Simulação da produtividade de mandioca para o estado do Rio Grande do Sul
(Universidade Federal de Santa Maria, 2013-02-22)
Cassava plays an important role for food security in the tropics, where it is the third main food
source. In Rio Grande do Sul State, Brazil, cassava is a subsistence crop for small farms, who use
cassava for human and ...
Simulação do crescimento, desenvolvimento e produtividade de arroz no Rio Grande do Sul com o modelo simularroz
(Universidade Federal de Santa Maria, 2013-12-19)
The SimulArroz is an ecophysiological dynamic processes-based model for simulating the growth, development and grain yield of rice. In order to have scientific credibility, a simulation model has to be tested and exposed ...
Modelagem matemática do escoamento superficial na escala de encosta sob plantio direto
(Universidade Federal de Santa Maria, 2017-02-24)
The runoff generation over fields with no-tillage agriculture management remains being a problem with environment, social and economic impacts. The purpose of this research was evaluate the capacity of a physic based and ...
Uso de submodelo de competição por plantas daninhas no modelo SimulArroz
(Universidade Federal de Santa Maria, 2018-02-19)
In version 1.1 of SimulArroz there isn’t the option of weed competition. The objective was to introduce in SimulArroz the option of yield loss by weedy rice (Oryza sativa) or barnyard grass (Echinochloa spp.) on irrigated ...
Avaliação do modelo CROPGRO para detectar efeito da compactação do solo no crescimento e na produtividade da soja
(Universidade Federal de Santa Maria, 2020-02-18)
Soil compaction is an inherent phenomenon of the management of large-scale crops and can be
associated to reduction on plant growth and yield. To know the effect of compaction on soil physical
properties is insufficient ...
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 ...
Interferência do intervalo de medição da precipitação na predição da infiltração de água no solo pelos modelos Hydrus- 1D e Green Ampt
