| dc.description.abstract | The southwestern region of the state of São Paulo, Brazil presents significant area of annual cultures basically composed of cereals under central pivot system irrigation. The bean culture is part of crop rotation used by irrigators from this region, who perform no-tillage management as a form of sustainable soil use. The objective of this work was to compare two soil management systems: conventional management and no-tillage management systems in relation to their effects on the soil physical-hydric properties, compaction and production components of bean culture under central pivot system irrigation. The experiment was conducted at the Buriti-Mirim Farm, Km 223.5 of the Raposo Tavares Highway, Angatuba, SP, Brazil, during the second semester of 2003 using an area irrigated through center pivot system divided into two types of soil managements: conventional management and no-tillage management. Although no-tillage management presented higher water retention capacity at the most superficial soil layers as well as lower compaction, the soil managements did not present significant differences in relation to culture productivity. Since conservationist management cycles are short, it was verified that the no-tillage management practice generated indirect benefits; however, time was not enough to promote structural changes in the soil and hence significant alterations in the physical-hydric properties that would lead to higher root development and culture productivity. | |
