SILVEIRA, Gastão Moraes da et al. Tillage management practices in soybean wheat double cropping. Bragantia [online]. 1984, vol.43, n.2, pp.493-507. ISSN 1678-4499.  https://doi.org/10.1590/S0006-87051984000200020.

In a field experiment set up in Assis county, State of São Paulo, Brazil, two seeding processes namely no-till and conventional tillage systems for soybean (Glycine max (L.) Merrill) and wheat (Triticum aestivum L.) (double cropping) were studied. Special emphasis was given to the different seeding machines. Three crop yields were obtained. For wheat the treatments were: conventional seeding (heavy disking and leveling disking) and no-till. For soybean we had: conventional seeding plus chiseling; conventional seeding; plowing and disking; plowing and disking plus scarifying and no-till. The results showed that the interaction among the treatments were not significant, and that the soil management for soybean did not affect the wheat production. Fuel saving was significant for both crops in the no-till system. Machine articulation was essential to fit the roughness of soil surface in no-till.
