The objective this research was evaluate the viability corn crop on no tillage over Brachiaria brizantha pasture on the integrated agriculture-pasture system before submeted three soil condioning physical and two cultural sequence. The experiment was carried out at Research and Teaching Farm from UNESP - Ilha Solteira, on red latossol very loamy. The experimental design utilized was a split plot with three main treatments (soil conditioning physical): SM - Non Soil Mobilization; CM - Minimum Tillage; and PC - Conventional Tillage, realized in February/03 being the pasture fenced for re-growth of forage until November/03 when the area was dessecated for the no tillage soybean and corn in December/03. After the hravest these crops the area stayed in rest until August/04 for the re-growth of forage followed animal grazing until September/04 for the implant of the experiment with the no tillage corn over parcels before tilled with soybean and corn established so two different cultural sequence. The yield corn did not influence significantly of treatments utilized showing viable inside the system proposed.
