16 BULLETIN 526, U. S. DEPARTMENT OE AGRICULTURE. 



Table X shows a wide variation in yields from the two systems of 

 culture. In the yields from the first picking, single-stalk culture led 

 in 4 of the 10 instances. In 3 instances the yields were identical and 

 in 3 other instances greater yields were obtained from the old-method 

 rows. The total yield from the first picking was slightly (3 per cent) 

 in favor of single-stalk culture. 



In the yields from the second picking, single-stalk culture led in 

 only 3 of the 10 instances, while the old method led in 4. In 3 in- 

 stances the yields were identical. It is remarkable that the yields 

 throughout differed in about the same proportion. The total yield 

 of the second picking, however, favored the old method of culture 

 by 20 per cent, making an increase of 8 per cent in total yield for this 



method. 



Arkansas. 



Owing to the damage done by early spring floods, most of the experi- 

 ments begun in Arkansas were abandoned. The only ones which 

 promised any dependable results were located in Miller County, in 

 the vicinity of Texarkana, and at Warren, in Bradley County. The 

 latter experiment, however, was located in a pecan grove and the 

 trees apparently so reduced the supply of moisture in the soil that 

 when the drought of August was encountered the cotton plants were 

 compelled to shed a large proportion of their squares. This damage, 

 combined with apparent weevil damage, made the test practically 

 without value. 



MILLER COUNTY. 



The experiments in Miller County were conducted by Messrs. D. R. 

 Akin, J. E. Tanner, and W. B. Latta, the first named being located 

 about 10 miles south of Texarkana, at Fouke, and the others being 

 located in the immediate vicinity of Texarkana. Mr. R. M. Meade, 

 of the Bureau of Plant Industry, visited these experimenters early in 

 June and directed the thinning of the single-stalk rows. 



The Akin experiment. — Mr. D. R. Akin, of Fouke, planted Lone Star 

 cotton on May 20, about 15 days later than usual. Unfortunately, 

 only a small amount (12 pounds per acre) of seed was planted, and 

 a relatively poor stand resulted. Wet weather occurred immediately 

 after planting, and this was followed by drought, which caused the 

 surface soil to bake. At the time of thinning the single-stalk rows 

 it was observed that the plants were not standing thick enough to 

 insure complete suppression of the vegetative branches, but enough 

 had been suppressed to make the test worth carrying out. 



There were 28 rows in the experiment, 8 in which the two systems 

 of culture were compared in alternate rows and 20 in which com- 

 parisons were made in alternate blocks of 5 rows each. The plants 

 in the old-method rows were spaced about 18 inches apart and those 

 in the single-stalk rows about 8 inches, wherever the stand per-
