New Improved SEMESAN JR. 
To make sure New Improved Semesan Jr. is adapted to 
your needs, we have tested it for three years under all sorts 
of conditions. Fifty-one farm tests in 20 Corn Belt counties 
have been conducted on fertile soils and poor soils; on 
heavy soils and light, sandy soils; with tested seed and 
non-tested seed; in good seed beds and poorly prepared, 
cloddy seed beds. 
One to Six Extra Bushels per Acre 
We can’t begin to give you in this booklet the results of 
all these tests, but the table below contains a fair sample. 
These are the figures for all tests completed on 14 Iowa 
and Illinois farms in 1933. The yields from seed treated 
with New Improved Semesan Jr. are compared with the 
yields from the same seed untreated and planted under 
identical, actual farm conditions. The treated seed out- 
yielded the untreated seed in every case by 134 1° 634 
bushels per acre. The average increase in yield was over 
33^ bushels per acre or about 8%.
