This article presents views on seedling rates, as well as precision agriculture equipment, winter weeds, cover-crop termination and other cotton industry issues as of March 2005. Conservation tillage now occupies about 40 percent of the cotton acreage in Georgia. Critical to success in conservation tillage is the elimination of existing vegetation prior to cotton establishment. Some weeds, particularly cutleaf eveningprimrose and horseweed, are very difficult to control burndown treatments in April and May. A simply and incredibly effective solution to cold season bradleaf weeds is an application 2,4-D in February or March. Rates as low as one pint per acre are effective on primrose, while higher rates are necessary for horsewood. Meanwhile, as input costs continue to rise, Alabama cotton farmers have been looking for ways to become more efficient. Alabama research has shown that cotton yields can be increased by an average of about seven percent when cotton row spacing is reduced from 40 to 30 inches. The cotton middles are closed sooner in 30-inch rows, and the shading reduced weed competition. This system requires timely application of herbicides and growth regulators early in the season and also the equipment to harvest this close row spacing. |
