GRAIN-SORGHUM EXPERIMENTS IN OKLAHOMA. 
47 
From a comparison of the number of stalks per plant it is apparent 
that Sunrise kafir has a tendency to produce more suckers than Dawn 
kafir under all conditions which existed during the three years from 
1919 to 1921 and for the dates when both Dawn and Sunrise kafirs 
were seeded.

kafirs at the Woodward Field Station for the years 1919, 1920, and 1921.

1 The July 1 see ling of Dawn kafir in 1920 was not ripe when harvested. 
2 Some stalks of the Apr. 30 seeding produced more than one head. 
During the three years when date-"of-seeding plats of both Dawn 
and Sunrise kafir were grown the ratio of height of Dawn to Sunrise 
kafir was 1 to 1.40 in 1919, 1 to 1.44 in 1920, and 1 to 1.45 in 1921, or 
an average for the three years of 1 to 1.43. The total growing periods 
have been the same for Dawn and Sunrise kafir. 
From the results for the three years it appears that Dawn kafir 
makes its highest average yield when seeded on May 15, with the 
June 1 sowing second highest. Sunrise kafir has consistently made 
yields of total crop higher than Dawn. 
REED KAFIR. 
Reed kafir (C. I. No. 628) was included in the date-of-seeding 
experiments in 1921. Results for a single year are not of much 
value, but the data are presented in Table 18 to show the behavior 
of this variety. This kafir produced fewer sucker- and slightly 
higher grain yields than either Sunrise or Dawn kafirs when sown on
