suckers and that the high percentage of suckering is not due entirely 
to thin stands. 
In height the range has been from 3.S to 6.5 feet in the different 
years. The height and its variations are not significant, the variation 
in average height for the 5-year period being onlv that between 5.3 and 
5.8 feet. 
The yields of grain obtained are more consistent for Sunrise kafir 
than for Dwarf Yellow milo. During the five years, the May 15 
seeding has produced the highest yields in three years and in a fourth 
year, 1921, it made but 0.5 bushel less than the June 1 seeding, which 
was the highest yielder. In two of the five yea rs the June 1 seeding 
yielded highest. 
From these facts it 
appears that the 
best date for seeding 
Sunrise kafir under 
conditions similar to 
those at the Wood- 
ward Field Station 
is from May 15 to 
25. The period dur- 
ing which Sunrise 
kafir may be seeded 
to make the best 
returns probably ex- 
tends from about 
May 5 to 25. 
As kafir is better 
than milo for forage, 
the yields of the 
total crop are also of 
importance. The 
May 15 seeding ex- 
ceeded any other seeding by almost half a ton to the acre, the average 
total production from this seeding being 6,109 pounds per acre. The 
June 1 seeding ranked next, followed by the May 1 and June 15 
seedings. The June 15 plats of Dwarf Yellow milo in the same five 
years produced an average total crop of 6,599 pounds.

DAWN KAFIR. 
Date-of-seeding experiments have been conducted with Dawn kafir 
since 1919. The agronomic data for this variety for the three years 
are presented in Table IS. The annual and average grain yields are 
shown for comparison with other varieties in Table 21. 
Dawn kafir was not seeded on April 15 in these experiments, as it 
had been proved from the test with Sunrise kafir that April 15 is too 
early to sow kafir and obtain fair stands. In 1920 a plat of Dawn 
kafir was seeded on July 1. but from this one seeding and from the 
"results obtained from the July 1 sowing of Sunrise kafir it was 
apparent that July 1 is too late to seed kafir and expect a well- 
ma tured grain crop. As the April 15 sowing was not included in the 
experiment with Dawn kafir, the stands obtained on the Dawn kafir 
plats were very uniform and were comparable between years and 
between different dates in the same year.
