In Table XIII are shown the average dates of heading and maturity, 

 weight per bushel, and yields of grain and straw of two strains of 

 Kharkof and one of Turkey wheat grown on the Belle Fourche 

 Experiment Farm from 1908 to 1917, inclusive. The yields also are 

 shown graphically in figure 6. It is seen that the dates of heading

and maturity and the height are the same for all three wheats and 

 that the differences in weight per bushel and yield are too small to be 

 significant. From the results obtained it is concluded that the bulk 

 unselected varieties, Turkey and Kharkof, are identical in all the 

 above characters, including yield. These varieties, however, have 

 outyielded.all others grown in the plat and nursery experiments.
