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
