Sorghum [Sorghum bicolor (L.) Moench] is a multipurpose grass cultivated in drylands due to its adaptation to drought. However the characteristics of sorghum-associated bacteria are not known in the Brazilian drylands. The aim of this study was to isolate and evaluate the plant growth promotion potential bacteria from field-grown sorghum under two irrigation and manure application levels in a Brazilian semi-arid reagion. Sorghum was irrigated with 3 or 1 mm day? 1 and fertilized or not with liquid goat manure. Bacteria were obtained from surface-disinfected roots applying two nitrogen-free semi-solid media. The bacteria were evaluated for the presence of nifH gene, 16S rRNA sequences, calcium-phosphate solubilization, production of auxins and siderophores and for sorghum growth promotion. We obtained 20 out of 24 positive bacteria for nifH. The isolates were classified as in six different genera. All isolates produced auxins “in vitro”, six bacteria produced siderophores and three Enterobacteriaceae solubilized calcium-phosphate. At least ten bacteria resulted in the increased total N content in the sorghum shoots, comparable to fertilization with 50 mg N plant?1 week? 1 and to inoculation with Azospirillum brasilense Ab-V5. Enterobacter sp. ESA 57 was the best sorghum plant-growth promoting bacteria isolated in this study. |

ABSTRACT: Stylosanthes guianesis, a Cerrado native species, shows excellent adaptation to this Region, is drought resistance and a ecotype, release as cv. Mineirão, is indicated as protein bank. The Mineirão protein bank has been successfully adopted by farmers to complement cattle diet in cultivated grass pastures during the dry season. This is specially true for Brachiaria brizantha cv. Marandu, the most widespread grass in the Region and which is not suitable for mixing with tropical pasture legumes. Mineirão protein banks can also be an efficient complement for native pastures. Research data and farmer's experiences all over the region supports the use of Mineirão protein bank as an alternative to reduce production costs and increase milk and beef productivity. |
