Effects of a UV-absorbing greenhouse covering film on tomato yield and quality
(2012)The effect of blocking the ultraviolet (UV) solar radiation using a UV-absorbing low density polyethylene (PE) film on tomato crop yield and fruit quality was evaluated in a two-year study in two arched roof greenhouses ... -
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 ... -
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 ... -
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 ... -
A simple model for ventilation rate determination in screenhouses
(2015)The objective of this work was to study and model the ventilation rate in screenhouses. Thus, microclimate variables and crop transpiration as well as the air velocity were measured in three screenhouses covered by different ...
