11)18.] DEMONSTRATION- IN (OUN JL'lJ(';iNG. 47 



Too iiiciny people take tlie corn -^.-re card at its fa*. : vaiiLc, 

 looking no furtlier than the scmic card for a desirable sample 

 of corn. A corn score card does not tell us anything about 

 the yield which will be obtained if the corn is j)lanted. A 

 number of men have been experimenting with corn along the 

 line of the score card to see if the dilTerent ear marks have 

 anything to do ^\•ith the yield of ct)rn. 1 mean by that, does 

 the length of the ear or the filling (jut at the tip. the circum- 

 ference, the space between the kernels, the smallness of the 

 butt, etc., ha\e anything to do with the yield?' These men 

 who have been experimenting are tinding out some imjxjrtant 

 things about the present score card, and Professor Williams, 

 whc^ was to have been here this afternoon, has summarized 

 some of these points : 



First: He tested long ears as compared with short ears 

 and found that the average yield for long ears was 1.39 

 bushels per acre over short ears. There is thus very little 

 difiference in yield when long ears, as compared with short 

 ■ears, are planted. 



Second : Tapering ears yielded 1.65 bushels better to the 

 acre in the dent than in the flint. There is very little differ- 

 ence between yields of the cylindrical and tapering ears. 

 Flint corn fills out better at the top than dent corn. 



Third : In a seven-year average bare tipped ears gave a 

 better yield than well tipped ears, .3-1 of a bushel to the acre. 



Fourth : He experimented with ears of corn having a 

 high shelling-out percentage against a low shelling-out i)er- 

 centage. Seed ears having 88% corn on the cob averaged 

 ■64.6 bushels per acre as against 65.06 bushels to the acre of 

 shell corn for ears having only T6% of grain on cob. This 

 proves that corn which doesn't shell out the most gives about 

 as good yield as that which has the highest shelling per- 

 centage. The ideal ear is not always a better yielder in the 

 field than the ear which is not ideal. 



I miofht cite other instances to sh«^w that the ideal ear as 

 outlined by the corn score card need not necessarily be the 

 best ear of corn for seed. The best corn score card is one 

 which would give us an idea of the yield of the corn if 

 planted. 



I do not wish to throw cold water on the corn judging
