“…This type of tobacco is used to obtain layers for the elaboration of Cuban cigars and strong cigarettes. Among the cultivars that are established on the island, Havana-2000 has excellent advantages in terms of its edaphoclimatic adaptability, tolerance to pests and diseases; as well as it has a potential yield of 2.33 t.ha -1 , and it adapts well to the forms of covered cultivation, sun-curing (involves simply drying the leaves uncovered in the sun) and with indirect sunlight (Sosa-Sánchez et al, 2022).…”

Tobacco is a crop of economic importance in tropical countries; it generates significant income in small agricultural areas. Within the agrotechnical activities that are carried out on this plant, biofertilization with Autochthonous Microorganisms (AM) represents a viable option for production with low inputs. Therefore, the objective of the research was to determine the biofertilizer effect of AM on black tobacco cv. Havana-2000. The experiment was carried out on a farm located in Los Cayos, Yara, Granma, Cuba, during the period November-February/2021. For this, the yield variables and the components were measured in the field. Statistical processing was performed using ANOVA and principal component analysis. The AM recorded four groups of microbes: bacteria (7x1012 CFU.mL-1) Lactobacillus sp. and Rhodopseudomonas sp., the fungi (3x1011 CFU.mL-1) Trichoderma sp., Aspergillus sp. and Penicillium sp., the yeasts (2x1011 CFU.mL-1) Saccharomyces sp. and Candida sp. and the actinomycete Streptomyces sp. (1x1010 CFU.mL-1). In the field, the AM biostimulated between 15 - 82 % of the yield and the components, achieving the best results at the dose of 36 L.ha-1. Finally, the importance of using AM as an organic alternative for tobacco biofertilization is demonstrated.
