| ABSTRACT The combination of crop residues or crop extracts is often more advantageous in controlling weeds, than the application of each residue or extract singly. This suggests that in intercropping with maize, the combination of tree species can be more advantageous than species isolated in weed control. The objective of this study was to evaluate the effects of intercropping with a combination of leguminous on the weed growth and corn yield. A randomized-block design with split plots (cultivars in plots) and five replicates was established. The cultivars BR 205 and AG 1041 were subject to the following treatments: two weedings (A), intercropping with sabiá (B), gliricidia (C), gliricidia + sabiá (D) and no weeding (E). In the B and C, 30 viable seeds... |

| ABSTRACT: The objective of the present work was to study the influence of temperature and light on germination of seeds of Stigmaphyllon blanchetii, popularly known as rat tail. The first stage of the research evaluated the effect of three constant temperatures (20 oC, 25 oC and 30 oC) and an alternating temperature (20-30 oC). In the second stage, for simulation of different types of light, four conditions of luminosity (white, red, far red and absence of light) were used. The temperatures that provided the best germination and development for S. blanchetii are the constant (30 oC) and the alternating (20-30 oC) ones. The seeds germinated both in the presence and absence of light, but there was greater germination and seedling development in the absence... |
