Results of a study designed to evaluate 14 different combinations of cotton production practices were presented. Production practices included in the study were various combinations of disking, subsoiling and chiseling. Disk applications of trifluralin were also evaluated. Yields obtained from each of the tests were compared to a check which represented a conventional cotton production system without deep tillage. Partial budgets were prepared for each production system. Each production system was evaluated and ranked on the basis of increased yields and increased returns above the costs of performing selected tillage and weed control operations
