Estimativa da evapotranspiração da cultura de crisântemo em estufa.

Abstract

The aim of this work was to analyze the effect of the plastic covering upon the meteorological elements and estimate the evapotranspiration of crisantemum crop. The results showed that the plastic covering modified the amount of global radiation inside the greenhouse with average values of 63% of the global radiation outside the greenhouse. The estimation of the evapotranspiration using climatic factors measured inside the greenhouse showed better results.
