- ... Photoperiod-sensitive sorghum (Sorghum bicolor L. Moench) (PSS) has been identified as a potential bioenergy crop. However, little information is available for water and nitrogen (N) management in PSS in the Texas High Plains. The objectives of this study were to optimize water and N management for improving biomass yield, and to maximize water and N use efficiency in PSS. Two field experiments we ...

- ... The nitrogen use efficiency (NUE) of high biomass energy sorghum hybrid plants increased during 180 days of growth to a maximum of 370 g DW g−1 N−1. Shoot N uptake was biphasic and continued for 120 days. Leaf N accumulation was rapid until day 60. Specific leaf nitrogen (SLN) varied from 0.9 to 1.7 g N m−2 green leaf area, a typical range for C4 grass canopies. Stem N increased to a maximum at da ...
