Study Shows SUPERU® Premium Fertilizer Improves Grain Yield in Winter Wheat

In a recent study published by Agronomy Journal, a team from the Texas A&M AgriLife Research Center at Vernon compared the effects of two enhanced efficiency fertilizer technologies, SUPERU® fertilizer and a polymer-coated urea (PCU), against untreated urea at different application rates, timing and two soil types on dryland winter wheat. Results found SUPERU has the potential to improve wheat grain yield and protein concentration relative to untreated urea.
Research Data 

Wheat fertilized with SUPERU at 63 lb. N/acre at-planting achieved 26 percent greater yield than untreated urea. Yield improvements with the use of SUPERU were associated with greater grain nitrogen uptake efficiency and protein content.

Based on the collected data in the study, SUPERU was successful at accelerating early-season crop development and sustaining it over the growing season. Substantial early-season growth plays an important role in achieving higher yields in winter wheat. Likewise, having enough nitrogen available for a crop through the end of the growing season is critical to yield.

SUPERU fertilizer increased wheat yield by 26 percent compared to untreated urea.1

 
Wheat_Yield_Benefit_SUPERU_Chart[8]

SUPERU fertilizer increased wheat yield by 26 percent compared to untreated urea. Due to the dryland conditions and the risk of volatilization, it is likely the urease inhibitor in SUPERU was the primary contributor for the yield advantage.

 
Research Data 

The economic analysis of net profit for each treatment was at the wheat price points of $4.00, $6.00 and $8.00/bu., which represent the low, average and high prices in the Southern Great Plains over the past eight years. 2Broadcasting SUPERU resulted in higher net profits than untreated urea at all price points. As wheat price increased, the crop treated with SUPERU saw more economic benefit. By protecting the nitrogen investment with SUPERU, the study showed an increase in yield, resulting in an increase in net profit by $37.10 per acre compared to untreated urea.

The study concluded the winter wheat fertilized with SUPERU consistently increased yield and net profits over wheat fertilized with urea.

With roughly 90 percent of the winter wheat in the ground, growers should soon be planning their winter top-dress applications. While crop progress and weather conditions vary, the 4Rs of fertilizer application pertain across the wheat belt.
