Trichoderma spp fungus can be used as a biostimulant for plant agronomic characters. This study was aimed to determine the effect of Trichoderma spp isolate, dosage, and interaction on the growth of Samosir shallots. This study was carried out in Muara Subdistrict, North Tapanuli District, North Sumatra, Indonesia, from June to December 2021. This study used a factorial randomized block design with three replications, the first factor being the types of Trichoderma spp (T. harzianum, T. virens, T. viride, T. asperellum). The dosage of Trichoderma spp such as 0; 20; 40; and 60 g/polybag was the second factor. Parameters were processed using ANOVA followed by DMRT at P<0.05. The findings revealed that the higher ability of T. viride isolates to increase the plant height growth of Samosir shallots. The dose higher of isolated up to 60 g/polybag increased the plant height and number of leaves in Samosir shallots. The interaction of T. asperellum isolate at a dose of 20 g/polybag showed the highest number of leaves compared to other interactions.
Key words: agronomic / capability / dosage / Samosir shallots / Trichoderma isolates
