To identify opportunities to exploit new barley phenologies and architecture types to further improve mixed farming production across variable growing seasons.
• At Giles Corner in 2024, grain yield was significantly higher in elite spring grain varieties compared to winter types with Neo CL (5.58 t/ha) and Titan AX (5.44 t/ha) being top performers.
• The yield of simulated grazed plots compared to un-grazed (control) achieved similar grain yields in majority of treatments.
• Improved harvest index in grazed plots helped maintain high grain yields compared to lower harvest index achieved in the un-grazed (control).
• The variety Beast was a top performer for early season DM production and total seasonal forage value compared to other varieties tested.
• The winter type variety Newton had three simulated grazes in the Up to Z (Zadocks) 30 treatment removing a cumulative total of 3.13 t/ha DM, prior to additionally yielding 3.39 t/ha of grain.
