CEEEAL EXPERIMENTS AT DICKINSON, N. DAK. 



25 



XL During four years of this period, 1909, 1911, 1912, and 1913, 

 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 oats 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 1910 

 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.
