The vegetative period for the milos has varied from 72 days in the 
years 1914. 1916, and 1921 to 107 days in 1917, the average duration 
of the vegetative period being 82 days. The long vegetative period 
in 1917 was due to the drought of June and July, which occurred 
before the milos had headed, followed by late rains which caused 
second growth. The ripening period of milos has varied from 30 and 
31 days in various years to 43 days in 1917, with an average of 36 
days for the 8-year period. The length of the total growing period has 
been from 102 days in 1914 to 150 days in 1917, averaging 118 days 
for the 8 years. The variations in duration of vegetative, ripening, 
and total growing periods can be accounted for by a study of the 
climatic conditions, especially precipitation, obtaining during the 
growing seasons. 
Tne average row space intended for each plant of milo in these 
experiments was about 7 inches. The variation from this spacing 
has been considerable at times, but the averages have not been far 
from the spacing desired. By a study of Table 6 it may be seen that 
the stands have been fairly comparable between varieties in any year; 
also between those of the different years. 
The average stalk space has varied with the season and with the 
varieties, it being dependent on the plant space and extent of sucker- 
ing. The average for the eight years has been 6.6 inches for the 
Standard Yellow milo, 6.4 inches for the Standard White milo, and 
5.6 inches for the two selections of Dwarf Yellow milo. The extent of
