The annual yields of each variety for each date of seeding are 
given first, followed in each case by the 6-year average. Dwarf 
mile made its highest yield, 70.3 bushels, from the normal seeding 
in 1915, and the lowest yield, 2.9 bushels, from the early seeding in 
1918. The normal seeding in this variety yielded highest in five 
years, and was exceeded by the early seeding in one year. The late 
seeding made better yields than the early seeding in four of the six 
years. In average yield during this 6-year period the normal seed- 
ing ranks first, with 30.2 bushels, the late seeding takes second place, 
with an average of 26.6 bushels, and the early seeding is third, with 
an average of 25.2 bushels. This tends to show that the normal 
date, from about May 20 to 25, is the best time to sow Dwarf milo 
in that locality, and that it is safer to delay seeding a little than to 
sow much earlier than the dates -mentioned.

The lowest yield of feterita was produced from the early seeding 
in all six years. The normal seeding made the best yields in two 
years and the late seeding in four years. On the average the late 
seeding takes first place with 26.8 bushels, the normal is second 
with 21.9 bushels, and the early comes last with only 15.2 bushels. 
The yield from the late seeding on the average is more than 5 bush- 
els larger than that of the normal and over 1 1 bushels more than from 
the early seeding. This shows clearly that early seeding should not 
be practiced with feterita in the Amarillo section. 
Dawn kafir made the highest yields from the early seeding in three 
years and a failure in one year. The normal seeding ranked first 
in one year and the late seeding ranked first in two years. In the 
6-year average the early seeding ranks first with 22.2 bushels, the
