To compare the economic and agronomic response between the paddock rotations of wheat on wheat, wheat on late pasture topping and wheat on chemical fallow. This investigation aims to identify winter fallowing as a low-risk rotational strategy for low rainfall cropping systems in the North and Eastern Wheatbelt region of Western Australia.
