Resumo: | The allelopathic effect studied in many cultures has currently generated great expectations that displayed a natural and environmentally friendly tool for weed management using bioherbicides. The objective of this work was to assess allelopathic influence of residues of S. trilobata on the germination and growth of weeds, as well as their relation with some crops and effects on soil properties. Results show that residues from S. trilobata have inhibited the germination of weeds (31.6 - 72%), increasingly with the applied dose. All residue doses of this specie have inhibited dicotyledonous germination, but only maximum concentration has affected monocotyledons. The residues did not affect onion germination, but stimulated it in radish and tomato, while the dose applied at 50% produced tomato stimulation and inhibition of cabbage. The effects of residues on hypocotyl growth in different crops showed changes in species response. For onion, the three doses had negative effects on the growth of hypocotyl, while tomato was stimulated. For radish, the growth was hindered by any dose applied, and were only different (50 and 100%) compared to control. For cabbage, only hypocotyl length was stimulated, when maximum dose (100%) was applied. For the radicle growth, in onion and radish no differences were found compared to control. While the tomato radicle growth was inhibited, in cabbage, all doses encouraged the elongation of the radicle. The dry mass of weed was affected by increased dose of residue (0.49 - 8.8 g m-2), however the soil microflora was stimulated, while the population of Azotobacter spp. was not affect. Some soil properties were affected, the level of organic material, Na+ and electrical conductivity were increased, while pH (H2O) decreased a bit, however it remained basic. |
