| The sunflower (Helianthus annus L.) represents an important alternative crop for rotation programs, because sunflower can be cultivated at different times of the year. The objective of this work was to select sunflower cultivars adapted to production in Taubaté-SP. Experimental data from 2000 to 2001 evaluated the performance of four cultivars: Cargill 11, CATISSOL, RUMBOSSOL-90 e MORGAN 734 in a randomized complete blocks design, with five blocks and plots consisting of six lines of 5.0 m each, distanciated 0.80 m; the distance between plants inside the row was 0,25 m. The cultivars RUMBOSSOL-90 and MORGAN 734 were the most productive for cultivation in Taubaté-SP off-season |

| Due to fast urbanization and the access and traffic facilities, many cities had been constructed close the great highways, where soils next to these highways are subject to many potential pollution sources, mainly the emissions from discharge for automotive vehicles. Concentrations of lead and zinc had been determined in soils and plants samples within 50 m of the edges from Presidente Dutra highway, in the valley of the Paraíba do Sul River, in the southeastern region of Brazil. The results had shown that the biggest concentrations of these metals find at 0-10 m of distance from the highway edges and decrease with increasing distance from highway. The average Pb and Zn concentrations in the study areas, respectively, were: 34,9 e 189,6 ppm (0-10 m); 10,6... |
