Resumen:
In modern agriculture, the soy has place of prominence, guaranteed for the high
productivity and excellent yield in the market, mainly in the exportation of grains. But a good productivity
and consequent yield an adequate planning of the production must be had, with techniques of adequate
preparation of the ground to each region of the country. For such, one developed this work in the
Universidade Estadual Paulista, Faculdade de Ciências Agrárias e Veterinárias, Campus de Jaboticabal,
SP, with the objective to analyze the effect of different soil tillage in the soybean crop (Glycine max (L.)
Merrill) in a Oxisoil, being they conventional (disc plow + two soft harrowings, moldboard plow and two
soft harrowings, heavy disc harrow + soft harrowing), 2 reduced (chiselplow + softharrowing, chiselplow
only) and no tillage, resulting in 6 treatments with 4 repetitions. The water text in the ground it did not
have significant differences between the treatments. In the superficial layer (0-5 cm) the no tillage
presented greater resistance to the penetration in relation to the treatments mondboard plough and two
harrowings and chiselplow and harrow. The agronomical characteristics of the soybean crop had not been
influenced by the studied treatments.
