Spring Seed Guide Issued - UNL CropWatch, Jan. 3, 2012

January 3, 2012

Results from this year’s UNL field trials are available in the Extension Spring Seed Guide, EC 101. This guide can help producers gauge achievable yields with hybrids currently on the market based on unbiased field trials. It includes information on corn, soybean, sorghum, alfalfa, and sunflower trials and a list by the Nebraska Crop Improvement Association of certified seed sources and private industries developing and marketing hybrids and varieties in Nebraska.

Copies are available at local county offices or can be viewed online in the CropWatch Variety Test  section. (To access reports for specific crops online, use the list in the left navigation bar.)

Tables 1 and 2 (below) provide a brief summary of results from the corn and soybean trials at each location. For more detailed information on the performance of specific brands and hybrids, see the Spring Seed Guide (EC101).

The results include hybrids submitted by commercial companies as well as those entered by producers. Commercial product names are not included unless the field trial entry was made by the company. If you would like to see additional hybrids included, encourage companies to participate in these trials.

If your hybrids don’t yield as much as those listed in the results, it may be time to seriously look at other brands.
