ripe. To the novice, when a field of corn is fully tasseled, 

 it has about completed its growth, but the following table shows 

 in a most effective manner that great changes are still going on 

 within the stalks and that the storage of nutrients has only fairly 

 begun: 



Water and dry matter in corn crop at different periods after tasseling 

 New York (Geneva} Station. 



The table shows that an acre of corn when fully tasseled 

 weighed nine tons, more than eight of which were water. The 

 water in the corn continued to increase in total amount until 

 August 21, at which time the kernels had reached the full milk 

 stage, after which it decreased. The total dry matter increased 

 from the beginning. Between the milk and glazing stages there 

 was the remarkable increase of over a ton of dry matter per acre 

 of crop in seventeen days. From glazing to full ripeness there 

 was a further increase of dry matter, though it was small.

 age of nutrients in the crop at different periods to be as given 

 below:
