Fig. 23. 



In selecting seed corn ears Nos. 2 and 3 should be discarded as no planter 

 will drop a uniform number of these kernels per hill. 



Ears Nos. 1 and 4 have kernels of uniform size and shape and when the 

 butts and tips. were shelled ofif the planter dropped three kernels to a hill 93 

 to 95 times out of every hundred tests while ear No. 2 tested 74-3's, 19-2 's, 

 6-1's and 1-5. 



SPACE BETWEEN ROWS. 



Fig. 24. Ear No. 3 has about the right amount of space between the rows 

 to insure best results, while ears 1 and 4 illustrate the extremes. Ear No. 1 

 has too much space showing a deteriorated or ''run-out" appearance, and 

 shelling oat a low per cent of corn to cob. On the other hand where there is too 

 little space between the rows, as in the case of No. 4, the ear generally 

 presents a dull, starchy or immature appearance. The kernels are too 

 pointed or wedge-shaped, leaving a great deal of open space next to the cob, 

 and are lacking in vitality. Ear No. 2 has a little too much space, while 

 ^here is perhaps not quite enough on ear No. 5.
