QUANTIFICATION OF THE VENTILATION OF A GREENHOUSE WITH A ROOF OPENING
(1995)
Measurements of air exchange rates were performed in situ in a glasshouse equipped with a continuous roof opening. These measurements were carried out using the decay rate method with N2O as tracer gas. Simultaneously, ...
OVERALL HEAT-TRANSFER COEFFICIENT OF A GREENHOUSE COVER
(1994)
Theoretical considerations concerning the greenhouse energy behaviour during the night, allow us to propose an evaluation method of the overall heat transfer coefficient through the greenhouse cover material as a function ...
THE SORPTION ISOTHERMS OF POTASSIUM
(1994)
The one- and two-surface Langmuir, the Freundlich and the Temkin isotherms were fitted to potassium sorption data for Alfisol Haploxeralf at pH range of 4.0 to 8.0. Each was found to describe potassium sorption data with ...
Mass selection for improvement of grain yield and protein in a maize population
(1999)
Increasing grain protein concentration in maize (Zea mays L.) has not been a major focus of most breeding programs, which mainly focus on yield, maturity, and resistance to stress. The objective of this study was to evaluate ...
Air flow and associated sensible heat exchanges in a naturally ventilated greenhouse
(1997)
In order to investigate the three-dimensional nature of the air flow within the greenhouse, a three-dimensional sonic anemometer was used for the direct measurement of air and heat exchange inside the greenhouse and through ...
Performance of cotton F-1 hybrids and its relation to the mean yield of advanced bulk generations
(1999)
The performance of intraspecific (Gossypium hirsutum) and interspecific (G. hirsutum x G. barbadense) F-1 cotton hybrids and its correlation with the mean yield of advanced bulk generations was assessed under Greek ...
Evolution of fungicide resistance in Botrytis cinerea in protected crops in Greece
(1997)
Isolates of Botrytis cinerea Pers.: Fr. from different crops and localities in Greece were compared with reference isolates from France and Israel and classified into various groups on the basis of their sensitivity to ...
Isozyme, protein, and RAPD markers within a half-sib family of buffelgrass segregating for apospory
(1996)
Isolation of genes controlling apomixis would be useful to plant breeders for fixing hybrid vigor. A single gene codes for aposporous apomixis in buffelgrass [Pennisetum ciliare (L.) Link]. This study was undertaken to ...
The effect of water vapour adsorption on soil moisture content under Mediterranean climatic conditions
(1998)
The effect of water vapour adsorption on the soil moisture content of different soils under semi-arid climatic conditions (Greece) was evaluated. Time domain reflectometers were used for continuously monitoring soil moisture ...
Wheat establishment after cotton with minimal tillage
(1998)
A method of establishing wheat after cotton by broadcasting the seed without any previous stalk chopping and/or tillage and seed incorporation by a light cultivator was studied under Creek conditions in comparison with ...
