In tropical regions the production of ornamentals is developed exclusively in naturally ventilated plastic greenhouses, which sometimes leads to inappropriate microclimates with high temperatures and humidity that limit productive development plants. The aim this work was study air flows, temperature distribution relative inside an alternative greenhouse designed produce rose (Rosa spp.). Three configurations ventilation, side ventilation (SV), roof (RC) combined (RSV) were analyzed....
This work presents a Computer Vision prototype strategy for the automatic detection of mycotic infections on tomato crops. method is based characterization leaflets (both healthy and early blight-infected regions interest - ROIs) by color description (MPEG-7 standard descriptors). A small size ROI collection manually annotated experts used both training testing simple classifier (1-NN). The performance each descriptor under study (Color Structure Descriptor, CSD; Color Layout descriptor,...
The dimensions of a passive greenhouse are one the decisions made by producers or builders based on characteristics available land and economic cost building structure per unit covered area. In few cases, design criteria reviewed established type crop local climate conditions. One that is generally exposed to greater manipulation height above gutter general structure, since with lower has cost. This led some countries in tropical region build greenhouses that, due their architectural...
Tomato represents an important vegetable crop worldwide. During cropping cycle several diseases and abnormal conditions may affect tomato plants resulting on considerable losses of production. A precise identification these pathologies in early phases is fundamental for the implementation control strategies. Nevertheless, right symptoms require highly specialized knowledge facilities, which are not available small growers. Recently, computer vision tools have been proposed as alternative...
The growing expansion of protected horticulture in many regions is occurring around densely populated areas where land for agriculture scarce, expensive or used other purposes. Inexpensive plastic passively ventilated greenhouses are the common choice cultivation these developing regions. objective this work was to analyse effect surrounding constructions and natural obstacles on thermal performance two naturally greenhouses. A saw tooth type greenhouse (TCG), typical Colombian production,...
Abstract In passive plastic greenhouses that do not have heating systems, the phenomenon of thermal inversion occurs, which means temperature inside greenhouse is lower than outdoor environment; therefore, plants are exposed to conditions unsuitable for production. The aim this work was evaluate air climatization alternatives seeking optimize nocturnal microclimate a multi-tunnel Gothic projected rose production in Bogota savannah. experimental approach included use CFD-2D simulation model...
Abstract Carnation production in Colombia, the world’s main exporter, takes place entirely naturally ventilated greenhouses. This type of structure presents non-homogeneous microclimate conditions which differentially affect crop growth and development, is why this issue has been great research interest recent years. The objective was to determine microclimatic behavior a passive spatial-type greenhouse used Colombia for carnation production. experimental approach included collection...
The environmental fate of pesticides has been widely studied in temperate regions but not tropical regions. In Colombia, tomato is an important commodity characterized by the excessive use pesticides; however, yet determined. Residues for 30 were analyzed fruits, leaves, and soils samples, as well residues 490 water sediments, from two open field greenhouse production regions, direct sampling subsequent laboratory analysis through liquid or gas chromatography coupled to mass...
The use of covered structures is an alternative increasingly used by farmers to increase crop yields per unit area compared open field production. In Latin American countries such as Colombia, productive areas are located in with predominantly hillside soil conditions. the last two decades, have introduced cover adapted these conditions, for which behavior factors that directly affect plant growth and development, microclimate, still unknown. Therefore, this research work, a CFD-3D model...
