This study aimed to investigate the effects of 3-isolates of Trichoderma asperellum on the yield of pink garlic (Allium sativum L.) and its secondary metabolites. Yield parameters (bulb weight, clove weight, and number of cloves), were measured. Additionally, polyphenol flavonoids and antioxidant activity were determined, and functional components were identified using FTIR. The experiment consisted of 3 following treatments: T1 (TMSKOLDZ20), T2 (TMS11DZ15) and T3 (TMS5DZ150). The results indicated that the treatment T1 of Trichoderma isolate was the most effective in promoting garlic yield, while the treatment T3and T2 of Trichoderma isolates improve the total phenol, total flavonoid and antioxidant activity in garlic cloves. Further more only the treatment T3 showed additional absorption region compared to treatments. In conclusion, Trichoderma isolates tested in this study have the potential as bio-stimulants for promoting yield and secondary metabolites.
