Abstract

This study analyzed the effect of drought stress on flavonoid and phenol content in Mandau sorghum varieties. The experiment used a completely randomized design to use four irrigation patterns (daily, every 4, 5, and 6 days). The results showed that drought stress had a significant effect on phenols but not on flavonoids. The highest flavonoid (580.0 µg/g) and phenol (2555.0 µg/g) contents were obtained with watering every 4 days, while the lowest flavonoid (395.0 µg/g) was obtained with watering every 5 days. Phenols increased with stress intensity, while flavonoids tended to decrease under severe stress. Mandau sorghum has potential as a source of bioactive metabolites for natural bioherbicides and sustainable agriculture
