in the row thinned to one plant every 12 inches was 104 as compared 
with a mean of 270 for thé hills with several stalks. Therefore, instead 
of three stalks to the hill, an average of only 2.7 stalks was obtained. 
(Table 16.) In 14 out of the 15 comparisons, yields of the two inside 
rows of the blocks with three plants in hills 12 inches apart gave the 
higher yields. The single comparison in which 3 plants in hills 12 
inches apart did not produce more cotton than the wider spacing was 
where the yield of both spacings was the same. 
TaBLE 16.—Comparative yields in cotton-spacing experiment with three plants in 
hills 12 inches apart and single plants 12 inches apart, Greenville, Tex., 1925 
[The rows, which were 100 feet long, were planted Apr. 13 and thinned June 1 (when the plants were 
about 5% inches high and were bearing about seven true leaves). The first picking was Sept. 4 
and the second one Oct. 17]

Comparing the yields from the two inside rows of each block of 
the different spacings, there is a mean difference of 1.126+0.130 
pounds in favor of the spacing with three plants in hills 12 inches
