ASSESSMENT OF A TYPICAL GREEK SHEEP BARN BASED ON POTENTIAL HEAT-STRESS OF DAIRY EWES
(2014)This article studied the potential seasonal heat-stress of dairy ewes housed in a typical naturally ventilated sheep barn located close to the east coast of central Greece. Heat stress was assessed using the Temperature ... -
Calibration and validation of a biological model to simulate the development and production of tomatoes in Mediterranean greenhouses during winter period
(2009)The aim of this work is to calibrate and validate the adaptation of TOMGRO (TOMato GRowth), a crop growth simulation model for tomato, to the short-term cropping technique and to conditions in Greece. Current practice in ... -
Convective and ventilation transfers in greenhouses, Part 1: the greenhouse considered as a perfectly stirred tank
(2002)In this paper, the characterization and modelling of the most relevant convective transfers contributing to the elaboration of the greenhouse climate are reviewed. Convective transfers include heat and mass transfers between ... -
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 ... -
Cultivation of cow cockle (Vaccaria hispanica (Mill.) Rauschert): An industrial-medicinal weed
(2012)Cow cockle (Vaccaria hispanica (Mill.) Rauschert) is an important medicinal weed. Its therapeutic properties are due to present of triterpenoid saponins. Large potential exists to use cow cockle as source of pharmaceutical ... -
Cultivation of milk thistle (Silybum marianum L. Gaertn.), a medicinal weed
(2011)Milk thistle (Silybum marianum L. Gaertn.) is the most researched plant for the treatment of liver disease. Its therapeutic properties are due to the presence of silymarin, a mixture of three flavonolignans (silybin, ... -
Effect of musical stimuli and white noise on rainbow trout (Oncorhynchus mykiss) growth and physiology in recirculating water conditions
(2013)Two musical stimuli transmissions (Mozart and Romanza) as compared with white noise treatment or control, both resulted in significantly higher growth performance in juvenile (6.7 +/- 0.12 g) rainbow trout (Oncorhynchus ... -
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 ... -
Effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity
(2014)The effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity were investigated in a Mediterranean climate (Eastern Greece) under three covering materials (i) a pearl insect-proof ... -
Effects of soil compaction, water and organic matter contents on emergence and initial plant growth of cotton and sugar beet
(1997)The effects of compaction on the emergence and initial growth of cotton and sugar beet plants were studied in pots in a glasshouse experiment. Apart from compaction, the factors studied were two soil types, two initial ... -
Environmental and economic evaluation of N fertilizer rates in a maize crop in Italy: A spatial and temporal analysis using crop models
(2012)Crop simulation models have the potential to assess the risk associated with the selection of a specific N fertilizer rate, by integrating the effects of soil-crop interactions on crop growth under different pedo-climatic ... -
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ... -
Feasibility of a modelling suite for the optimised biomass harvest scheduling
(2010)It has been estimated that 1/3 of forage grass is harvested drier than the optimum moisture content while another 1/3 is harvested while too wet This indicates that dedicated systems supporting decisions that affect grass ... -
Greenhouse evaporative cooling: Measurement and data analysis
(2001)Temperature and humidity gradients were investigated during summer in a commercial greenhouse producing cut roses, equipped with a ventilated cooling-pad system and a half-shaded plastic roof In a steady regime, the cooling ... -
Greenhouse microclimate and soilless pepper crop production and quality as affected by a fog evaporative cooling system
(2007)The influence of greenhouse! humidity control on greenhouse microclimate, crop transpiration rate, and yield and. fruit quality of a soilless grown pepper crop was studied in a greenhouse located at the coastal area of ... -
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 ... -
Harvesting of cotton residue for energy production
(1999)The possibility of collecting cotton stalks in Greece and using them for energy production was investigated. The production and properties of cotton stalks were studied and a system for collection of the aerial part is ... -
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 an insect screen on greenhouse ventilation
(2002)The influence of an insect screen on ventilation rate was experimentally investigated in a multispan glass-covered greenhouse equipped with a continuous roof vent, located at the University of Thessaly near volos in the ... -
Influence of covering material and shading on the spectral distribution of light in greenhouses
(1999)The solar photon flux distribution was measured in the range from 400 to 1100 nm under a twin-span glasshouse and under the same glasshouse with blanked roof, external shading net and internal aluminized shade-screen. ...
