Cultural Management System and Weed Control in Upland Fields

Cultural practices favoring the crops are one of the excellent weed control measures in upland crops. The primary cultural method for weed-management may include planting of weed-competitive cultivars, proper planting time and spacing, optimum rate and placement of fertilizer, crop rotation, mulching, and timely tillage. However, cultural method must be applied as a part of the program along with all other available means for controlling weeds since this method alone is not adequate. The efficient and economical weed control can only be achieved by combinating cultural, mechanical method that supplement each other into a weed management system. Intelligent selection of weed control, however, presuppose knowledge of the life history and growth requirements of the weed and its interaction with the environment.
