Rotation trials are continually evaluated. In 2017, a complete cycle of 1, 2, 3, and 4-yr rotations of peanut with different crop combinations with com, cotton, and grass fallow could be compared. The lowest yields and grades typically occur following shorter rotations, especially continuous peanut. In this cycle, differences among crop sequences within a length of rotation were also observed. Rotations where peanut was immediately preceded by co?? were more consistent in providing yield benefit than when peanut was preceded by cotton. Cotton is still considered a good rotation partner with peanut, but is best utilized in longer rotation sequence (three full seasons between peanut) or when immediately following peanut then replacing with com the year before switching back to peanut.
