Weed Management and Economics in Cotton Tillage Systems in the Texas High Plains

Field studies were conducted in 2007 and 2008 to evaluate cotton weed management in no-tillage, strip-tillage and conventional tillage following grain sorghum. Within each tillage system, there is 16 preplanned treatments that vary in the overall herbicide inputs.  Some of the treatments contain up to four residual herbicides, whereas others contain no residual herbicides.  Results will include initial cotton stand, weed control by species, input costs, yield, and net returns above weed control costs.
