The use of rhizospheric microorganisms as plant growth promoters has emerged as a sustainable alternative in agricultural management. Species of the genus Trichoderma are widely recognized for their ability to stimulate root development, enhance nutrient uptake, and modulate plant physiological responses. The aim of this study was to evaluate the effect of different doses of Trichoderma harzianum on the initial growth of three sugarcane varieties under greenhouse conditions. The experiment was conducted in a randomized complete block design, with three treatments plus a control without fungal application, and four replicates. The varieties evaluated were RB97-5952, RB97-5202, and CTC-9002. The treatments consisted of soil application of T. harzianum at rates of 0.75, 1.5, and 3.0 L ha⁻¹, in addition to the untreated control. Plant height and stalk diameter were measured at 30 and 60 days after planting, and at 90 days root fresh mass and shoot fresh mass were also evaluated. It was observed that the application of T. harzianum promoted significant increases in biometric parameters (plant height and shoot fresh mass) in the RB97-5202 and CTC-9002 varieties, suggesting that the responses depend on the genotype × dose combination. The results indicate a potential biostimulant effect of the microorganism on the initial development of the crop.
