Field trials were conducted during the 2013 and 2014 growing seasons to evaluate factors that impact yields of irrigated grain sorghum in Arkansas.  Trials were located in the Mississippi river delta region of eastern Arkansas near Marianna and Rohwer.   Factors evaluated included deep tillage, increased plant populations, in-furrow starter fertilizer, additional fertilizer beyond normal recommendations, and foliar fungicides.  All factors were evaluated individually and then all factors were combined together into a single treatment to evaluate impact on grain sorghum yield when all factors were combined.  Several factors increased grain sorghum yields individually including deep tillage and foliar fungicides, but when all the factors were combined together, yields were increased greater than any single factor did.
