Standing in Soybean Variety Trial, by Greg Roth, PSU
The results of the 2017 Soybean Performance Trials have been posted. This year’s report includes both early and late glyphosate resistant varieties at Rock Springs in Centre County and Landisville in Lancaster County. In this test, we included a description of traits to distinguish between Roundup Ready and Roundup Ready Xtend varieties. At both sites, we conducted a non-glyphosate trial that consisted of conventional, Liberty Link and STS varieties. We also included several glyphosate resistant checks in each of these tests to compare relative performance. We planted a double crop trial at our Lancaster location that included glyphosate resistant varieties. We have submitted grain samples from most entries for protein and oil analysis and those results will be posted when we get the data later this winter.
Though this year’s data is not yet available, the protein data from our 2016 Soybean Variety Trials have been posted. Average protein levels in the seven trials we conducted last year ranged from 35.1 to 36.2 and averaged 35.7%. Oil contents varied from 18.2 to 19.3 and averaged 19.0%. In individual trials, there was often a three percentage point spread in protein content among varieties. At the late trial in Lancaster, varieties ranged from 34.1 to 37.5% protein. Our results are consistent with those from the U.S. Soybean Export Council 2016 Commodity Soybean Quality Report, showing soybeans from the east coast region averaged 35.2% protein. This compared to 34.0% in the Western Corn Belt. This suggests that our soybeans tend to be slightly higher in protein than those from the Upper Midwest and with careful variety selection there could be a possibility of increasing protein content slightly if desired.
