“The ee of foliage indicated that great benefit could be 
derived from the ploughing up, but these plats were planted too 
late for any benefit to be derived from the practice of ploughing 
up, as the plants checked by it at first, although recovered 
sufficiently to make the greater growth above ground, had not time 
thereafter to make a corresponding growth of tubers. Had the 
crop been planted and ploughed up to earlier, there would in all 
probability have been an opposite result in the amount of crop © 
produced. 
AFTER EFFECT OF FERTILIZERS IN FIELD G— 1889. 
One-twentieth acre plats were measured off, one on each of the 
fertilizer plats for grass in 1888, to which no fertilizer. was applied 
this year. The other part of the field was dressed” with stable 
manure at the rate of fifteen loads per acre. The crop was King 
Philip corn, sown in drills with a wheat drill sowing at the rate of 
one and one-fourth bushels, but only dropping seed in two rows 
at the rate of ten quarts per acre. The distance between the 
drills was three and one-third feet. 
The yields from plats a and b were comparatively low, showing 
the stand of corn was poor, rather than any after effect of ferti- 
lizer. Presuming the stand of corn to have been fairly even on 
_ the other plats, the yields from the unmanured plats e. and j. (o 
bore B & W corn), were at the rate of 24,200 and 21,440 pounds 
‘per acre. Comparing the yields of the other plats with the mean — 
of these, g and d yielded respectively 500 and 1,300 pounds 
greater than the mean, but both are less than the yield frome. 
The plats which have given yields greater than the above mean 
and also greater than e, are ¢, f, h, k and 1. 
Considering the little influence of the application the first year,* 
these differences seem to be rather more dependent on the stand of 
_ corn than anything else, especially as no difference of growth has 
been noticeable during the whole season. The table appended 
shows the crop actually harvested, and its rate per acre, with the 
increased yields above the mean of the unmanured plats wherever 
an increase occurred.
