Evapotranspiration in Relation to the Development of the Corn Crop
1959
Denmead, O. T. (Owen T.) | Shaw, R. H.
SynopsisThe corn crop in Iowa approaches the condition of a green crop, actively growing and completely shading the ground for a period of only 2 to 3 weeks during its growing season. In this period the ratio of evapotranspiration to open pan evaporation is 0.81. Before this period the ratio increases with increasing leaf area, and afterwards declines with declining physiological activity of the crop.
