Abstract
Four 0.1 ha glasshouses were erected at Efford Experimental Horticulture Station, Hants, to compare yield from a range of crops and measure transmission of solar radiation.
A multispan structure with East-West orientation gave a higher solar-radiation measurement and produced tomatoes with a better total-yield than an identical structure orientated North-South and two wide, clearspan structures.
One of the single widespan structures was of conventional design with a 26° pitched roof and the other designed with a mansard-shaped roof.
The solar radiation transmission was higher in the two widespan structures around the winter solstice and earlier-maturing lettuce were harvested in these houses at this time compared with the multispan structures.
There was no significant difference between the two widespan structures.
