Modelagem da evapotranspiração e produção para Alstroemeria x Hybrida irrigada em ambiente protegido
(Universidade Federal de Santa Maria, 2019-08-05)
Modeling of crop productivity, when inserted in the ornamental sector, is not widespread. There are few specific models for estimating ornamental crop production due to the requirement of calibrated parameters for the ...
Fragilidade ambiental da Bacia do Arroio Guarda Mor
(Universidade Federal de Santa Maria, 2020-07-23)
Erosion hotspots act as sediment sources and are responsible for the transfer of sediments, nutrients and pollutants, leading to soil and water degradation. The erosive process occurs on variable and continuous range of ...

Simulação do rendimento de grão de arroz irrigado em cenários de mudança climática
(Universidade Federal de Santa Maria, 2010-02-18)
Climate change projections indicate that current atmospheric CO2 concentrations (380 ppmv) will double by the end of this century, which may lead to an increase in crop yield due to an increase in photosynthesis. However, ...
Efeito da competição no incremento em área transversal de Araucaria angustifolia (Bertol.) Kuntze em floresta ombrófila mista, no Sul do Brasil
(Universidade Federal de Santa Maria, 2018-02-19)
The competition is considered the most important factor on growing trees in a forest. Hence, we aim to describe asymmetric competition and annual periodic increment in cross-sectional areas of trees of Araucaria angustifolia ...

Biomassa para fins energéticos em área de regeneração natural de Ateleia glazioviana Baill
(Universidade Federal de Santa Maria, 2017-07-27)
This study aimed to evaluate the biomass for energy purposes in the natural regeneration area of Ateleia glazioviana Baill. For this, allometric models of volumetry were tested and determined to the energy properties of ...
Simanihot: um modelo de simulação da cultura da mandioca e sua aplicação em clima futuro no Rio Grande do Sul
(Universidade Federal de Santa Maria, 2016-03-01)
Crop models are tools that can help to assist in decision making on crops management and also in studies of the impact of future climate scenarios. The objectives of this thesis were (i) to develop a cassava simulation ...
Validação de simulação para cenário futuro da microrregião da campanha ocidental, RS, Brasil
(Universidade Federal de Santa Maria, 2018-02-26)
Dynamic landscape modeling has been used to simulate scenarios, quantifying and tracking changes in use and land cover through time. Based on these simulations, scenarios have been constructed projecting conversions into ...
