Various cultivation practices did not significantly increase the total phenol content (TPC), antioxidant activity (AA), and calcium (Ca) content in Chinese kale (Brassica oleracea). The results indicated that conventional cultivation (CC), good agricultural practice (GAP), and local plant bioextract (LPB) significantly gave the highest leaves chlorophyll content at 23 and 48 days after seed sowing (DASS), fresh weight/m2, and leaves width compared to the controlled treatment. The highest leaves length was affected by GAP and LPB, where the highest petiole length was affected by GAP compared to other treatments. The TPC, AA and Ca content were not affected by any cultivation practices. These results implied that cultivation practices influenced some growth traits of B. loeracea but did not influence the TPC, AA and Ca content
