A. aEstrategias de cultivo de milho (Zea mays) sobre cobertura permanente de Arachis pintoi. c1998 aThe effect of several intensities of soil preparation and herbicide application on the biomass of Arachis pintoi BRA-031134 and on weed incidence in maize (Zea mays) established in a 3-yr-old A. pintoi crop was determined in a red-yellow Latosol in Uberlandia (Minas Gerais, Brazil). Treatments consisted of soil preparation with a subsoiler, two passes of plow-rake, and use of disc plow plus one pass with a soil grader. Glyphosate (1.08 kg/ha + 1% urea) was previously applied to A. pintoi vegetation, 2 weeks before maize planting. Plots prepared using the subsoiler and plow also received an application of 20 g/ha of chlorimuron to control A. pintoi regrowth. Results indicated that herbicide application was suffcient to temporarily control A. pintoi (10.9 t/ha in the check versus 0.6 t/ha with the herbicide) during maize establishment by direct seeding. Good results were also obtained using a subsoiler without herbicide application. aArachis pintoi abiomass aherbicides aweeds aBiomassa aCerrado aHerbicida aMilho aZea Mays aMaize aPlanta daninha1 aVILELA, L.1 aPIZARRO, E.
