NET REVENUES OF POTATOES ROTATED WITH OTHER CROPS

Using actual potato production data from Aroostook County, Maine, we i nvestigate the possibility of producers increasing net revenues by mod ifying rotation practices. By examining rotations as a whole, and inco rporating yield effects and changes in production costs across rotatio ns, more realistic pictures of net revenues for each rotation develop than if net revenue for each crop within a rotation is considered inde pendently. Our analyses indicate producers can alter their production practices within the range of rotations used locally to increase net r evenues. A key finding confirms the synergistic interaction between gr ains underseeded with a green manure crop and round-white potato varie ties, resulting in decreased production costs, greater potato yields, and increased net revenues.
