Golden Rain has given the highest average yields. The Victory 

 oat has yielded next in order. 



The average length of time from planting to maturity varies from 

 103 days for the Kherson and Sixt}^-Day varieties of oats to 128 days 

 for the White Russian. The average date of heading for the varie- 

 ties is July 11 and the average date of ripening August 13. 



The average yield of all varieties of barley for the seven years 

 from 1907 to 1913 was 30.3 bushels. 



Two pedigreed 2-rowed varieties of barley, Hannchen and Svan- 

 hals, have proved best adapted to the conditions at Dickinson. These 

 varieties have outyielded the commonly grown 6-rowed varieties, 

 Manchuria and Oderbrucker, from 36 to 55 per cent during the years 

 grown. The naked varieties of barley have produced comparatively 

 small yields each year at Dickinson, averaging about the same as 

 the Manchuria. 



The Yaroslav emmer has given a higher average acre yield of 

 grain for the five years 1907 to 1911 and 1913 than Early Mountain 

 oats, Hanna barley, or Kubanka wheat. 



The cereal nursery has afforded an opportunity for growing a 

 larger number of varieties and selections than could be included in 

 field plats. The tests in the nursery are confined to short rows. Here 

 new varieties are compared with standard and better known sorts. 

 A large number of pure-line selections from several unpedigreed 

 varieties which have proved well adapted at Dickinson are being 

 tested in the nursery. Considerable crossing has been done in an 

 attempt to originate new and better varieties. Most of the crosses 

 have been made with winter wheat, with the object of increasing 

 their winter resistance.
