Interpretive Summary: Since 1994 there has been a dramatic increase in conservation tillage and the use of cover crops. Information is needed by growers and crop consultants on management of cover crops in conservation tillage systems. This short review article presents information in summary form regarding the need for cover crops in cotton production systems, as well as proper seeding rates, seeding methods, and termination strategies for cover crops. It also discusses the advantages and disadvantages of small grain versus legume cover crops. Other management options, such as adjustments in nitrogen fertilization, and the use of row cleaners are also discussed. The information can serve as a readily available synopsis of management tips for growers, technical specialists and crop consultants involved in cotton production in the Southeastern and Midsouth regions of the Cotton Belt.

Technical Abstract: Cover crops are most beneficial in conservation tillage systems in regions with long growing seasons and mild winters and in cropping systems with a high proportion of low residue producing crops, such as cotton (Gossypium hirsutum L.) and soybean [Glycine max L. (Merr.)]. Cover crops are often needed on erodible land for effective erosion control in conservation tillage or no-till cotton systems. This short review article discusses seeding rates, seeding methods, and termination strategies for cover crops in cotton production systems. It also discusses the advantages and disadvantages of small grain and legume cover crops. Other management options, such as adjustments in nitrogen fertilization, and the use of row cleaners are also discussed.
