The yields from the alternate blocks of section B shown in Table VI 
represent more nearly what may be expected under field conditions. 
The results are similar to those obtained from the alternate rows in 
section A, though the differences are less extreme. The total yields 
_ from the wide-spaced rows ranged from 10.3 to 17 pounds and those 
from the single-stalk rows from 17.2 to 25.2 pounds, the minimum 
yield from the single-stalk rows bemg practically the same as the 
maximum yield from the wide-spaced rows. These results are pre- 
sented graphically in figure 3. At the time the first picking was 
made, August 11, 37 per cent of the crop in the wide-spaced rows was

harvested, as compared with 47 per cent of the crop in the single- 
stalk rows, the latter yielding 93 per cent more seed cotton. The 
second picking from the single-stalk rows was 33.7 per cent greater 
than that from the wide-spaced rows. The increase in the total 
yield of individual rows in any single-stalk block over the correspond- 
ing rows in the preceding wide-spaced block ranged from 15 to 119 
per cent, the average being 56.1 per cent. 
Reference to figure 3 will show that in most cases the inside rows 
of wide-spaced blocks and the outside rows of single-stalk blocks 
yielded more than the other two rows of the same blocks. This
