Enhanced Soybean Growth and Damping-off Disease Suppression via Trichoderma asperellum and Liquid Tofu Waste Co-application

Abstract This study aims to examine the inhibitory properties of Trichoderma asperellum Tc-Jjr-02 against Rhizoctonia sp. Rz-Sd05, and associated effects its combined application with liquid tofu waste on damping-off disease in soybeans, as well vegetative growth parameters plant. An vitro dual-culture technique was employed for inhibition test, while vivo plant were examined using a factorial Randomized Block Design. Observational variables included symptom index, height, leaf number, dry weights shoot root. The T. found inhibit Rz-Sd05 by 58.52 ± 4.12%, reducing symptoms up 69.8%. Furthermore, co-application significantly improved soybean’s growth, leading increases 27.3-35.8% 16.1-25.2% numbers, 31.3% 47.5% root respectively, compared control conditions. These findings suggest that can effectively mitigate enhance soybean providing sustainable approach improving crop health yield.
