Resumo: | In Brazil, the upland rice culture system is predominant, but its water supply depends of precipitation and its distribution. Some practices or disturbances on soil conditions may cause alterations that can be detected by microorganisms, which are quite sensitive. This experiment was developed to study microbiological alterations (microbial biomass carbon (MBC), released CO2 (C-CO2), metabolic quotient (qCO2) and mycorrhization), as well as alterations in soil fertility and productivity of upland rice, cultivated under different soil and water managements. Cultivar BRS Talento was used in the experiment. The experimental design was a completely randomized block design, with four replications, using three soil managements: no-tillage (NT), heavy disk + leveling disk harrowing (HL), and chisel plowing + leveling disk harrowing (CL), plus three water managements: no irrigation (WD0); water depth 1 (WD1), with irrigation at the reproductive and maturation periods; and water depth 2 (WD2), with irrigation throughout the rice cycle. Autochthones arbuscular mycorrhizal fungi proved to be sensitive to soil and water management. The NT presented the highest values for MO, Ca, SB and V% and the lowest for H+Al. This management, together with irrigation at the reproductive and maturation periods of BRS Talento cultivar, promoted goods results for crop yield and microbiology characteristics |

Determinadas práticas ou distúrbios, que atuam sobre o solo, levam a alterações que os microrganismos, por ser sensíveis, podem detectar. O trabalho objetivou estudar as alterações microbiológicas (carbono da biomassa microbiana (CBM)) e do CO2 (C-CO2) liberado, do quociente metabólico (qCO2) e micorrização), fertilidade do solo e produtividade do arroz de terras altas, cultivado sob diferentes manejos de solo e água. A cultivar utilizada foi a BRS Talento, e o delineamento experimental foi o de blocos casualizados, com quatro repetições. Os tratamentos foram arranjados em fatorial de três manejos de solo: plantio direto (PD), grade pesada + grade niveladora (GG), escarificador + grade niveladora (EG) e três manejos de água: sem irrigação (L0); lâmina 1 (L1), que corresponde à irrigação nas fases reprodutiva e de maturação; e lâmina 2 (L2), que corresponde à irrigação durante todo ciclo. Os fungos micorrízicos arbusculares mostram-se sensíveis aos manejos de solo e água. O PD apresentou as maiores médias para MO, Ca, SB e V% e as menores de H + Al. Este manejo acrescido da irrigação, apenas nas fases reprodutiva e de maturação propiciaram resultados satisfatórios para a produtividade e características microbiológicasUniversidade Estadual de Maringá2008-04-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/178810.4025/actasciagron.v30i2.1788Acta Scientiarum.
