CEREAL EXPERIMENTS AT DICKINSON, N. DAK. 25 
XI. During four years of this period, 1909, 1911, 1912, and 1918, 
computed yields were figured from the use of check plats. These 
computed yields are given in Table XII, with average actual yields 
for comparison. 
The cats were sown in 1907, 1908, and 1909 on new land that 
had been broken the previous season and before seeding had been 
worked down well with the disk and spike-tooth harrows. In 191uU 
and succeeding years this crop was sown on spring-disked land on 
which corn had been grown the preceding year. The seed was sown 
about April 20 except in 1912, when seeding was delayed till May 
7. The usual rate of seeding has been 6 pecks to the acre. The 
worked down well with the disk and spike-tooth harrows. In 1910 
the later varieties were destroyed by hail. On July 11, 1912, the 
oats were severely injured by hail, but all varieties produced good 
yields of seed from the second growth except the White Russian, 
which did not mature.
