Growth termination of cover crop has been a subject of many studies. In no-tillage production, the cover crops are killed either by the contact herbicides, or by a mixture of nonselective and residual preemergence herbicides. Sustainable production systems aim at reducing chemical inputs so mechanical methods have been used. The success of any of these methods in cover crop termination depends on the growth stage of the cover crop at the time of killing, the type of cover crop, and the subsequent crop being planted. This study aimed to evaluate the use of cover crops for no-tillage production of sweet corn, compare the mechanical and chemical termination practices, and assess the influence of cover crops on weed suppression.
