The effect of artificial shading on microclimate conditions in a soybean crop

Abstract

The effect of artificial shading was studied on stomatal resistance and microclimate conditions in a soybean crop (Glycine max (L.) Merrill.). The plastic screen used to regulate the solar radiation level (30%, 50%, 70% and 100% of sunlight) altered the quality of the incident light on soybean plants. White the air temperature and relative humidity were not modifield, the canopy temperature was reduced by shading. Shaded plants showed greater values of stomatal resistance than the plants under full sunlight.
