New York AGRICULTURAL EXPERIMENT SraTION. 231 
On the B plats the seeding was lighter in the three forms where 
the largest amounts was used, and at the same rate for two and 
one-eyed seed. This change was made necessary because the 
supply of larger tubers of even size was used up and a smaller 
grade was necessarily used for seed. 
The B plats were double the size of the F plats, each being one- 
tenth acre. Hence the area covered by this experiment is one-half 
acre on the F plats, or one-tenth to each form and different 
amount of seed, and one acre on the B plats or one-fifth acre for 
each different amount of seed. 
The yields from these small areas on each plat, all telling the same 
story, from the vegetation of the plants up to the harvest results, . 
_ when combined, point very decidedly to ove conclusion. And, when 
seconded by such cther results as are appended, ought to carry 
conviction that light seeding for the potato crop is unprofitable, 
and that heavy seeding alone is compatible with successful work 
for the potato culturist. 
Just how much to plant for the greatest profit depends so much 
on conditions of the market at both ends of the season, the 
fertility of the soil and other considerations that it is obvious ; no 
definite amount can be set as the best. In the above-recorded 
experiment, with seed and crop at the low price of twenty-five 
cents per bushel, the greatest profit was with the most seed, where 
the seed tubers weighed an average of five ounces each. 
In an experiment with many varieties on a small scale, at the 
Maryland Station, in 1888, the greatest rate of profit was from 
their greatest weight of seed, where ten-ounce tubers were planted 
at the rate of sixty bushels per acre. 
In three years trials compiled at the same place* by far the 
ereater profit was shown to result from whole medium-sized 
tubers. These three years results are so in harmony with the 
above that the following is abstracted from page 24 of Bulletin 2, 
quoted above:
