Rotational Cropping Sequence Affects Yield of Corn and Soybean

R. K. Crookston; J. E. Kurle; P. J. Copeland; et al. Agronomy Journal 1991. doi:10.2134/agronj1991.00021962008300010026x

Other claims from this paper (10)

Intervention effect Annually rotated corn yielded 10% better than corn under monoculture.
Intervention effect First-year corn yielded 15% better than corn under monoculture.
Intervention effect Annually rotated soybean yielded 8% better than soybean under monoculture.
Intervention effect First year soybean yielded 17% better than soybean under monoculture.
Intervention effect With monoculture of corn, alternating two cultivars annually gave the same yield as continuous cropping of one cultivar.
Intervention effect With monoculture of soybean, alternating two cultivars annually gave the same yield as continuous cropping of one cultivar.
Observation The lowest corn yield came from second year corn.
Observation The lowest soybean yield came from extended monoculture.
Observation Soybean dry weight was not affected by cropping sequence.
Recommendation A superior cropping sequence for Minnesota would include at least three, and possibly more, crops (authors' recommendation).
