Adoption of soil conservation practices has been promoted to improve environmental and economic benefits across the United States. These practices are especially necessary for soil health improvement in the Southern High Plains where soils are prone to erosion and agricultural irrigation relies heavily on groundwater. Winter cover crops and notill cropping are two conservation practices for reducing soil erosion, but producers might face additional risks associated with adopting these practices. The objective of this study was to examine the profitability and risks associated with alternative tillage and cover crops (no cover crop, winter wheat [Triticum asestivum L.], and grasslegume mixture) for irrigated cotton (Gossypium hirsutum L.). Using data from a 6yr field experiment, net return distributions of each production system were evaluated and ranked across various risk aversion levels. The results showed that the average net returns were $1040 and $1049ha for conventionally tilled and notill cotton without a cover crop, while the net returns were $1121 and $1075ha for notill cotton with wheat and mixed cover crops, respectively. Producers adopting cover crops had a greater probability of getting a middle interval of net returns between $760 and $1370ha. The results of risk analysis show that riskneutral and slightly riskaverse producers prefer notill cotton production with wheat cover, while notill with mixed and wheat cover are the first and second most preferred systems for very and extremely riskaverse producers. Sensitivity analysis confirms consistent profit effects of cover crops and notill adoption at multiple cotton price levels.
