My colleague Dr. Brenda Ortiz from Auburn University recently had a paper published in Nature about climatic effects on maize yield in the Southeast that you might find interesting.  You can read the article, entitled “Climate Change and ENSO Effects on Southeastern US Climate Patterns and Maize Yield”, at https://www.nature.com/articles/srep29777.  Keep in mind that it is a journal article so a bit more formal than most of the popular press articles I post here.  In the article she and her coauthors discuss the variations in yield caused by changes in El Niño phase as well as trends in temperature over time.
