1. Implementation of ventilation towers in a greenhouse established in low altitude tropical climate conditions: numerical approach to the behavior of the natural ventilation
ABSTRACT Deficient ventilation rates and airflow patterns in naturally ventilated greenhouses are the main causes for the generation of inadequate and heterogeneous thermal conditions inside this type of structure. In this research, a numerical study was developed using a two-dimensional computational fluid dynamics model validated in a Colombian greenhouse

2. Effectiveness of horizontal air flow fans supporting natural ventilation in a Mediterranean multi-span greenhouse
Natural ventilation is the most important method of climate control in Mediterranean greenhouses. In this study, the microclimate and air flow inside a Mediterranean greenhouse were evaluated by means of sonic anemometry. Experiments were carried out in conditions of moderate wind (≈ 4.0 m s-1), and at low wind speed (≈ 1.8 m s-1) the natural ventilation

3. Aclimatação de mudas micropropagadas de bananeira (Musa spp.) cv. Grande Naine / Acclimatization on microprpgated banana plants (Musa spp.) cv. Grande Naine
passar por um período de aclimatação, pois não realizam eficientemente a absorção de luz, água e nutrientes. A aclimatação deve ser feita em casas de vegetação, onde as condições de umidade relativa do ar e luminosidade são favoráveis a um endurecimento gradual das plântulas, período este que, para bananeira, se divide em dois estágios: o p

4. Influence of systems of handling in the production and in the reservations of precocious peach tree (Prunus pérsica (L.) Batsch.) cultivated in tropical climate. / Influência de sistemas de manejo na produção e nas reservas de pessegueiro precoce (Prunus pérsica (L.) Batsch.) cultivado em clima tropical.
The precocity maturation is the main factor of economical success of the producing of peach from São Paulo, in view of that fact the very big demand exists goes new techniques that make possible the improvement of the quality of the fruits and the larger precocity in the crop. This work seeks to verify the influence of the systems of prunings and maintenanc

5. Nitrogen fertilization effects and phosphorus sources in sabiá (Mimosa caesalpiniaefolia Benth.), subjected to hydric stress. / Efeitos da adubação nitrogenada e fontes de fósforo em sabiá (Mimosa caesalpiniaefolia Benth.), submetido ao estresse hídrico.
Due to the social accountability demanded from university research, this study is related to the challenge of making available development strategies for regionssuch as the semi-arid northeastern regions, which is characterized mainly by its limited soil and climate conditions. The purpose of this work was to assess the behavior of sabiá seedlings (Mimosa c
