11.1 ; at 30 inches, 7.9 ; at 36 inches, 4.0; at 40 inches, 4.9 bushels; while 

 at Iredell the increased yields of Cocke's Prolific over Holt's Straw- 

 berry, as an average of the results for 1905, 1906, 1907 and 1908, were: 

 at 20 inches, 7.7; at 24 inches, 4.6; at 30 inches, 6.0; at 36 inches, 7.1; 

 at 40 inches, 6.1 bushels. 



"Weekley's Improved increased yields over Holt's Strawberry, as an 

 average for 1905, 1907 and 1908 at the Edgecombe farm, were : at 20 

 inches, 4.9; at 24 inches, 5.4; at 30 inches, 1.8; at 36 inches, 8.1; at 40 

 inched, 8.4 bushels; while at the Iredell farm, as an average of four 

 years' tests, 1905, 1906, 1907 and 1908, the increases of Weekley's Im- 

 proved over Holt's Strawberry were: at 20 inches, 1.3; at 24 inches, 

 4.1 ; at 30 inches, 7.1 ; at 36 inches, 4.3 ; at 40 inches, 2.2 bushels. 



In the light of these results, coupled with six 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 more prolific varie- 

 ties, 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 produc- 

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



In 1905 Cocke's Prolific and Weekley's Improved, atboth the Edge- 

 combe 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 was 30 

 and 36 inches, respectively. Weekley's Improved, with its best distanc- 

 ing at Edgecombe, yielded 13 bushels more than Holt's Strawberry at 

 40-inch distancing ; while at Iredell Weekley's Improved, with the stalks 

 36 inches in the row, produced 4.2 bushels more per acre than Holt's 

 Strawberry at its optimum distancing (40 inches) in the row. 



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

 the growing period, all three varieties produced largest yields at a dis- 

 tancing 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 outyielded Weekley's Im- 

 proved at both 20 and 30 inches between the hills in four-foot rows. 



In 1907, at the Edgecombe farm, all three varieties attained their 

 highest yields at a distancing of 20 inches in the row. At this distanc- 

 ing Cocke's Prolific slightly exceeded Holt's Strawberry, and Holt's 

 Strawberry exceeded Weekley's Improved by 1.8 bushels shelled corn 

 per acre. At the Iredell farm all three varieties made the best yields 

 at a distancing, of 36 inches in the row. At this distancing Cocke's 

 Prolific exceeded Holt's Strawberry by 4.7, and Weekley's Improved 

 exceeded Holt's Strawberry by 3.1 bushels shelled corn per acre.
