Bean Pod Mottle Virus – A No-Show in Wisconsin Soybeans in 2004
Wisconsin Crop Manager Insects and Mites By WCM Staff on 1/17/2005 5:28 PM
The late season 2004 BPMV analyses are complete and the season ended as it began, with minimal detection of BPMV in bean leaf beetles collected in spring alfalfa fields followed by no positive detections of BPMV in late season soybean plants throughout the state.

Negotiating the Value of Immature Corn Silage
Wisconsin Crop Manager Crops By WCM Staff on 9/8/2004 9:00 PM
Arriving at a fair and equitable price for corn silage is difficult due to the number of factors involved that are dynamic and biologically variable. Some factors include production costs, grain price, harvesting costs, costs of handling, hauling and storage, grain drying costs, fertility value of stover, and forage quality (especially starch content and neutral detergent fiber digestibility-NDFD).

Grazing Soybeans
Wisconsin Crop Manager Crops By WCM Staff on 8/25/2004 7:00 PM
Although there isn't much data on grazing soybeans, beans can be high in quality and provide good grazing. Recommendations are listed.

Rehydration of Corn Forage Standing in the Field
Wisconsin Crop Manager Crops By WCM Staff on 1/14/2004 11:00 PM
Many fields in Wisconsin had uneven crop development during the 2003 growing season. We were interested in the forage moisture differences of corn in knoll and swale areas of the field.

Fall and Spring Forage Yield and Quality from Fall-Seeded Cereal Crops
Wisconsin Crop Manager Crops By WCM Staff on 9/3/2003 7:00 PM
Cereal crops such as oats, barley, triticale, wheat, and rye may be a source of emergency fall forage and/or a source of forage the following spring. The choice of which specie to plant depends on the importance or need for forage in the fall as opposed to forage in the spring.

Planting Corn For Silage Following Winter-Killed Alfalfa
Wisconsin Crop Manager Crops By WCM Staff on 4/23/2003 9:00 PM
The following is a summary of planting date trials conducted at Arlington, WI. The objective of these trials is to measure the impact of planting date on corn forage yield and quality.

Follow-up On Harvesting Corn Silage From Highly Erodible Land
Wisconsin Crop Manager Crops By WCM Staff on 6/12/2002 10:00 PM
In the 25 April 2002 issue of the Wisconsin Crop Manager, I suggested one way to make T requirements is to raise the cutter bar on the corn silage chopper. This strategy lowers silage yield, but a trade-off exists whereby silage quality is increased.

Managing Corn Silage on Highly Erodible Land
Wisconsin Crop Manager Crops By WCM Staff on 4/24/2002 7:00 PM
By correlating studies that estimate percent ground cover from corn residue mass with cutting height studies conducted in Wisconsin we might be able to derive some general guidelines for managing corn silage on highly erodible land.

Uneven Maturity at Corn Harvest – Handling Silage and Grain
Wisconsin Crop Manager Crops By WCM Staff on 9/5/2001 10:00 PM
The corn production season of 2001 has been extremely "variable." This year’s variability is more within fields than between fields and the harvest season will present some special handling problems.

Alfalfa Management Under Moisture Stress
Wisconsin Crop Manager Crops By WCM Staff on 7/18/2001 10:00 PM
Moisture swings during growing season 2001 have been significant to say the least. Although the current round of dry weather may not rival the memorable droughts of prior years, it is raising management concerns.

Milk2000: A New Way to Estimate Corn Hybrid Silage Performance
Wisconsin Crop Manager Crops By WCM Staff on 12/13/2000 11:00 PM
Because the cows maintenance energy requirements were partitioned against the total diet in MILK2000 rather than against only corn silage as was done in MILK95, there was a base increase in our new estimate of milk per ton which was of equal value across all samples that did not influence ranking of hybrids.

Predicting Corn Silage Harvest Dates
Wisconsin Crop Manager Crops By WCM Staff on 8/23/2000 6:00 PM
One of the more difficult managment decisions when producing corn silage is properly timing harvest. Corn silage that is too wet will yield less, result in silo seepage and produce a sour tasting silage resulting in lower intake by livestock. If corn silage is too dry then yield is often reduced, heat damage and mold more easily develops in the silo because fermentation is inadequate, and the silage has lower protein, digestibility and the vitamins A and E.

Calculating Grain and Silage Yields for Loan Deficiency Payments
Wisconsin Crop Manager Crops By WCM Staff on 10/13/1999 10:00 PM
Much progress has been made in breeding adapted high yielding hybrids that are more resistant to biotic and abiotic stresses. Does the old relationship between grain and silage yield still hold?

How Late Should Corn Be Planted For Silage Production?
Wisconsin Crop Manager Crops By WCM Staff on 5/27/1999 1:01 PM
The optimum date for planting corn for grain is between May 1 and May 7 in Wisconsin. In many years, farmers are still wanting to plant corn after June 1. Later planting dates mean lower grain yields and higher grain moistures. At some date the best use of corn becomes either as high moisture corn or corn silage.

What Can We Learn From the Corn Forage Drydown During 1998?
Wisconsin Crop Manager Crops By WCM Staff on 3/2/1999 11:00 PM
Before 1998 becomes too foggy in our memory, what lessons can we learn from the corn forage drydown during September 1998?

Corn Silage Response to Planting Date
Wisconsin Crop Manager Crops By WCM Staff on 6/17/1998 9:00 PM
The standard recommendation for late planting corn grown for grain is that it should not be planted after June 5 in northern WI and June 10 in southern WI. But how late should we plant corn intended for silage use?
