Entre febrero de 1990 y marzo de 1994, en un Ultisol de la hacienda experimental Santa Rita, de la Empresa de Pesquisa Agropecuaria de Minas Gerais, Brasil, a 19o 28' de latitud sur 45o 15' de longitud oeste, a 732 m.s.n.m., 1418 mm y 21 C, con vegetacion caracteristica de Cerradao, se realizaron dos experimentos para medir la adaptacion y produccion de MS de seis gramines (B.brizantha BRA 003247, 003441, 003484, 003891, 000591 cv. Marandu y B. decumbens BRA 0049912) y nueve leguminosas forrajeras (Stylosanthes guianensis BRA 008150, 003671 cv. Bandeirante, 017817 cv. Mineirao, 1536 IPF EPAMIG, Centrosema brasilianum BRA 012297, Centrosema hibrido 040231, C. acutifolium 006483 e 009181 y 0066025). La produccion de MS se evaluo a las 3, 6, 9 y 12 semanas siguientes al corte de uniformizacion, tanto en el periodo de maxima como de minima precipitacion. Despues de 3 anos de evaluacion se observo que las accesiones B. brizantha BRA 003441 y 003484 fueron las mas resistentes al ataque de salivazo (Deois flavopicta y Mahanerva fimbriolata) y no se encontraron diferencias en produccion de MS entre las accesiones evaluadas. En las leguminosas, la produccion de MS de las accesiones de Centrosema fue inferior a la de las accesiones de Stylosanthes, siendo S. guianensis BRA 008150 la que presento la mayor produccion en el terce ano de evaluacion. |

Soil salinization is a significant abiotic factor threatening agricultural production, while the low availability of phosphorus (P) in plants is another worldwide limitation. Approximately 95-99% of the P in soil is unavailable to plants. Phosphate-solubilizing bacteria (PSB) transform insoluble phosphates into soluble forms that plants can utilize. The application of PSB can replace or partially reduce the use of P fertilizers. Therefore, selecting bacteria with high solubilization capacity from extreme environments, such as saline soils, becomes crucial. This study aimed to identify twenty-nine bacterial strains from the rhizosphere of Salicornia fruticosa by sequencing the 16S rDNA gene, evaluate their development in increasing concentrations of NaCl, classify them according to their salinity response, and determine their P solubilization capability. The bacteria were cultivated in nutrient agar medium with NaCl concentrations ranging from 0.5% to 30%. The phosphate solubilization capacity of the bacteria was evaluated in angar and broth National Botanical Research Institute (NBRIP) media supplemented with calcium phosphate (CaHPO4) and aluminum phosphate (AlPO4), and increased with 3% NaCl. All bacterial strains were classified as halotolerant and identified to the genera Bacillus, Enterobacter, Halomonas, Kushneria, Oceanobacillus, Pantoea, Pseudomonas, and Staphylococcus, with only one isolate was not identified. The isolates with the highest ability to solubilize phosphorus from CaHPO4 in the liquid medium were Kushneria sp. (SS102) and Enterobacter sp. (SS186), with 989.53 and 956.37 mg center dot Kg(-1) P content and final pH of 4.1 and 3.9, respectively. For the solubilization of AlPO4, the most effective isolates were Bacillus sp. (SS89) and Oceanobacillus sp. (SS94), which raised soluble P by 61.10 and 45.82 mg center dot Kg(-1) and final pH of 2.9 and 3.6, respectively. These bacteria demonstrated promising results in in vitro P solubilization and can present potential for the development of bioinput. Further analyses, involving different phosphate sources and the composition of produced organic acids, will be conducted to contribute to a comprehensive understanding of their applications in sustainable agriculture MenosSoil salinization is a significant abiotic factor threatening agricultural production, while the low availability of phosphorus (P) in plants is another worldwide limitation.
