Indoor plant cultivation can result in significantly improved resource use efficiency (surface, water, and nutrients) as compared to traditional growing systems, but illumination costs are still high. LEDs (light emitting diodes) gaining attention for indoor because of their ability provide light different spectra. In the spectrum, red blue regions often considered major plants' energy sources photosynthetic CO2 assimilation. This study aims at identifying role played by red:blue (R:B) ratio...
Abstract LED lighting in indoor farming systems allows to modulate the spectrum fit plant needs. Red (R) and blue (B) lights are often used, being highly active for photosynthesis. The effect of R B spectral components on lettuce physiology biochemistry resource use efficiency were studied. Five red:blue (RB) ratios (0.5-1-2-3-4) supplied by a fluorescent control (RB = 1) tested six experiments controlled conditions (PPFD 215 μmol m −2 s −1 , daylength 16 h). increased yield (1.6 folds)...
This study analyzed interactions among photon flux density (PPFD), air temperature, root-zone temperature for growth of lettuce with non-limiting water, nutrient, and CO 2 concentration. We measured parameters in 48 combinations a PPFD 200, 400, 750 μmol m –2 s –1 (16 h daylength), temperatures 20, 24, 28, 32°C. Lettuce ( Lactuca sativa cv . Batavia Othilie) was grown four cycles (29 days after transplanting). Eight low (20 24°C), high (28 32°C) (400 ) resulted an excessive incidence...
Vertical farming (VF) is a type of system where crops are cultivated in enclosed and sunless environments, offering high level precision control the crop environment. Several recent reviews have highlighted VF as potential solution to global challenges like population growth, urbanization climate change, thanks land conservation, sustainability, reduced water usage, enhanced food safety, shorter supply chains. This review critically analyses claims regarding sustainability other proposed...
Models for the evapotranspiration of greenhouse crops are needed both accurate irrigation and simulation or management climate. For this purpose, several models have been developed presented, all based on Penman–Monteith approach, “big-leaf” model. So, one hand, relatively simple scheduling purposes, other, “knowledge–mechanistic” climate control purposes. These differ in amount detail about variables, such as stomatal aerodynamic conductance. The aim review paper is to present variables...
The increase in global food demand has led to the introduction of new production systems. One key example is plant factory. Plant factories face same challenge as many high-tech building functions: high energy demands resulting from internal heat loads. In this study we investigate how can be reduced through façade design. Energy efficient design closely follows function, construction and local climate. Therefore, analysed effects properties on use for three disparate climate zones: Sweden...
Production of vegetables for fresh consumption in arid regions usually takes place greenhouses with evaporative cooling during the warm months year. In this period, water use easily exceeds irrigation use. The purpose paper is to investigate how far can be lowered by adapting design elements greenhouse and system. a trial desert environment, Riyadh (KSA), two different greenhouses: one traditional modified, both equipped pad fan system, have been compared terms productivity main focus on...
Abstract Greenhouse horticulture grows increasingly important due to its ability provide a controlled microclimate which is optimizable for highly efficient crop growth and resource use, although it may come at significant energy investment cost. One of the most crucial inputs in any greenhouse sunlight, giving free light growth. However, enormously variable, both geographically seasonally. This review discusses materials technologies usable cover screen can passively manipulate incident...
Abstract Background Controlled environment agriculture, particularly vertical farms (VF), also called plant factories, is often claimed as a solution for global food security due to its ability produce crops unaffected by weather or pests. In principle, essential macronutrients of the human diet, like protein, could technically be produced in VF. This aspect becomes relevant era protein transition, marked an increasing consumer interest plant‐based and environmental challenges faced...
Greenhouses have been extremely successful in providing abundant, cheap and high-quality produce, by using resources (water, minerals, pesticides) with a very high economic efficiency. Marginal agricultural land is being rapidly converted into protected cultivation many (semi-arid) regions of the world, hoping to pros-per both from primary secondary activities. Water use efficiency greenhouse production about five times as field vegetables. However, spite more efficiently, areas an enormous...
Recent studies concerning the integration of agricultural practices in cities demonstrated that Urban Agriculture (UA) can boost new sustainable urban developments. New technologies allow to integrate soil-less cultivation in- and on- mixed-use buildings, creating synergies between built environment food system. Accordingly, resource flows from buildings are an untapped opportunity for creation circular metabolisms rely on recycling waste as input production systems. On this trail, research...
