Grain sorghum is grown in Arkansas as a low input crop, often under non-irrigated conditions and in “marginal” land, such that the state average yield oscillates between 80 – 85 bu/A (less than 5000 lb/A). However, yields from fields enrolled in the Research Verification Program have been as high as 150 bu/A (> 8000 lb/A). Grain sorghum rotational benefits in fields where nematodes may limit yields, in addition to uncertainties associated with the potential impact of soybean rust has created a renewed interest in this crop. This paper presents results from several studies aimed at maximizing the yield potential of grain sorghum.
