1. SHADING LEVELS AND PLANT GROWTH REGULATOR FOR FORMATION OF SCHIZOLOBIUM AMAZONICUM COMPACT SEEDLINGS
ABSTRACT Paricá (Schizolobium amazonicum) can be used for rehabilitation of degraded lands, timber manufacturing markets. However, for its planting, high-quality seedlings should be used. Thus, this study aimed to evaluate the effect of different types of paclobutrazol (PBZ) application and two shading levels on high-quality seedling production. As there wa

2. Interspecific Competition Between Sweet Sorghum and Weeds
RESUMO: Enquanto evidências indicam o sorgo sacarino [Sorghum bicolor (L.) Moench] como uma matéria-prima de etanol alternativa durante a entressafra da cana-de-açúcar (Saccharum officinarum L.), pouco se sabe sobre sua capacidade produtiva em condições adversas (sob competição com plantas daninhas, por exemplo). Portanto, o objetivo do presente estu

3. Rotational grazing of native pasturelands in the Pantanal: an effective conservation tool.
Deforestation and conversion of native habitats to exotic pasture and crops, plus inefficient agricultural and cattle management practices, are placing great pressures on natural resources in the Pantanal and Cerrado. To prevent further deforestation and protect biodiversity, areas already developed for farming and ranching need to be managed more efficientl

4. Morfología forestal y confort térmico en "ciudades oasis" de zonas áridas
Usually, cities settled in arid or semi-arid regions follow an urban development model based on compact morphologies as a bioclimatic strategy for the control of solar radiation. However, the reference case in this study, the city of Mendoza, Argentina, located also in a seismic and semiarid zone, has a different urban model. The city displays wide road chan

6. Characterization and use of diazotrophic bacteria isolated from different rice cultivars originated from Maranhão State. / Caracterização e uso de bactérias diazotróficas isoladas de diferentes cultivares de arroz originárias do estado do Maranhão.
Several works have shown that rice crop can benefit from the association with diazotrophic bacteria. However, the biological nitrogen fixation (BNF) in rice is dependent of a complex interaction among the plants, microorganisms and the ecosystem. The general objective of this work was to evaluate the contribution of BNF in varieties of rice originated from t

10. Edaphic attributes in cultivated pasture areas in the northwest of the State of Rio de Janeiro / Atributos sedáficos em áreas de pastagem plantada em relevo movimentado no noroeste do Rio de Janeiro
One of the largest challenges of the world agriculture is to increase the productivity of several crops, to obtain larger return on the investments, with sustainability. For that, it is necessary to study how to minimize negative effects of agricultural handling and alterations in the soil functional and structural properties, and the behavior of the system
