DAWN KAFIR. 
Table VII shows the agronomic data for Dawn kafir in the date- 
of -seeding experiments. The yields are shown also in Table IX and 
graphically in figure 8. 
Good to fair stands were obtained in most plats m all years during 
which the experiments were conducted. In most of the plats the 
row space to the plant ranged from about 5 to 11 inches. A few 
plats had thinner stands, in one the row space being 26 inches to the 
plant. On the average the early seeding gave the thinnest stand 
and the normal seeding the thickest, making a difference of about 3

of Dwarf milo. 
The vegetative period ranged from 71 days for the late date in 
1914 to 118 days for the normal date in 1916. The total growing 
period ranged from 93 days for the normal date in 1917 to 156 days 
for the early date in 1918. The early date usually required a longer 
total growing period than either of the other seedings. This was 
due in part to the slow growth made in the early part of the season 
while the soil temperatures were low and in part to the large number 
of suckers, which are usually later than the main stalk. 
The production of suckers varied greatly in the different seedings 
in the same year and in the same seeding in the different years. In 
1914 the early seeding produced 49.3 per cent of suckers, and the late 
seeding produced only 12.6 per cent. In 1915 a large number of
