COMMENTS ON DISTANCE TESTS OF COTTON. 



The average results of the distance tests conducted at the Edge- 

 combe and Red Springs farms during the past four years indicate 

 that the best distancing of cotton for the Edgecombe section is some- 

 where about 314 feet by 16 inches, while at Red Springs it centers 

 closely around 4 feet by 16 inches. As the average of four years' 

 tests at the Iredell farm the best distancing was 3 1-3 feet by 16 inches. 



At the Experiment Station farm, as an average of five years' re- 

 sults, a distancing of 39.6 inches between the rows with the plants 

 12 inches in the row has afforded the largest yield of seed cotton per 

 acre. The next best -average is from a distancing of 39.6 inches by 

 16 inches, but this was, on an average, 67.8 pounds of seed cotton 

 less than 39.6 inches by 12 inches. 



The general deductions above should be accepted tentatively, as 

 here, as with other tests, it will require a number of repetitions to 

 arrive at a fair idea of the best width of rows and distance in rows 

 for planting cotton on the types of soils on which these tests were 

 made. 



The plats at the four farms were arranged in lateral series, with 

 each test occupying from three to five rows. 



As the results of this test are likely to vary somewhat with differ- 

 ent varieties, Culpepper's Improved seed were used at Red Springs 

 and Experiment Station, Russell's Big Boll at Edgecombe, and 

 King's Improved^ at Iredell, 



^ Culpepper's Improved was used in the test of 1903.
