Oregon is the world’s leading producer of crimson clover (Trifolium incarnatum L.) seed. Recent research has reported that seed yield has been increased in cool-season grass and red clover (T. pratense L.) seed crops with the application of trinexapac-ethyl, a gibberellic acid biosynthesis inhibiting plant growth regulator (PGR) and lodging-control...
Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...
