Foi conduzido um experimento em casa de vegetação, onde foram estudados os efeitos de N sobre o crescimento e absorção de nutrientes pelo sorgo granífero. As plantas foram cultivadas em solução nutritiva completa ou com nitrogênio diluída a 1/2, 1/5 e 1/10 da concentração usual, e foram colhidas aos 110 dias da emergência, quando foram separadas em raiz, colmo, folhas, raquis e grãos. O material foi secado, moido e foram feitas análises de nitrogênio, fósforo e potássio. Os resultados obtidos permitiram concluir que os níveis de nitrogênio utilizados tiveram efeitos nas produções de matéria seca das plantas, assim como nas quantidades de nitrogênio, fósforo e potássio absorvidas. As cultivares apresertaram reações diferentes aos níveis de nitrogênio.

This study discuss the use of the geotechnologies to aid the planners on the terrain aptness definition for highways implantation and on the different trace evaluation to the extention of the Governador Carvalho Pinto highway, between Taubaté-SP and Aparecida do Norte-SP. Fratures on the area were mapping using Landsat ETM+, band Pan. In order to elaborate the phisical aptness chart for highway implantation was used the Analitical Hierarchy Process (AHP) operation, in on geographical information system (GIS). Using GIS were realized a ponderate middle with the soils, rocks, relief, slope, fractures and land use/cover maps. Using this physical aptness chart and joinning it with urban and restrict areas (that was inserted by the Boolean operation), were obtained a viability chart for highway implantation. Based on it were proposed three aleatory traces for the Carvalho Pinto highway. This traces were evaluated with the cross tabulation operation. The integration of the restrict areas, land use and phisical aptness in digital media can offer for the planners the cartography of the viability for the highway implantation. The evaliation of these three traces, based on the viability chart, can subsidyse the decision by the planners.

The highways are enterprises of great longitudinal extension that cross several types of lands, that possess different geologic, geomorphologic, pedologic and vegetation conditions. In the environmental management of highways the importance of the use of Engineering Geological Maps of Susceptibility was noticed, for being documents that inter-relates several information of the environment. This way, this research objectified the elaboration of this type of map and the indication of lines of direction for the conservation of the Highway Marechal Rondon - SP-300. For its elaboration the Map of Declivity, the delimited Homogeneous Physiographic Units, the processes of the superficial dynamics mapped and the use of the ground was used. Its elaboration evidenced its importance for the environmental management of highways, in view of the prevention, the monitoring and the correction of the adverse processes that can occur in this type of enterprise.
