GRAIN SORGHUMS IN THE TEXAS PANHANDLE. 
31 
These data are shown in Tables XV to XIX, 
need to be considered, 
inclusive. 
FIRST SECTION, J{OWS 3^- F12ET APART. 
Table XV shows the results with Dawn kafir in the spacing experi- 
ment with the rows 3^ feet apart. (Fig. 10.) Six plats were sown 
each year, representing six different rates. In a few cases practically 
the same stands were obtained in two plats in the same year. This 
condition occurred in the first two plats in 1914 and again in the last 
two plats in 1918. In general the thick rate ranged from 3 to 7 inches 
and the thin rate from 15 to 20 inches of row space to the plant in the 
different years. However, the last two plats in 1917 and in 1919 had 
much thinner stands.

The tendency to produce suckers changed with the stand and with
