Water and fertilizers use efficiency in grafted and non grafted tomato plants on soilless culture
(2008)
The improved rooting environment and the absence of pathogens in substrates used in soilless cultures, make the use of grafted plants unnecessary when grown hydroponically. The worldwide water shortages and the increased ...
Computational fluid dynamics applications to improve crop production systems
(2013)
Computational fluid dynamics (CFD), numerical analysis and simulation tools of fluid flow processes have emerged from the development stage and become nowadays a robust design tool. It is widely used to study various ...
Transpiration and energy balance of a greenhouse rose crop in mediterranean summer conditions
(2001)
The transpiration rate of a soilless rose crop and its interactions with the greenhouse microclimate and energy balance were investigated during summer conditions in Greece. At this aim, measurements of transpiration (γE ...
Greenhouse evaporative cooling: Measurement and data analysis
(2000)
Temperature and humidity gradients were investigated during summer in a rose production greenhouse equipped with a ventilated cooling-pad system and a half shaded plastic roof. In a steady regime, the cooling process reached ...
Use of a decision support system for management of the drainage solution in semi-closed hydroponic systems under different drainage fractions
(2014)
Soilless cultivation, especially in closed-loop hydroponic systems offers a great option for water saving in greenhouses. Capture and recycling of the excess irrigation water that drains out of the root zone is possible ...
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Development and evaluation of a DSS for drainage management in semi-closed hydroponic systems
(2014)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Daily temperature optimisation in greenhouse by reinforcement learning
(2005)
The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously ...
Effects of anti-drip cover materials on microclimate and production of a hydroponic cucumber crop
(2008)
Recent year's concerns about food safety, environmental pollution, worker's safety, resistance to chemicals and the need for rational use of energy stimulated extensive research concerning the development of alternative ...
Influence of aluminized thermal screens on greenhouse microclimate and night transpiration
(2003)
The aim of this work was to characterize the influence of a thermal screen on: the greenhouse microclimate, energy savings and crop transpiration. Measurements were carried out during winter in a glasshouse cultivated with ...
