Predicting When Soybeans Will Emerge

By WCM Staff on 4/29/2009 12:00 PM

Ten years ago, very few people outside of academia were concerned about the number of growing degree units (GDU) required for soybean emergence. Today however, things are dramatically different.

Spring Removal of No-till Alfalfa in Wisconsin

By WCM Staff on 4/29/2009 11:23 AM

Many of the same herbicides used in the fall are also effective in the spring and are listed in table 1 along with rate ranges and plant-back restrictions for field corn.

A new publication from Shawn Conley and John Gaska titled, Factors to Consider When Lowering Soybean Seeding Rates in 2009, can be found at this link. http://soybean.uwex.edu/documents/Factors_to_Consider.pdf

Wheat Stand Assessment

By WCM Staff on 4/16/2009 11:34 AM

Most winterkill that growers experienced in 2008 was related to prolonged ice sheets that limited plant respiration and ultimately lead to plant death. In 2009, Wisconsin wheat growers are again dealing with winterkill; however the culprit this year appears to be death by exposure (lack of snow cover).

Corn plant density

By WCM Staff on 4/9/2009 12:09 PM

The plant density that maximizes corn grain and silage yield has been increasing through time. The economic optimum plant density is a function of corn yield and quality responses, seed cost, and grain or silage price. The economic plant density is lower than the plant density that maximizes yield.

Application techniques Fact Sheet for boom sprayers

By WCM Staff on 4/9/2009 11:36 AM

Download a new fact sheet which covers spraying situations that every applicator, private or commercial, will face: making the opening rounds, spraying into corners, the importance of pattern and swath overlap, spraying around waterways, and spraying irregular shaped fields.

WSMB Offers Free Soybean Cyst Nematode Testing

By WCM Staff on 4/9/2009 10:15 AM

This program is intended for growers to sample several of their fields in order to identify if SCN is present and at what levels. Growers will be responsible for collecting soil from fields suspected to have SCN and then sending the sample to the SCN testing laboratory for analysis.

Winter Wheat Workshops 2009

There are three winter wheat workshops that will be offered in early March 2009 at Janesville, Fond du Lac, and Waldo, WI.

Why Bin-Run Soybeans Don’t Pay

By WCM Staff on 1/29/2009 2:56 PM

Dramatic increases in soybean seed costs for 2009 (25 to 109%) have many growers rethinking their soybean seed options. The most drastic alternative being floated in the coffee shops is brown bagging or planting “saved” soybean seed. Before a grower considers this option we must revisit the legal issues and agronomic considerations associated with this practice.

Sainfoin Not Recommended for Wisconsin

By WCM Staff on 1/29/2009 2:03 PM

Sainfoin (Onobrychis vicifolia) -- New varieties of sainfoin have been released in Montana with improved yield, however these varieties have not been tested in Wisconsin. The lack of yield in the seeding year, adaption to high pH, low tolerance of wet soils, and, susceptibility to crown rot causing short stand life indicate that this species is not likely to be useful in Wisconsin.
