Biomass yield and water‐use efficiency in photoperiod‐sensitive sorghum genotypes in the US Southern Great Plains

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Photoperiod‐sensitive (PS) sorghum [Sorghum bicolor (L.) Moench] has been developed as a bioenergy crop. However, little is known about PS sorghum production in semiarid environments. The objective of this study was to investigate water use, biomass yield, and water‐use efficiency (WUE) in recently developed PS sorghum genotypes.
