Core Ideas During the 4‐yr period of this trial, N fertilization increased dry matter yield in 2 out of 4 yr for biomass sorghum and there was no effect on dry matter yield of sweet sorghum. High DM yield supports sorghum as a bioenergy crop, however, the relatively low nutrient removal rate may limit its utilization in nutrient‐rich environments such as spray fields. Greatest dry matter yields achieved were ∼18.5 Mg ha−1 at a N fertilization rate of 67 kg N ha−1 yr−1 for biomass sorghum.
