Anthocyanin content, phenolic content, antioxidant activity and yield in indigenous rice as affected by different fertilizers

Abstract. Prajuntasan R, Ratananikom K, Payoungkiattikun W. 2022. Anthocyanin content, phenolic antioxidant activity and yield in indigenous rice as affected by different fertilizers. Biodiversitas 23: 4195-4201. This study was to evaluate the effects of fertilizer management methods (organic inorganic) on total anthocyanin content (TAC), (TPC), activity, eight local varieties. A 2×8 factorial experiment a randomized complete block design with three replications setup farmer’s farm. Organic increased TAC, TPC but significant increases were found for TAC,and activity. The highest TAC Luem Puew, Kum Puen Baan had TPC. TPCvarietiesdid not necessarily havethe Sung Yod, Chaow Daeng, Ka Dum this parameter. Puew + organic treatment combined TAC. Still, result activities several combinations associated most varieties except Nang Nuan Mali Nga Chang.
