Abstract

The rapid adoption of glyphosate‐resistant cotton ( Gossypium hirsutum L.) has presented growers with alternative technologies for no‐till cropping systems. No‐till cotton following a wheat cover crop was compared to no‐till cotton without a cover crop in nine paired fields in Mississippi. A wheat cover crop was found to significantly increase the yield of no‐till cotton an average of 11.96% or 110 lbs of lint per acre. The net value of the average response of no‐till cotton to a wheat cover crop was estimated to be $48.95/acre. Wheat as a cover crop improves the yield and profitability of no‐till cotton.
