Native Microbial Consortia: A Sustainable Strategy for Improving the Quality of Forest Seedlings in the Peruvian Amazon. Forests, 16(2), 309. doi: 10.3390/f16020309http://hdl.handle.net/20.500.12955/2655Forest plantations represent an alternative to reduce timber extraction pressure in the Amazonian forests. In order to tolerate the hostile field conditions of deforested areas, high-quality seedlings are required. This study aimed to find the optimal dose of a native microbial consortium (NMC), which enhances seedling quality indicators, in three forest species at nursery phase. A completely randomized design (3 × 5) was used. Factor 1: Bolaina blanca (Guazuma crinita Mart.), Capirona (Calycophyllum spruceanum Benth. Hook. f.), and Marupa (Simarouba amara Aubl.). Factor 2: Incremental doses of 0, 160, 320, 480, and 640 mL NMC per plant. The nursery survival (%), robustness index, root height/length ratio, shoot–root index, Dickson Quality Index (DQI), Nitrogen (%), Phosphorus (%), and Potassium (%) content in tissues were analyzed. Statistical analyses consisted of two-way ANOVA per variable and correlation analysis. The results indicated that increasing doses of NMC did not improve nursery survival for any species; did not decrease the robustness index, plant height/root length ratio, or the shoot–root index for any species; and did not increase the DQI, P%, or K% for any species; however, they did increase the N% for all species. In conclusion, the incremental dose of 160 mL was chosen for increasing the N% without affecting nursery survival.application/pdfenginfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by /4.0/Shoot–root indexRobustness indexDickson quality indexsurvivalGuazuma crinitaCalycophyllum spruceanumSimarouba amarainfo:eu-repo/semantics/articlehttps://purl.org/pe-repo/ocde/ford#4.01.02https://doi.org/10.3390/f16020309Sustainable forest management
