NUMBER OF BOLLS SET. 



To compare me 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 IV.

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-
