Convective and ventilation transfers in greenhouses, part 2: Determination of the distributed greenhouse climate
(2002)In this paper, the characterisation and modelling of the most relevant convective transfers contributing to the description of the distributed greenhouse climate are studied in detail. After a brief review of the equations ... -
Effect of different hydropriming times on the quantitative and qualitative characteristics of chickpea (Cicer arietinum L.)
(2011)In dry land areas of the western half of Iran, chickpea due to exposure to rotation with wheat and barley play an important role in maintaining survival of agriculture in these regions. Seed priming is a simple and cheap ... -
Effect of Irrigation Scheduling on Gerbera Flower Yield and Quality
(2010)Better understanding of the effects of irrigation frequency and dose on flower production of gerbera plants (Gerbera jamesonii) can lead to optimal water management and crop yield. Measurements of greenhouse microclimate ... -
Effect of misting on transpiration and conductances of a greenhouse rose canopy
(2001)The influence of greenhouse humidity control on the transpiration rate (lambdaE(c)). sensible heat flux (H-c) and bulk stomatal conductance (g(c)) of a soilless rose canopy (Rosa hybrida. cv. First Red) was studied in a ... -
Effect of Tillage System and Rimsulfuron Application on Weed Flora, Arbuscular Mycorrhizal (AM) Root Colonization and Yield of Maize (Zea mays L.)
(2012)Field experiments were conducted to determine the effects of tillage system and rimsulfuron application on weed flora and growth of maize (Zen mays L. Mitic F1) at a site with no history of pesticide use for the last 5 ... -
Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ... -
Growth and biomass productivity of kenaf (Hibiscus cannabinus, L.) under different agricultural inputs and management practices in central Greece
(2010)The growth and biomass productivity of kenaf (Hibiscus cannabinus, L.) cultivars Tainung 2 and Everglades 41 were determined under three irrigation applications (low: 25%, moderate: 50% and fully: 100% of maximum ... -
THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(2008)The objective of this work was to experimentally investigate the influence of vent type (side, roof, or both) and of anti-aphid insect screens on airflow, air temperature, and air vapor pressure deficit distribution in a ... -
Influence of greenhouse ventilation regime on the microclimate and energy partitioning of a rose canopy during summer conditions
(2001)The influence of the greenhouse ventilation regime (natural or forced ventilation) on the energy partitioning of a well-watered rose canopy (Rosa hybrida, cv. First Red) was investigated during several summer days in warm ... -
Leaf boundary layer conductance in ventilated greenhouses: An experimental approach
(2007)Improving the design, control and management of greenhouse ventilation systems requires a better insight into the coupling and feedback mechanisms between the crop, the internal atmosphere and the outside atmosphere. The ... -
Reducing ventilation requirements in semi-closed greenhouses increases water use efficiency
(2015)We explore an under-appreciated side effect of semi-closed greenhouses: the ability to recover transpired water, thereby increasing water use efficiency. Semi-closed greenhouses are fit with cooling equipment, to limit ... -
Sugar beet genotype response to soil compaction stress
(2000)Eleven sugar beet genotypes were tested for their performance under different soil compaction levels. The genotypes used were three inbreds, three commercial varieties widely cropped in Greece, four experimental hybrid ... -
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ...
