6 Rows 290.4 feet long by three feet wide making the area of each row exactly one- 
fiftieth acre. Concerning the loss from rot see page 128. 
7It will be observed that Row 3 gave the largest yield of any unsprayed row. This 
is owing to it having been sprayed once by mistake. Hence, incomputing the average 
yields all three rows of Section A should be rejected. 
Comments on the table—(1) In Sections A and C the three- 
sprayed row outyielded the five-sprayed row. The reason for this 
is unknown but it is certainly not due to the spraying. 
_ (2) In every section both of the sprayed rows greatly outyielded 
the unsprayed row. 
(3) In different sections the yields of rows treated in the same 
way varied considerably. This has happened also in all three of the 
previous experiments. It can not be avoided. Confidence is to 
be placed only in averages. | | 
(4) Leaving Section A out of consideration (because of the 
error on Row 3) there were fewer culls on the unsprayed than on 
the sprayed rows. On the unsprayed rows the average yield of 
culls was 30 bu. 25 lbs. per acre while on both of the sprayed 
series the average was 35 bu. 25 lbs. per acre. This is somewhat 
unusual. As a rule there are more culls on the unsprayed rows. 
In the ten-year experiment at Geneva in 1904 there were more than 
twice as many culls on the unsprayed rows as on the sprayed. 
Yield by series—The four rows sprayed three times constitute 
Series I and the average yield of these four rows makes the yield 
ef Series I. The yields given for Series II and III have been com- 
.
