TABLE NO. 26 

 ♦SHOWING RELATION OF GERMINATION TEST TO STAND IN THE FIELD 



AND YIELD 



The above table shows conclusively that the germination test 

 properly conducted is a safe indication of the power of the seed to 

 produce in the field. 



Another test including 4000 individual ears tested and planted as 

 in the above experiment, serves further to prove the relation between 

 the germination, stand in the field and actual yield. 



TABLE NO. 27 

 ♦SHOWING VALUE OF INDIVIDUAL EAR TEST 



The above test covers five years, 109 experiments in twenty-seven 

 counties. 



The value of the germination test has been already emphasized, 

 but further data relating to the relation of stand in the field to actual 

 yield is given in the following table : 



TABLE NO. 28 

 ♦SHOWING RELATION OF STAND TO YIELD. (Result of eight years test in Iowa) 



It is of special significance to note that in the above tests only 28.2 

 per cent of the seed actually planted by the 4776 farmers represented, 

 gave a stand of 80 per cent or better. The average stand of all tests 

 being only 71.7 per cent. 



While definite data could not be secured from all states, a poor 

 stand of corn in the field is given universally as the greatest cause of a 

 low average yield, and the germination test has been everywhere 

 urged as the only practical means of detecting and eliminating the 

 weak and dead unproductive seed ears.
