desired stands in all rates. The row space to the plant for the differ- 
ent rates is shown in Table X. 
The average stalk space varies much less in the different rates 
than the plant space, because of the difference in the number of 
suckers produced per plant in the different rates. The percentage 
of suckers varies in the different rates in the same year and in the 
same rates in the different years. In general, however, the per- 
centage of suckers increases as the stand decreases. The thick rate 
produced 5,8 per cent of suckers in 1918, which was the minimum 
in the 6-year period. The maximum, 74.4 per cent, was produced

l^y the thin rate in 1914. It appears that from 65 to 75 per cent, or 
an average of about three suckers to the plant, is the limit for Dwarf 
milo and that such rates of suckering may be expected under favor- 
able conditions from plants with 10 to 20 or more inches of row 
space. 
The percentage of erect heads was high in most years, reaching 
almost 100 per cent in all rates. Thin stands have a greater tendency 
to produce pendent heads than thick ones, but growing conditions 
at the time the crop is heading probably are the determining factors 
in their production. Rapid growth at heading time is favorable to 
the production of pendent heads. 
The yields of the total crop and those of grain in pounds and in 
tushels of 58 pounds each are recorded in Table X. The thicker
