This study evaluates the effects of shading nets with photoselective features,
with an open-field control. A green-shade net with a shading intensity of 40%
intensity and blue, pearl, and yellow-shade nets with shading intensity of 75%
were used as netting materials and the total radiation and photosynthetically
active radiation (PAR) transmittance of the shade nets were analysed. The
environmental conditions such as air temperature, relative humidity, and canopy
temperature were measured with the aid of appropriate sensors. Tomatoes were
grown to determine the effects of shade nets on crops cultivated under the four
shade nets, and an additional treatment (control) was used in which tomatoes
were grown under full sun conditions. The vegetative growth parameters, fruit
quality parameters and yields were assessed and the findings showed that
shading resulted in a significant increase in the total yield and pearl-shade nets
are the best choice for producing a high quality tomato crop based on PAR
transmittance (between 44.8% and 52.8%).
