Diurnal variations in leaf – Air temperature and vapor pressure deficit of sunlit and shaded kenaf leaves
(2020)The microclimatic conditions within a crop canopy are differentiated from those outside resulting to the exposure of plant organs in different environmental conditions. In the present study, the diurnal variation of leaf ... -
Effect of two new cover materials on greenhouse energy consumption and cooling load
(2012)The aim of this work was to study the effects of a new polyethylene (PE) film with high reflectance and absorption in near infrared radiation (NIR-PE film) and of a PE film with low transmittance in infrared radiation IR ... -
Effect of vent opening and insect screens on greenhouse microclimate distribution
(2006)The objective of this work was to experimentally investigate the influence of vent type (side, roof or both) and of an anti-aphid insect screen on airflow and temperature distribution of a mono span greenhouse round arch ... -
Experimental results and spatial simulation of climate in a greenhouse with insect screens
(2011)Aim of the present paper was to present, analyze and compare detailed experimental data and CFD simulation results in a greenhouse equipped with insect screens. The studied greenhouse was a round arch type with vertical ... -
Greenhouse cooling by a fog system: Effects on microclimate and on production and quality of a soilless pepper crop
