Conteúdo: | Organic compounds from the compost of agricultural waste have been increasingly used in the formulationof substrates for fruit seedlings production. Microorganisms can enhance the beneficial effects of fertilizerson the plant, but reports on the use of endophytic strains to promote banana plant growth are rare. The goalof this study was to investigate the ideal mixture of soil and organic compound withBacillussp. andTricho-derma asperelluminoculations for optimal growth and nutrient content of banana seedlings. A Greenhouseexperiment was arranged in a factorial scheme (3£2£2)+3,five times replicated, with the following fac-tors: (a) substrates consisting of three organic compound and soil ratios20:80, 40:60, 60:40 (v/v); (b)Bacil-lussp. inoculationwith [B+] and without [B-]; and (c)Trichoderma asperelluminoculationwith [T+] andwithout [T-]. Additionally, the following controls for substrates consisting of soil free of organic compound(0:100) were also considered: [B+T-], [B-T+], and [B-T-]. After 100 days from planting, plant height (H), pseu-dostem diameter (D), H/D ratio, number of leaves, total leaf area, root volume, shoot and root dry mass, netphotosynthesis, and contents of chlorophyll, carotenoid, nitrogen (N), phosphorus (P) and potassium (K)were evaluated. Results showed that the substrate 40:60 withBacillussp. orTrichoderma asperelluminocula-tion provides the best morphophysiological quality to banana seedlings. The strains also showed potential topromote plant growth in different ways, either by helping phosphate solubilization or by favoring auxinsand hydrolytic enzymes synthesis.
