“…The chemical and microbiological characterization of an organic fertilizer, based on the use of residues from the harvest of bananas, showed that the greatest presence of microorganisms found were bacteria, although the genus was not identified [20]. The finding in this research is very important, due to the role of bacteria of the genus Bacillus, associated with the promotion of plant growth and control of pathogens [21][22][23][24][25]. A relevant aspect that distinguishes the bacteria of this genus is the ability to produce endospores, as a resistance mechanism to various types of stress [24,26,27].…”

Short CommunicationIn the production of plantains and bananas, as in most of agricultural production systems, large amounts of residues or waste are generated, such as reject fruits, pseudo-stems, leaf litter and rachis, mainly. In this regard, investigations carried out in Cuba, considering an average value into the percentage of rachis weight (11%) and its representativeness at the annual level production of plantains and bananas in the country (675,405.1 t), can mean values of 74,294.6 t of cluster rachis. These data reaffirm that the production of plantains and bananas in Cuba, causes a considerable amount of organic waste, which are not properly used and they could be reused [1].The Food and Agriculture Organization of the United Nations (FAO) promotes experiences in Latin America and the Caribbean, focused at reducing food loss and waste, and the use of by-products or residues, which contribute to the improvement of environmental health conditions in the context of integrated and efficient productive systems [2]. Leachates from edible musaceae (plantains and bananas) are plant extracts, obtained by decomposition of harvest residues [3,4]. The rachis leachate (flower peduncle, also known as pinzote or stem, has a helical shape and it is the responsible for the support of clusters), as it is a product of the same plant, it has essential nutrients (N, K, Fe, Mn, Na, Cu) that can be reused for the crop itself [5][6][7]. These plant extracts applied to banana seedlings under nursery conditions, have proven to be effective in the growth of them, with a significant increase in the variables (height, number of leaves, as well as the total length and fresh and dry weight of the roots) [8,9]. Besides the nutritional value of this extract of plants, its potential as a pest and pathogen controller has been studied.

“…A partir de la aplicación del tratamiento se tomaron mediciones diarias del largo del tallo y número de foliolos por 60 días. En el día 60 se evaluaron: largo de raíz, peso húmedo de plántulas, peso húmedo de raíz, peso seco de plántula, peso seco de raíz, peso húmedo de tallo y hojas, porcentaje de humedad de plántulas y porcentaje de humedad de raíz (Gómez-Luna et al, 2012;Mena-Violante et al, 2009;Airola, 2010). El experimento fue realizado bajo un diseño ANOVA completamente al azar con un nivel de significancia de 0.05 y comparación de medias de Tukey.…”

“…After the treatments, we took daily measurements along the stem and the number of leaflets on those 60 days. On day 60, we assessed root length, seedling wet weight, root wet weight, seedling dry weight, stem and leaves wet weight, seedling moisture percentage and root moisture percentage(Gómez-Luna et al, 2012;Mena-Violante et al, 2009;Airola, 2010). The experiment used a fully randomized ANOVA design, with a significance level of 0.05 and Tukey's mean comparison test.The three strains of B. subtilis were capable of producing siderophores, as demonstrated by the halos in CAS media(Figure 1).…”

Objective: To investigate the efficacy of plant growth-promoting rhizobacteria (PGPR) in enhancing the early development stages of Schizolobium parahyba, a critical species for the timber industry, aiming to optimize reforestation and agroforestry practices for sustainable forestry. Theoretical Framework: The research is grounded in the exploration of symbiotic relationships between PGPR strains and plant species, focusing on their potential to improve seed germination, plant growth, and biomass production. The study examines how these interactions can be leveraged to enhance agricultural productivity and sustainability, with a specific emphasis on the benefits of employing PGPR in forestry. Method: The study utilized an experimental approach, assessing the impact of four PGPR strains (Serratia marcescens, Pseudomonas protegens, Enterobacter absuriae, and Acinetobacter calcoaceticus) on S. parahyba seedlings. These were cultivated in three different substrates, with variables such as germination rate, above-ground and root growth, and biomass production meticulously measured to evaluate the effects of bacterial inoculation. Results and Conclusions: The application of PGPR notably improved all measured growth parameters in S. parahyba seedlings, with A. calcoaceticus and P. protegens specifically enhancing stem and root development, respectively. A synergistic effect was observed in substrates containing peat, underscoring the significant potential of PGPR in boosting the productivity and sustainability of early-stage forestry cultivation. The findings advocate for further field studies to fine-tune these interactions, aiming to establish more resilient and ecologically sustainable agricultural practices. Originality/Value: This research contributes novel insights into the utilization of PGPR in forestry, highlighting its substantial promise in enhancing the early growth stages of Schizolobium parahyba. By demonstrating the specific benefits of PGPR strains and their interactions with different substrates, the study offers a promising strategy for improving the sustainability and productivity of reforestation and agroforestry efforts.
