IMPORTANCE OF SINGLE-STALK COTTON CULTURE. 
Single-stalk cotton culture was first announced as a new system 
in 1913, and at that time also its principles were outlined. 1 Since 
that year three additional publications 2 have been issued, which 
present results obtained in 1913 and 1914 from experiments with the 
system in Virginia, South Carolina, and Texas. The purpose of this 
report is to present the results obtained in 1915 from a series of 
experiments conducted in the States of Louisiana, Arkansas, and 
North Carolina. 
The single-stalk system is based on the recognition of a fact that 
has not been taken into practical account in most of the cultural
