The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...
