“…A mechanical harvester was used to harvest seed cotton, and samples were ginned to obtain lint yield. Irrigation water was applied to meet 85% evapotranspiration replacement and equally applied to all the plots using a center‐pivot sprinkler system (Adhikari et al., ). The amount of irrigation water varied for each year depending on the precipitation and plant water demand.…”

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 no‐till 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 grass–legume mixture) for irrigated cotton (Gossypium hirsutum L.). Using data from a 6‐yr 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 $1049 ha−1 for conventionally tilled and no‐till cotton without a cover crop, while the net returns were $1121 and $1075 ha−1 for no‐till 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 $1370 ha−1. The results of risk analysis show that risk‐neutral and slightly risk‐averse producers prefer no‐till cotton production with wheat cover, while no‐till with mixed and wheat cover are the first and second most preferred systems for very and extremely risk‐averse producers. Sensitivity analysis confirms consistent profit effects of cover crops and no‐till adoption at multiple cotton price levels.

“…This region consists of 22 counties and borders Oklahoma to the north. The annual precipitation in this region ranges from 460 mm in the west to 760 mm in the east, and most precipitation occurs during May–September (Adhikari et al., ). Both dryland and irrigated cotton systems are widely practiced in this region (USDA‐ERS, ).…”

“…Winter cover crops are a form of habitat management that adds habitat complexity into cropping systems, and enhances multiple ecosystem services critical to sustainable crop production (Daryanto et al, 2018;Duzy & Kornecki, 2017;Adhikari et al, 2017). Cover crops are often planted to suppress weeds and reduce erosion, and provide several additional benefits such as improving soil health by fixing nitrogen, sequestering excess soil nutrients (Hartwig &Ammon, 2002), or sequestering atmospheric carbon and building soil organic matter (Kaye & Quemada, 2017).…”

A shift to more ecologically based farming practices would improve the sustainability and economic stability of agricultural systems. Habitat management in and around agricultural fields can provide stable environments that aid in the proliferation of natural enemy communities that moderate pest populations and injury. Winter cover crops offer a potentially cost-effective approach to improving habitat that supports natural enemy communities early in the growing season. We investigated the effects of winter cover crops including cereal rye (Secale cereal L.) and crimson clover (Trifolium incarnatum L.) on the abundance and diversity of natural enemies, key pest populations, biological control services, and cotton yield. Winter cover crops were established on 0.4 ha replicated field plots in the fall of 2017 and 2018. Suction sampling during each cotton development stage demonstrated that a rye cover crop promoted greater abundance and diversity of natural enemy communities in early cotton stages. Extensive leaf sampling of seedling cotton showed that cover crops significantly reduced thrips infestations. Furthermore, stink bug boll injury decreased on plots prepared with a rye cover compared to cotton lacking this additional habitat. Combining end of season yield results and management practices with an economic analysis of the costs of production, the value of cotton grown into a cover crop was cost competitive with conventional (no cover) cotton production. These results suggest that conventional growers utilizing cover crops could reduce insecticide inputs through natural reductions in pest pressure, and overall do not incur additional production costs.
