding year reduces future yields of alfalfa. This occurs because the seeding year determines the stand plant density as well as individual plant size and vigor. The following paragraphs will show that autotoxicity, potato leaf hopper, cover crop, and, possibly, drought stresses in the seeding year will reduce alfalfa yield in future years, even when the stress is gone.
