Results have been released from the 2015 Answer Plot Program by WinField, and the data shows a positive yield response to split-season and late-season nitrogen applications made at critical corn growth stages.

In the study, researchers compared the results of three different application scenarios. The two split applications observed in the study were made with the 360 Y-DROP applicator for precise placement at the stalk base.

Trial results, when compared to the total N application at planting, showed average yield increases of 9.4 bushels per acre with a split application at planting/V10, and 11.2 bushels per acre with a total N application at planting followed by additional N at VT.

“Our N trial not only demonstrates the importance of feeding the crop at the right time, it also showcases how advanced applicator technology can help get the most benefit from each application,” says Kevin Eye, vice president, agronomy and product development, WinField US. “These results verify that how we allocate inputs can have a big impact on bottom-line profits as well as the environmental costs of applying excess N.”

The 2015 trial results also reinforced the value of focusing input investments where they will deliver the greatest returns throughout the farm operation.

“To help farmers weather ongoing low commodity prices, we continue to focus our research on areas that will help farmers understand that prosperity in today’s market doesn’t necessarily come from spending less – it comes from spending smarter,” Eye notes. “As we evaluate new products and tools, we share objective, data-based insights that can help farmers be successful next season and beyond.”
