Georgia is a leading fresh market cabbage ( Brassica oleracea var. capitata ) producer. Current recommendations for bare-ground grown in the Coastal Plain of indicate 175 to 225 lb/acre nitrogen (N). Approximately one-third N fertilizer recommended at planting, with two or three additional side-dress applications during season. Growers have begun banding liquid between four and six times season reduce leaching enhance productivity. To determine validity current as well efficacy applying periodic throughout growing season, field experiments were conducted Tifton, GA Fall 2016 2017 cultivar Cheers. Fertilizer rates 175, 200, 225, 250 applied using equivalent preplant (50 N) posttransplant granular (27–0P–0K–5Ca) (9N–0P–0K–11Ca). A factorial, randomized, complete block design was used. There no interactions among program, rate, year yield nutrient concentrations. Total unaffected by rate. However, plants fertilized lowest rate (175 had yields from first harvests compared other rates. Nutrient concentrations affected year, having greater most macronutrients 2016. In conclusion, application led potential delay harvest, but all equal. The method did not impact earliness, suggesting that after planting are adequate.
