Growth and development of pistachio seedling root at different levels of soil moisture and compaction in greenhouse conditions
aeration stress bulk density pistachio rooting depth water deficit
2017/4/6
Soil moisture and compaction are important factors for growth and development of plant root. This study was conducted as a nested design with two factors and three replications to investigate the beha...

Microclimate evaluation of a new design of insect-proof screens in a Mediterranean greenhouse
natural ventilation sonic anemometry discharge coefficient ventilation efficiency
2014/10/24
This work studies natural ventilation in a Mediterranean greenhouse, comparing a new experimental screen of 13×30 threads cm-2 (porosity 39.0%) with a commercial control screen of 10×20 threads cm-2 (...
Economics and environmental analysis of Mediterranean greenhouse crops
Toxicity nitrogen water gross margin risk labour
2011/1/13
The aim of this paper is to show that intensive agriculture, as greenhouse crops that produce a high level of environmental pollution, both by nitrogen fertilization as pesticides used, may be distrib...
Preliminary evaluation of the effects of carbonized chicken manure, refuse derived fuel and K fertilizer application on the growth, nodulation, yield, N and P contents of soybean and cowpea in the greenhouse
Carbonization chicken manure grain legumes refuse derived fuel seed yield
2009/3/4
Carbonized organic materials have not traditionally been applied to grain legumes such as soybean (Glycine max L. Merrill) and cowpea (Vigna unguiculata L. Walp) although the potential for favourabl...
Embedded real-time system for climate control in a complex greenhouse
greenhouse climate control embedded real-time systems statecharts integrated development Java
2008/11/19
This paper describes the development of an embedded real-time system devoted to microclimate control in a complex greenhouse. The control system is capable of managing multiple, independent poly-tunne...
Emission of greenhouse gases and soil organic matter balance in different farming systems
organic farming greenhouse gases methane nitrous oxide
2008/11/19
Estimation of the influence of different farming systems on emission of greenhouse gases (methane and nitrous oxide) was the aim of the research. The research was conducted on the basis of a special f...
Temperature and relative humidity changes inside greenhouse
greenhouse temperature humidity data acquisition system

Better growing conditions are achieved in greenhouses by maintaining a higher internal ambient as compared with external ambient temperature. A computer-based control and monitoring system which provi...
Wind-caused air transport through greenhouse screens: a physical modelling approach
air exchange porous screen greenhouse wind pressure physical model
2008/11/10
An understanding of the air exchange through screens is needed to optimise climate control strategies in greenhouses. An analysis of the airflow through porous screens due to wind pressure was perform...
The greenhouse effect and moths’ response to it. I. How to compare climatic and insect phenology databases?
Estonia Lepidoptera distribution of moths climate change
2010/1/12
At present it has been firmly established that climate can be influenced by both natural forces and human activities. It is generally accepted that an increase in greenhouse gas (GHG) concentrations i...
