early stage to the ]iots with only 0.5 gm. of nitrogen. Excessively high nitro- 

 gen fertilization with continued droughts reduced the 1,000-kernel weight. 



By grouping the haulms and heads witli reference to fertilization and the 

 amount of water supplied the author obtained quite regularly graded series of 

 data on length, weight, fruitfuluess of head, and 1,000-keruel weight. The 

 regularity of this gradation was also maintained in case of the number of 

 kernels per head when much water was supplied during the first vegetation 

 period.
