This year, a total of 15 studies were conducted across four of our six Practical Farm Research (PFR)® sites, as shown below. As a result of these studies, we have identified two new PFR Proven™ products, based on their yield results and return on investment (ROI). With all four sites having completed wheat harvest, our team is moving quickly on the 2017 PFR Wheat Book, and we can’t wait to share the results with you. In the meantime, we have highlighted some of the information below.
Plant Growth Regulator Study - Palisade® EC
The plant growth regulator study was conducted at both the Kentucky and Southern Illinois sites in 2017. Palisade® EC was applied at Feekes 5 a rate of 6 or 12 oz., with a nitrogen (N) rate of 120 units/A.
The teams observed differences in plant height measurements, taken at harvest, based on treatment as shown below.
The addition of Palisade EC to N applications at Feekes 5 showed both a yield increase and a positive ROI at both sites in 2017. When applied at a rate of 6 oz./A., Palisade EC resulted in a yield increase of
7.4 Bu./A. while the 12 oz./A. resulted in a 10.4 Bu./A. increase. These results support that applications of Palisade EC create more energy for reproductive growth over vegetative growth. This is demonstrated with the trend line below.
With three-year, multi-location data showing an average yield increase of 6.3 Bu./A., and an ROI increase of $15.31/A., an application of 12 oz./A. of Palisade EC with N at Feekes 5 is now considered to be PFR Proven.
Fungicide Study - Prosaro® 421 SC
Over the last four years, Beck’s PFR has tested fungicide applications in wheat at flowering, or Feekes 10.5.1. Fusarium head blight was specifically targeted at the time of flowering because the onset of this disease begins at that time and can be detrimental to yield in years of heavy infection. Not only does Fusarium head blight cause yield loss, but there is also a high likelihood of vomitoxin being present with this disease. As disease and vomitoxin levels increase, so do the odds of having an unmarketable wheat crop.
In 2017, this study was tested across four PFR sites, including Indiana, Kentucky, Ohio, and Southern Illinois. While none of these sites observed Fusarium pressure in 2017, other diseases such as powdery mildew (shown below) were present. Prosaro® 421 SC was able to suppress this disease and increase yields.
Multi-year, multi-location data has shown a yield increase from the use of a 6.5 oz. rate of Prosaro at flowering. Yield increases have even been observed in years and at locations in the absence of Fusarium head blight, ranging from a 2 Bu./A. increase to upwards of 12 Bu./A. With an average 6.1 Bu./A. increase across four years, and positive ROI results (shown below), Prosaro 421 SC was also named a PFR Proven product in 2017.
Be sure to check out these results along with results from our 13 other wheat studies in the 2017 PFR Wheat Book, which will be available in early August.
