Stem, Leaf, and Panicle Yield and Nutrient Content of Biomass and Sweet Sorghum
AGRONOMY JOURNAL, 110(5), 1659–1665.
Core Ideas Sorghum is a potential dedicated bioenergy crop both from biomass and sugar yields. Increasing rates of N fertilizer affected biomass yield and nutrient removal for sorghum cultivar ES5200 by partitioning resources primarily toward the stem component. For sorghum M81‐E, the seed head component accounted for a greater proportion of biomass, compared with sorghum ES5200, and biomass yield and nutrients were more evenly distributed among the three components. Returning the leaf and seed head components back to the field to enhance soil fertility has the potential to provide at least 45, 7, and, 26 kg ha−1 of N, P, and K, respectively.
