ABSTRACT. Bracantiga (Mimosa scabrella Benth) is a native leguminous specie from the south of Brazil, with great potential for commercial use. It can be used to recover degraded areas due to their fast growth, high adaptability and root nodule formation capacity. One alternative to reduce fertilization costs of seedlings production, are the plant growth promoting rhizobacteria. The fluorescent group of Pseudomonas is common at several plant rhizosphere. The objective of this work was to assess the growth stimulus of fluorescent Pseudomonas isolates at bracatinga seedlings. The seeds were inoculated with three bacterial isolates (CBSAL14, CBSAL18 and CBSAL05), genetically identified as Pseudomonas sp. They were previously grown in 50 mL of Luria Bertani medium for 48 h and then the seeds were submerged for 30 min in the suspensions. Subsequently, they were sown in tubes containing sterilized commercial substrate and kept in greenhouse for five months. From 61 days after sowing, seedling height and stem diameter were measured monthly. The CBSAL14 and CBSAL18 isolates promoted promoted increase in growth of seedlings height of inoculated individuals compared to control, suggesting their potential use as plant growth promoters. TÍTULO. Influência de Pseudomonas fluorescentes no desenvolvimento de mudas de Mimosa scabrella. RESUMO. A bracantiga (Mimosa scabrella Benth) é uma leguminosa nativa do sul do Brasil, com grande potencial para uso comercial. Pode ser usada para a recuperação de áreas degradadas, devido ao seu rápido crescimento, alta adaptabilidade e capacidade de formar nódulos. Uma alternativa para reduzir custos de fertilização na produção de mudas, é o uso de rizobactérias promotoras de crescimento de plantas. O grupo fluorescente de Pseudomonas é comum nas rizosferas de diversas espécies de plantas. Neste trabalho, o objetivo foi avaliar o estímulo de isolados de Pseudomonas fluorescentes nas plântulas de bracatinga. As sementes foram inoculadas com três isolados bacterianos (CBSAL14, CBSAL18 e CBSAL05), geneticamente identificados como Pseudomonas sp. Foram, previamente, cultivados em 50 mL de meio Luria Bertani por 48 h, submergindo as sementes, na sequência, por 30 min nas suspensões. Posteriormente, foram semeadas em tubetes contendo substrato comercial esterilizado e mantidas em casa-de-vegetação por cinco meses. A partir dos 61 dias após a semeadura, a altura da muda e o diâmetro do coleto foram mensurados mensalmente. Os isolados CBSAL14 e CBSAL18 promoveram aumento do incremento em altura das plântulas de indivíduos inoculados em relação ao controle, sugerindo seu potencial de uso como promotores do crescimento das plantas.

Abstract: The application of organic composts derived from animal husbandry or agro-industry is a promising option to improve nutrient cycling and supply of soils and, consequently, forage production. The objective of this study was to evaluate the soil chemical properties and the nutritional state of elephant grass in response to rates of organic fertilizer composted from the waste of small ruminant production and slaughter systems. The experiment was conducted on a Fluvisol of a forage field with elephant grass var. Cameroon, and was arranged in a randomized block design with split-plots with repeated measures over time. Six rates of organic compost (0, 13.3, 26.6, 39.9, 52.3, and 79.8 t ha-1, in plots) and an additional treatment with mineral fertilizers were evaluated in four growth periods (60, 120, 180, and 240 days, in subplots) with four replications, resulting in a total of 28 plots. Soil fertility was evaluated after the fourth growth period, while leaf analysis was determined in every 60-day period. The increasing rates of organic compost increased the concentrations of OM, NH4+, NO3?, NH4+ + NO3?, P and base saturation, while the H+Al values decreased and the N and P contents increased in the plants. Compared with mineral fertilization, soil inorganic nitrogen and phosphorus increased by 34 and 97 % in response to the application of organic compost. In response to the application of organic compost, the leaf contents of all studied nutrients remained adequate in all studied periods, except for the macronutrient N and micronutrient Mn.
