Currently, consumers are turning to healthy food. Using organic fertilizer instead of chemical fertilizer is another way to produce peanuts for a healthy diet. The objective of this study was to evaluate the effect of fertilizer types on yield components and total phenolic compounds in peanut. A completely randomized design with three replications was used. There were six treatments consisting of no fertilizer, chemical fertilizer (25 kg/rai), bio-pellet fertilizer (300 kg/rai), earthworm manure (1,000 kg /rai), fermented cattle manure (1,000 kg /rai) and fermented bat manure (1,000 kg /rai). Data were collected on stem dry weight, leaf dry weight, pod number per plant, seed number per pod, seed yield per plant, 100 seed weight, shelling percentage, harvest index and total phenolic content. The results found that fertilizers were significantly different for enhancing number of pod per plant, pod fresh weight, pod dry weight, yield per plant and 100 seed weight. The fermented bat manure was shown to significantly support pod dry weight, seed yield per plant and 100 seed weight, whereas chemical fertilizer increased harvest index. Besides, total phenolic contents were not significantly different among peanuts grew up with all fertilizers. However, high values were found in those with fermented bat manure, chemical fertilizer, and no fertilizer. This indicated that fermented bat manure could enhance yield components and has a trend to increase total phenolic contents in peanut.
