ABSTRACT
The most comprehensive study of the relationship between plant growth and transpiration is that carried out by L. J. Briggs and H. L. Shantz at the U.S. Department of Agriculture field station at Akron, Colorado, from 1910 to 1919 and completely summarized by Shantz and Piemeisel. 1 Their data and those of others revealed that under conditions of relatively high soil fertility and constant climate, the yield of above-ground dry matter obtained from a particular kind of plant is directly proportional to the amount of water transpired. The relationship under a specific set of conditions is thus Y = k 1 Tr https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781351072878/38527347-c5ad-4144-b03a-1c6a17eaf960/content/unequ15_1.tif"/>
