It was found possible to cultivate close to the plants in single-stalk 
rows without injury to the stalks. On the other hand, it was difficult 
to cultivate so close to the plants in wide-spaced rows without injuring 
the vegetative branches and the stalks. 
All fruit was borne on the lower half of the plants in both kinds of 
rows, as may be seen in Plates I, III, IV, and in figure 1 of Plate V. 
As previously stated, the drought caused the shedding of all the bolls 
and flowers that would have developed after July 10. The bare stalks 
that appear above the fruited portions of the plants represent the 
growth made after the middle of July. Until the August rains rcla- 
tively little growth was made, but after these rains the growth was 
very rapid. It was after this period of rapid growth that the taller 
plants in the single-stalk rows began to lean to one side or the other, 
resulting in the form of row shown in Plate I. 
YIELDS FROM SECTIONS A AND B. 
It has been shown that, compared with wide-spaced rows, the 
single-stalk rows in sections A and B showed far less vegetative-branch 
development, and that the plants grew to a greater height, thus 
facilitating cultivation between the rows; they produced flowers in 
ercater abundance, and they set more bolls of about the same size as 
the others, though a higher percentage contained four instead of five 
locks. 
It now remains to be shown how the two systems of culture com- 
pared from the standpoint of yield, which is the most important con- 
sideration, provided that the quality of the lint is not affected. The 
yields are recorded in Table VI. 
Table VI shows that in section A, in which wide-spaced and single- 
stalk rows were compared in alternate rows, the yields from wide- 
spaced rows ranged from 9 to 14.4 pounds, while in single-stalk rows 
the range was from 17.6 to 31 pounds, the lowest yield from the 
single-stalk rows being 22 per cent greater than the highest yield 
from wide-spaced rows. These results are shown graphically in 
figure 2. The increase in the total yield of the single-stalk rows over 
the adjoining wide-spaced rows ranged from 63 to 227 per cent, with 
an average of 125.5 per cent. (See Pl. II.) 
At the time the first picking was made, on August 11, 31 per cent 
of the total crop from the wide-spaced rows was picked, as compared 
with only 26 per cent of the crop from the single-stalk rows. In 
spite of this fact, the first picking from the single-stalk rows yielded 
88 per cent more seed cotton than the wide-spaced rows. The 
second picking was made on September 8, when the yield obtained 
from single-stalk rows was 144 per cent more than that from wide- 
spaced rows.
