ABSTRACT The objective of this study was to evaluate the weed management in maize using hoeing and intercropping with Mimosa caesalpiniifolia ('sabiá'). A randomized block design that consisted of split plots and five replicates was used. The hybrids AG1051 and BR205 (plots) received the following treatments: A = hoeing [20 and 40 days after sowing the maize (DASM) and without intercropping]; B = hoeing 20 DASM followed by the planting of 'sabiá'; C = planting of 'sabiá' at the time the maize was sown followed by hoeing 40 DASM; D = planting of 'sabiá' at the time the maize was sown; and E = no hoeing and without intercropping. Lesser weed growth in the plots of two hybrids was observed with the treatments that involved hoeing. The highest yields for maize were obtained with two hoeings. The combinations of hoeing and intercropping provided higher grain yield compared to only intercropping with sabiá. Grain yield with hoeing 20 DASM and intercropping with sabiá was higher compared to intercropping with sabiá and hoeing 40 DASM.
