Interpretive Summary:

Technical Abstract: Row crop growers in the Southeastern United States are in a need to diversify their cropping systems and increase profitability. Brassica carinata could be a likely candidate to replace the significantly large winter fallow acreage in this region. Fitting carinata into existing crop rotations will provide growers with additional income. However, carinata is a relatively new crop in the region, and this necessitates the need to investigate rotations that are economically and agronomically feasible. To address this, a study was conducted to evaluate the effects of previous summer crops (Peanut - Arachis hypogaea, Cotton - Gossypium hirsutum L., 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 seven replications (3 irrigated; 4 non-irrigated) was implemented in Jay, Florida. Preliminary results from this trial will be presented.
