The Bulletin. 25 



All of the above tests were made in the coastal plains section and 

 on soils of the JSTorfolk series with the exception of that made at Til- 

 lery. Here the soil was a rather heavy silt loam soil found in the 

 ancient flood plains of the Eoanoke River. 



There were a number of tests made in the piedmont section. Table 

 Xo. YI shows the results of the work at Salisbury in Rowan County. 

 Here the best yielders were Excelsior Prolific, Simpkins', and Lewis 

 Long Staple, while the lowest yielders were Rosser No. 1, Allen's Multi- 

 plier, and Culpepper's Improved. 



In Rutherford County, Morgan's Climax, Webber, and Thigpen's 

 Prolific made the highest yields as shown in Table J^o. VII, while 

 Summerour, Cook's Improved, and Simpkins' made the lowest records. 



At the Iredell Test Farm, Summerour, Lewis Long Staple and Cul- 

 pepper's Improved made the best record as shown in Table 'No. VIII; 

 while the lowest yields were made by Allen's Multiplier, Hawkins', and 

 Shine's Early. 



Attention should be called to the unusually high per cent of lint 

 made by some of these varieties during 1911. Those that made an 

 unusually high per cent of lint were :

Tables IX and X show the compiled results of variety tests that have 

 been in progress at the Edgecombe and Iredell Test Farms during 

 several years past. While a great many varieties have been tested, 

 a number of them were for one reason or another, in the tests of only 

 one or two years, and it was not thought proper to admit them to the 

 compiled tables. 



The last columns of these tables show the average yield in seed cotton 

 during the years tested. 'No variety was admitted to the tables that 

 was not tested as many as three years. 



THE BEST VARIETY. 



In case you have been careful in the selection and adaptation of your 

 seed, we unhesitatingly say the best variety for you to use is the one 

 you have developed on your own farm. By adaptation we mean the 

 growing of the same variety on the same kind of land for a sufficient 

 length of time to allow it to become adjusted to its soil and climate 

 surroundings.
