 ditions for all varieties during an individual test. For this reason 

 results from a series of tests should furnish a more reliable comparison. 

 Table III contains compiled results of twelve varieties which have been 

 tested at the Hunconibe Farm durinir the same five years. The varieties 

 are arranged in order of yield of .shelled corn per acre. The average 

 yields range between 28.5 and 32.1 bushels per acre, a difference of 3.6 

 bushels between the lowest and highest yielding variety. The difference 

 between the highest ;iiid lowest is rather small here, and the differences 

 in the first three or four varieties is too small to be considered of much 

 importance. 



The Iredell Test Farm. 



The Iredell Test Farm is located in the western portion of the Pied- 

 mont section, about two miles northwest of Statesville. This section 

 had unusually good conditions for corn growing during the past season. 

 The rainfall amounted to 59.4, 8.63 inches above normal. About fifty-five 

 per cent of the rainfall came during the growing season. The corn 

 varieties were planted in a uniform field of Cecil Clay Loam. 



The varieties and results of this test are listed in Table IV, accord- 

 ing to yield of shelled corn per acre. 



At the Iredell farm the varieties ranged in yield between 42.6 and 

 60.S bushels per acre, a difierence of 18.2 bushels between the lowest and 

 highest yielding variety. At 75 cents per bushel this gives a difference 

 in money value of $13.65 per acre between the lowest and highest yield- 

 ing variety. The two leading varieties of this test, Jarvis' Golden 

 Prolific and Southern Beauty, are hv.ing bred in the State. Both of 

 these varieties have been good yielders in previous tests at this farm. 



Since twelve of the corn varieties have been tested at the Iredell farm 

 during the same five years a comparison of their average yields should 

 be of value here. Table V contains a list of these varieties arranged 

 in order of their average yields. The average yields range between 

 33.3 and 45.7 bushels ijer acre, with a difference of 12.4 bushels between 

 the lowest and highest yielding variety. In this series of tests the more 

 prolific vareties are the highest yielders. The two varieties which lead 

 in this series of tests do not lead in the production of ears per stalk. 

 Southern Beauty and Weekley's Improved rarely produce more than 

 two ears per stalk. Such results suggest that it would be best to select 

 corn in this section for two medium-sized ears rather than for the larger 

 number of small ears. This matter is discussed more fully in another 

 portion of this Bulletin. 



The Central Farm. 



The Central Farm is located in the eastern portion of the Piedmont 

 section, about two miles west of Kaleigh. The past season in this sec- 

 tion has been unusually dry for the best growth of corn. The total
