To evaluate the effects of break crop species on the yield of subsequent wheat crop.
Key messages
The grain yield of wheat sown after pulses were 300 kg/ha higher on average compared to wheat sown after canola. The yield gap between the canola-wheat rotation and canola-pulse rotation was a result of reduced soil nitrogen levels following harvest of the break crop phase in 2018.
