middle, in the forward left portion of the second triangle, and 
- at the forward left apex of the third triangle. On this root- 
yield diagram the low region occupies the whole right margin 
of the lowest triangle and a portion of the same margin of | 
the second triangle. Just one set of proportions (T2R2S3) is | 
set down as in the low group on both diagrams. | 
It is especially interesting to note that the yields of tops and 
of roots agree very well, a feature of these results that is dif- ; 
ferent from what has been indicated for wheat and buckwheat : 
by Shive’s work; that writer frequently found low root yields 7
