Abstract

Sweet pepper (Capsicum annuum L.) is one of the main cultivated vegetable species in Hungary mostly produced under plastic tunnel by unheated technology.
Sweet pepper plants can suffer from high temperature and radiation during the summer season.
However, photoselective-shading nets can provide a new tool for radiation quality manipulation and support the plant development and fruit quality.
The effect of shading of coloured nets depends on solar radiation conditions and on other environmental factors.
A sweet pepper variety was grown in South-East Hungary under plastic tunnels using different coloured nets, such as white, yellow, green and red nets during summer 2013. Results of the trial have proved that green coloured net usually decreased the yield, while yellow and red nets can increase the yield and the fruit quality.
Growers have to consider the shading intensity of the net, which should not be higher than 35-40%. Coloured shading nets can be placed onto the plastic tunnels just after the planting.
