Resumo
The research aimed to evaluate soil properties and performance of crops in two soil management systems in a Humic Cambisol in southern Brazil. The treatments were no tillage (NT) and conventional tillage (CT) during the crops of corn (Zea mays), beans (Phaseolus vulgaris) and soy (Glycine max) in two growing seasons. The experimental design was a randomized block with four replications in a factorial split plot. Soil samples were collected at three depths at the end of the second crop, while vegetable production evalua- tions were performed at the end of each crop. The type of vegetable specie not influenced the soil proper- ties, whereas the effect of soil management systems was evident. The NT is greater contents in soil of Ca, Mg, P and K, while the CT is grater macropore volume at the soil surface. Differences in crop performance occurred in the second year, finding in NT largest grain yield in soy and corn and higher thousand-grain weight in beans, compared to CT. Beans and soy produce low dry mass of shoots, independent of the management system, while corn produces higher amount and higher in NT.
