Conteúdo: | Changes in tillage practices, especially changes which alter the amount of residue left on the soil surface, often influence soil physical properties wich, in turn, influence soybean (Glycine max L.) growth and yield. However, soybean response to reduced tillage may be positive or negative depending on soil characteristics, previous crop, lenght of growing season, and average rainfall during the growing season. In general, research in North America, South America and Africa has shown that reduced tillage success in favored by soils with good drainage, course texture, and low organic matter, by crop rotation, and at latitudes less tha 40o. Several researchers have classified soils into tillage-management groups. In Indiana, USA, tillage systems ranging from  moldboard plowing to no-till have been assigned success ratings and yield coefficients for several tillage-management soil groups. Within a well defined area, the eastern one-half of the Maize Belt, USA, these ratings show that yield for no-till planting, compared to yield with moldboard plowing, may increase by 10 percent on well drained soils and decrease by 10% on dark, poorly drained soils. Soybean response to reduced tillage should be predictable within an area where soil genesis, latitude and rainfall are similar, where detailed soils information in available, and where long term yield response to reduced tillage is available on a range of benchmark soils.
