EXERCISE No. 83 



SCORING POTATOES 



i 



Object: To learn whether or not a particular variety of 

 potatoes is profitable from the farmer's standpoint. 



Material: Different varieties of potatoes, such as Early 

 Rose and Rural New Yorker, and a knife. (These samples 

 should be taken from the garden earlier in the fall with notes 

 kept concerning the hills from which they were taken.) 



Method: Score each variety according to the following 

 score card. 



SCORE CARD FOR POTATOES 



I. WILL THEY YIELD WELL? i.e., produce well 



1. Size of Tubers. Individual potatoes should be 

 fairly large, indicating strength and constitution. 



2. Number in the hill. Hills with only a few good 

 sized potatoes are undesirable, also hills with a 

 large number of undersized potatoes. 



3. Compactness in the hill. They should be com- 

 pact enough to gather easily, and spread enough 

 to push out of the ground. 



II. WILL THEY SELL? (Are they what the market 

 demands and are they attractive in appearance?) . . . 



1. Size. Potatoes should be large and of uniform 

 size. 



2. Shape. Tubers should be similar in shape and 

 free from deformities and irregularities.
