TABLE PAGE 
1. Relative development of corn plants in the potom- 
eters and in the field 51 
2. Distribution of moisture in potometers with the two 
methods of water addition used in the Nebraska 
experiments 53 
3. Amount of water lost from check potometers in which 
no plants were grown but otherwise treated the 
same as the cropped potometers 53 
4. Effect of size of potometer upon growth and water 
requirements of corn. 1914 58 
5. Effect in per cent of applying manure to potometers 
of different sizes. Results with manure are here 
expressed in per cent of results without manure 61 
6. Effect in per cent of increasing size of potometer 61 
7. Summary showing effect of size of potometer upon 
growth and water requirements of corn. 1914 62 
8. Summary showing effect of size of potometer 
upon growth and water requirements of corn. 1913 .... 63 
9. Effect of degree of exposure of potometer upon growth 
and water requirements of corn 68 
10. Summary of effect of degree of exposure of potometer 
upon growth and water requirements of corn. 1914 .... 69 
11. Summary showing effect of degree of exposure of 
potometers upon their soil temperatures 70 
12. Results from 48 plants grown in potometers in 1912 
to study variation in water requirements 74 
13. Coefficients of variability with dry weight of stalks 
in similar potometers planted with Hogue's Yellow 
Dent corn 77 
14. Coefficients of variability with dry weight of ear in 
similar potometers planted with Hogue's Yellow 
Dent corn 78 
15. Coefficients of variability with dry weight of leaves in 
similar potometers planted with Hogue's Yellow 
Dent corn 79 
16. Coefficients of variability with total dry weight of 
plant in similar potometers planted with Hogue's 
Yellow Dent corn 80 
17. Coefficients of variability with leaf-area per plant in 
similar potometers planted with Hogue's Yellow
