Work of 1921. In 1920-21 ninety-six varieties of wheat 

 were again tested by this method. Many of the varieties were the same 

 as those tested in the preceding year, about 20 varieties being eliminated 

 and a corresponding number added. The planting plan was the same 

 as that of the preceding season. Poole wheat was 'used as a check 

 variety. The wheat was drilled at the rate of 5 pecks per acre, October 

 6, in rows running east and west. The season was favorable, but 

 yields were reduced by the very rapid ripening of the wheat caused by 

 the hot dry weather in the second and third weeks of June. The yields 

 are shown in Table 5.
