This project will result in development of an unbiased unified set of soybean production recommendations for the entire US and for regional production areas, rather than the current state-by-state recommendations available through state Extension. Each of the three research projects will be conducted in two locations per state in each of the three years of this project. Up to 54 site-years of data will allow for the development of comprehensive regional and national soybean production recommendations. Other outcomes of this project include scholarly research focused on applied soybean production issues (articles in Corn and Soybean Digest, research journals, and information on Extension websites and blogs), and the education/training of graduate students to fill an ever-widening gap in the number of MS and PhD level graduates with direct soybean production experience.
