To assess three rotations used in the Mid-North, especially those incorporating export hay or ocntinuous cereals.
Key messages
Wheat following wheaten hay produced the highest grain yield, averaging 3.22 t/ha.
The highest gross margin for the 4 years was from the standard rotation, which included field peas and canola.
The greatest limitation to rotation productivity was from brome and barley grass, especially in the continuous cereal rotation.
