2017 PFR Proven™ Wheat Products and Practices

Published on Wednesday, December 06, 2017

One question we get asked a lot is how we apply nitrogen (N) on our wheat acres. What we have observed in Practical Farm Research (PFR)® is that, regardless of the source of N applied, split applications pay. Some of the benefits of split applications include increased yield, increased N efficiency, and the potential for lower environmental losses.

Similar to split applying our N applications on corn, split applying on wheat allows us to split our risk. The split application allows N to be applied closer to the physiological stage where the plant will take up the N. With this being the case, we can likely expect a greater portion of applied N to be utilized, thereby improving our N use efficiency.

Our six-year, multi-location data has shown that split applying UAN at Feekes 3 and Feekes 5 has provided an average increase in return on investment (ROI) of $17.24/A. over a single application.

 

Split applying urea has provided increased returns as well. In fact, over the same six-year period, split applications provided an average ROI increase of $22.13/A. Similar to the UAN study, these applications were also made during Feekes 3 and Feekes 5.

 

 

With six years of solid data favoring split applications of UAN and urea, this practice was given the PFR Proven stamp in 2017.

Another practice we have seen pay off in wheat is applying fungicide at Feekes 10.5.1 or flowering. This growth stage typically begins 1.5 to 2 weeks following flag leaf ligule visibility and lasts, on average, up to five days. Fungicide applications at this growth stage are most often applied to target Fusarium head scab, as flowering is when the earliest onset of this disease has been observed. Fusarium head scab has shown to result in yield losses of up to 45 percent, so applications at this timing are crucial. However, we have also seen yield gains with this PFR Proven practice, even in the absence of Fusarium head scab disease pressure. 

To date, the three fungicide products labeled as PFR Proven in wheat are Palisade® EC, Caramba®, and Prosaro® 421 SC.
