Interpretive Summary:

Technical Abstract: Row crop growers in the Southeastern United States (SE US) are interested in diversifying their cropping systems and increase profitability by growing a cash crop in between summer crops, typically cotton (Gossypium hirsutum L.) and peanut (Arachis hypogaea L). Double cropping Brassica carinata between summer crops has the potential to increase grower profitability and increase land use efficiency in the region. However, carinata is a relatively new crop in the SE US, and its successful establishment in the region relies on its rotational fit into existing cropping systems. This necessitates the investigation of rotations that are economically and agronomically feasible. To address this, a study was conducted to evaluate the effects of previous summer crops (peanut, cotton, and summer fallow) on carinata production, as well as the effects of carinata production on subsequent summer crops (peanut, cotton, soybean – Glycine max, and sorghum - Sorghum bicolor). A randomized complete block design with a split-split plot restriction on randomization with eight replications (4 irrigated; 4 non-irrigated) was implemented in Jay, Florida. Preliminary results from this trial will be presented.
