Growth performance and yield of shallot result from different Trichoderma sp. Formulation and applications

Abstract The production of shallots has been decreasing, one the factors causing it is soil degradation that caused by continuously use chemicals. Thus damaging and killing natural enemies. Soil improvement can be done adding organic material, minerals, optimizing function biological agents. Trichoderma sp agents ability to degrade soil. This study aimed determine effect form different application methods on growth yield shallots. location research was in Maku village, Sigi district, Central Sulawesi, from November 2020 January 2021. method used a separate plot design with four replications, where main sp. (T), which consists three levels, namely, T1 = liquid (60 ml/bed) T2 solid (12 g/bed). size bed 3 m x 1 while sub-plot (C), namely C0 without giving; C1 bulb straight ground; C2 mix manure. results showed treatment significant plant height number leaves, but not significantly way application. While interaction two treatments have performance parameters. However, component, did show difference. Overall, best combination mixed
