Aiming to evaluate the effects of soil management and cover crops on microbial indicators of soil quality, an experiment was carried out under field conditions in which common bean and corn were cropped under no-tillage (NT) and conventional tillage (CT) after sunnhemp, velvet bean, pigeon pea, jack bean, sorghum and fallow (weeds). The basal soil respiration (BSR), C and N of the microbial biomass (Cmic and Nmic), metabolic quotient (qCO2), total enzymatic activity (TEA), ?-glycosidase (?-GA) activity and acid phosphatase activity (APA) were evaluated in samples collected in 0-0.10 m depth. Cmic, qCO2, TEA, ?-GA and APA were more sensitive in determining the effects caused by tillage and cover crops. Although the cover crops had not provided a remarkably influence on the studied indicators, in general, the highest values of Cmic, Nmic, BSR, TEA, ?-GA and APA and the lowest values of qCO2 were observed under NT compared to CT. Cmic and TEA values were 35% and 13% higher under NT when compared to CT, respectively. In addition, NT showed values closer to those found under "Cerrado" area for the studied parameters, indicating a greater sustainability under this soil management system compared to CT management. |

In the present study, the objective was to analyze the molecular response mechanisms to drought through the expression of the DREB1 and HDZ7 genes, along with the analysis of physiological and biochemical parameters, in the BRS Morena sesame cultivar inoculated with plant growth-promoting rhizobacteria and drought tolerance-promoting rhizobacteria. |
