ABSTRACT:
Three tillage systems used in continuous cropping and rotations with wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] were compared. Experiment station yield data and annual price data from 1986 to 1335 were coupled with 1995 cost-of-production estimates to determine expected net returns for a typical dryland farm in south central Kansas. In general, risk analysis indicated that risk-averse managers preferred reduced-tillage systems. A rotation of reduced-tillage sorghum and no-tillage wheat was preferred by moderately risk-averse producers. A combination of reduced-tillage continuous sorghum and redtued-tillage continuous wheat was preferred by more risk-averse producers. Planting wheat and grain sorghum in a rotation provided a small economic advantage compared to planting a single crop of wheat or sorghum.
