Strategic water stress boosts lucerne seed economics
Key Takeaways
- A five-year commercial-field trial compared 31 lucerne varieties under three irrigation strategies.
- The high-stress treatment delayed watering until early leaf drop and generally produced the best seed yields.
- Researchers said the same high-stress strategy consistently delivered the highest gross margins.
- Moderate stress did not reliably outperform standard irrigation, and variety choice still mattered across seasons.
