Acknowledgments
  • Know your growth stages. Application timing of plant growth regulators (PGRs) in barley could prove key at harvest.
  • Understand the lodging risk of your varieties prior to PGR application, it may not be necessary.
  • Nitrogen application rate had no effect on PGR application response in barley.
