Effects of Fertilizer Application and Successive Harvesting on Clipping Yield, Phytochemical Contents and Antioxidant Activity of Cynodon dactylon (L.) Pers.

The present study aimed to investigate the effects of fertilizer application and successive harvesting on phytochemical contents and antioxidant activities of Cynodon dactylon, a medicinal Bermuda grass in Sabah (Malaysia). Three fertilizers of two nitrogen concentrations were used in the experiment...
