58 CORN AND GRAIN JUDGING 



apt to be of too great depth to mature well in northern 

 climates. Immature and chaffy corn gives a relatively low 

 percentage of grain to cob compared with well-ripened corn. 

 When judging corn for percentage of grain to cob, weigh 

 five ears of the sample and record the total weight. Then 



Fig. 31. Proportion of cob to grain. The cobs and grain of the two ears at the right 

 are shown at the left. The shorter ear with thicker cob had more grain than the 

 long ear with the slender cob. The percentage of grain to cob cannot be judged 

 accurately with the eye, and the grain should be shelled off and both cob and grain 

 weighed to determine this point. 



shell and weigh the grain and record the weight. Divide 

 the number representing the weight of the shelled grain 

 by the number representing the weight of the ears and the 

 result will be the percentage of shelled corn. 



GENERAL CUTS 



Directions for Judging. A defect may be so serious 

 that it should cut down the sample as a whole over and 

 above the cuts given on the ears. An ear in a sample of
