With processors on the eve of offering protein and oil premiums, growers know those criteria are gaining importance as they pick their soybean varieties.
But what do the percentages really mean? Do they really tell a grower what the protein or oil content will be with a certain variety when grown on the farm?
It depends on the company - where the protein and oil contents were taken, by what method and how they were determined, says Charles Hurburgh, Iowa State University ag engineer.
"Everybody isn't on the same basis," explains Hurburgh.
"The best way to express protein and oil is not in absolute numbers, but against a benchmark. Compare the average at the location the data was collected. Then, instead of saying protein is 36% and oil is 18%, you can say the protein of this variety should be one percentage point above average and the oil should be about equal," he adds.
The following list of new soybean varieties comes from breeders and agronomists at USDA-ARS, universities and private companies. All protein and oil percentages are compared on a 13% moisture basis . (Note: some were measured in different ways.)
In selecting varieties, Hurburgh recommends that growers quiz seed companies about how protein and oil data were determined before banking on premiums. Growers can also compare percentages against the annual state and regional survey provided by the American Soybean Association and United Soybean Board (see printed article).
Keep in mind that only up to four varieties per company are listed here. And that much of the yield data reported is based on company trials. So browse through this wish list and then talk with seed company representatives about what else may be available.
