Soil—Plant Relationships in Soybean Cultivated under Conventional Tillage and Long-Term No-Tillage

Soybeans [Glycine max (L.) Merrill] have great economic prominence in the world, and soil management systems can directly interfere with their yield through changes physical-hydric properties. Thus, aim of this research was to verify relationship between components, physiological traits, root development, properties soybean yields grown under conventional tillage no-tillage systems. The experiment carried out Botucatu, SP, Brazil, two treatments: soybeans no tillage. It is a long-term experiment, conducted since 1986. main variables that influenced were plant height, relative leaf water content, dry matter, penetration resistance, accumulated infiltration. Physiological components showed significant negative correlation yield. On other hand, development physical positively correlated However, not significant. system resulted 7.8% more productivity compared Soybean depends on storage capacity soil, as well traits plant.
