THE SEED.

ments comparing the results from seed from 

 different parts of the ear.* In these experi- 

 ments, extending from 1882 to 1885, the results 

 slightly favored the tip kernels. The follow- 

 ing table gives the results: 



YIELD PER ACKE IN BUSHELS. 



At the Ohio experiment station the average 

 yields per acre for four years were, butt, 66.9; 

 central, 62.8, and tip 64.8 bu. per acre.f 



At the Kansas station the relative productive- 

 ness was first from tip, second from butt and 

 third from central kernels.^ 



There is not sufficient evidence at hand to 

 justify the rejection of either butt or tip ker- 

 nels, provided they are of good vitality, in 

 favor of the kernels from the center of the ear. 



The size of the seed planted, on the basis of 

 the evidence given above, would not seem to 

 play any special part in productiveness of crop. 

 If the size did affect the yield we should expfect
