the figures declined on account of the large amount of seed potatoes 

 which had to be deducted. The above figures indicate a very slight 

 advantage in planting halves rather than quarters when the price of 

 seed and crop produced are the same. As a matter of fact, spring 

 prices are usually somewhat higher than fall prices. A high price 

 for seed potatoes may make it profitable to plant smaller pieces ( as, 

 for example, quarters) than would be economical where seed and 

 crop command the same price per bushel. 



Amount of Seed Potatoes. In the following diagram 100 repre- 

 sents the total yield from planting single eyes. The figures may be 

 read as bushels per acre, if it is constantly borne in mind that there 

 are being considered soils of such character as to average 100 bushels 

 of large and small potatoes per acre when planted with 1-eye pieces. 

 The first group answers the question, "What size of seed piece gener- 

 ally affords the largest yield of large and small potatoes?" The 

 second group answers the query : "What size of seed piece generally 

 gives the greatest yield exclusive of small potatoes?" The third 

 group offers an answer to a still more important question: "What 

 size of seed piece generally produces the largest yield after deducting 

 both the small potatoes and the amount of seed planted?" 



Yield from planting different seed pieces, assuming 100 as the total yield from single eyes.
