Six endophytic bacteria of corn roots were identified as Bacillus sp. and as Enterobacter sp, by sequencing of the 16S rRNA gene. Four of the strains, CNPSo 2476, CNPSo 2477, CNPSo 2478 and CNPSo 2480 were positive for the nitrogen fixation ability evaluated through the acetylene reduction assay and amplification of nifH gene. Two Bacillus strains (CNPSo 2477 and CNPSo 2478) showed outstanding skills for the production of IAA, siderophores and lytic enzymes, but were not good candidates as growth promoters, because they reduced seed germination. However, the same strains were antagonists against the pathogenic fungi Fusarium verticillioides, Colletotrichum graminicola, Bipolaris maydis and Cercospora zea-maydis. As an indication of favorable bacterial action, Enterobacter sp. CNPSo 2480 and Bacillus sp. CNPSo 2481 increased the root volume by 44% and 39%, respectively, and the seed germination by 47% and 56%, respectively. Therefore, these two strains are good candidates for future testing as biological inoculants for corn. |

ABSTRACT The use of integrated systems in Brazil started in the beginning of 20th Century. Since then, with the evolution of researches focused on the soil-plant-animal-forest interactions, several integrated systems have been shaped in association to farmers. The main benefits provided by the synergies among crops and pastures are: increase animal productivity by restoring pasture yields, increase crop productivities by improvements in the soil?s physical, chemical and biological properties and the interruption of biotic cycles of weeds, pests and diseases. The main positive impacts on the environment are related to soil and water conservation, increases in soil organic carbon and land-saving effect. From an economic standpoint, mixed systems allow a more rational use of inputs, improvements in cash flow and reduction of the economic risks. The greater nutrients cycling from forages associated to more efficient use of fertilizers by crops saves fertilizers and reduce the production costs. Integrated crop-livestock (ICL) and crop-livestock-forestry systems (ICLF) might be considered as a key strategy to promote sustainable intensification in agriculture. |
