ABSTRACTCultivating maize under systems of alley cropping results in improvements to the soil, a reduction in weeds and an increase in yield. Studies using ground cover from tree shoots produce similar results. The aim of this study was to evaluate the effects on weed growth and maize yield of ground cover made up of 30 t ha-1 (fresh matter) of branches from the tree species: neem (Azadirachta indica A. Juss), gliricidia [Gliricidia sepium(Jacq.) Kunth ex Walp.], leucaena [Leucaena leucocephala (Lam.) de Wit.] and sabiá (Mimosa caesalpiniifolia Benth.). Two treatment groups (cultivars and weed control) were evaluated. The cultivars AG 1041 and AL Bandeirantes were subjected to the following treatments: no hoeing, double hoeing, and ground a cover of... |

ABSTRACT Mulching using crop residue reduces the growth of weeds and increases the yield of various crops. The aim of the present study was to evaluate the effects of Gliricidia sepium branches, used as mulch, on weed control, and on grain yield in corn. A randomized block design was used, with split plots and five replications. The cultivars, 30F35H and AG 1051, were grown in the plots, and the following treatments applied in the subplots: no weeding, two weedings, and mulching with 10, 20 or 30 t ha-1 (fresh weight) gliricidia branches. The mulch material was applied between the sowing furrows after sowing the corn. Increasing the amount of gliricidia branches caused a linear reduction in weed growth, and increased growth and yield in the corn. Weed... |
