Ethephon is commonly used in mid-Atlantic barley production to reduce plant height and lodging, but is known to reduce grain yield and test weight in some barley cultivars. Management practices that produce high yield and good grain quality in traditional mid-Atlantic winter barley have yet to be evaluated for hulless barley. This research examined response of three winter hulless barley genotypes to ethephon plant growth regulator (PGR) and provides recommendations for appropriate PGR rates.
