Over the past two years, NSA and SD Oilseed Council have funded research that provides new N and P recommendations based on general productivity history and not a yield prediction model. N and P recommendations are based on both documented yield responses to each and economic analysis.

If you are interested in reading the NDSU Fertilizing Sunflower Circular SF713 with the new recommendations, you can access it using this link: http://www.sunflowernsa.com/growers/Production-Resource-Books/

In addition, Dave Franzen from NDSU has just developed a ND sunflower N calculator that is available on the NDSU website that you may find useful as well.  The address is: https://www.ndsu.edu/pubweb/soils/sunflower/
