At tlie Edgceoiiibo fanu in 11)05 Cocke's Prolific produced the fol- 

 lowing increase of bushels of shelled corn over Holt's Strawberry: 

 At 20 inches, 9.G ; at 24 inches, 12.1 ; at 30 inches, 14.0 ; at 36 inches, 

 3.9; at 40 inches, 4.0 bushels; while at Iredell the increased yields 

 as an average of the results of 1905 and 1906 were 10.4, 3.7, 4.4, 

 6.9, and 3.8 bushels per acre at the respective distances. 



Weekley's improved increased yields over Holt's Strawberry were : 

 At Edgecombe in 1905 10.8 bushels at 20 inches, 9.2 at 24 inches, 

 16.4 at 30 inches, 15.6 at 36 inches, and 9.0 at 40 inches; while at 

 Iredell as an average of two years the increases were 1.7, 4.0, 3.2, 

 5.4, and 1.1 bushels. 



In the light of these results, coupled with five years' variety tests, 

 it is evident that the largest yields of shelled corn per acre on any 

 type of soil are going to result generally from the use of the more pro- 

 lific varieties, because they will produce more shelled corn per stalk, 

 and, as the stalks are generally smaller and can be planted closer in 

 the row, will contain more stalks per •acre. 



When the corn is planted wide apart in the row and in wide-apart 

 rows — matters not if the best one-eared varieties are used — the land 

 will not "turn out" the maximum yield which it is capable of pro- 

 ducing, for the reason that there are not enough stalks per acre. . 



In 1905 Cocke's Prolific and Weekley's Improved, at both the 

 Edgecombe and Iredell farms, produced their largest yields in these 

 tests at the distancing centering about 30 to 36 inches, while Holt's 

 Strawberry did best at the greatest distancing. At the most favorable 

 distancing (40 inches) Holt's Strawberry at the Edgecombe and 

 Iredell farms yielded less by 12.6 and 4.2 bushels of shelled corn 

 per acre, respectively, than Cocke's Prolific at the distancing best 

 suited to it, which were 30 and 36 inches, respectively. Weekley's 

 Improved, with its best distancing at Edgecombe, yielded 13 bushels 

 more than Holt's Strawberry at 40-inch distancing; while at Ire- 

 dell Weekley's Improved, with the stalks 36 inches in the row, pro- 

 duced 4.2 bushels more per acre than Holt's Strawberry at its opti- 

 mum distancing (40 inches) in the row. 



In 1906, being a year in which excessive amounts of rain fell dur- 

 ing the growing period, all three varieties produced largest yields at 

 a distancing of 20 inches in the row ; while the next best yields for 

 all were at 30 inches in the row. This year seemed to be especially 

 favorable to the. production of maximum yields of all the large one- 

 eared varieties, and at the Iredell farm Holt's Strawberry out- 

 yielded Weekley's Improved at both 20 and 30 inches between the 

 hills in four-foot rows.
