Escalating corn prices have induced growers to consider deviating from a traditional 50-50 corn-soybean (CS) rotation to either a corn-corn-soybean (CCS) or a continuous corn (CC) cropping sequence.



It is not clear how yields of both crops respond to a CCS rotation, and what management factors might alleviate some of the yield penalty for corn when it follows corn. For this reason, field studies were conducted at six widely contrasting locations in Illinois in 2004-2006 to measure the effect of CC, CCS and CS rotations on the yield of corn and soybean.



Pioneer Hi-Bred's Crop Insights 58 reports the results of those studies.
