Fig. 16. — Ears grown in potometers for determining the effect of differences in 
soil moisture content upon growth and water requirements of the corn 
plant. 1913. See Table 54. 
Upper row, seven potometers 50 per cent relative saturation. 
Middle row, eight potometers 70 per cent relative saturation. 
Bottom row, eight potometers 95 per cent relative saturation. 
to represent the soil moisture below optimum. The results of 
this average are practically the same as for the 45 per cent relative 
saturation alone. 
In Table 58, the results obtained under the optimum or inter- 
mediate moisture conditions are regarded as 100 per cent, and 
the results from the other degrees of saturation are expressed in 
percentages of these.
