NUMBER OF BOLLS SET. 
To compare the efficiency of single-stalk and wide-spaced rows in 
the production of bolls, the total number of bolls set in rows 3 to 10 
in section A and in rows 58 to 65 in section B were recorded. The 
results of the census are presented in Table IY.

Table IV shows that plants in single-stalk rows set an average of 
five or six bolls each and those in wide-spaced rows about eight bolls, 
but the single-stalk rows contained about 225 per cent more plants 
than the wide-spaced rows, so that the total number of bolls set in 
single-stalk rows was greater. The single-stalk rows in section A set 
149 per cent more bolls than the adjoining wide-spaced rows. In sec- 
tion B the single-stalk rows set 78 per cent more bolls than the wide-
