New York AGRICULTURAL EXPERIMENT STATION. 377 
Where so large a part of the tubers were rotten, it is probable 
there were many grown which were not weighed at all. There 
was a poor “stand” of plants, many missing “hills,” on these 
plats due to heavy rains early in the season. 
FF plats.— Nos. 3 to 12, inclusive, have produced several crops 
of potatoes in succession, and this is the third year this crop has 
received the same formulas of fertilizers on these plats. Nos. 1 
and 2 have been planted to cucurbits and turnips, and were fal- 
lowed part of the time. This trial of different amounts of seed 
covers Plats 2 to 12 inclusive, but there is some doubt as to 
whether No. 12 was planted and harvested in the same 
order, hence the yield from that plat is dropped. The rows 
on Plat 12 :were at right angles with those on the 
other eleven plats. The first eleven of these plats were planted 
with rows running crosswise to facilitate cultivation and the 
application of arsenites by horse power. No. 12 is the first of 
another block with a wide path between it and No. 11. The rows 
_were three feet eight inches apart, and the “hills” were eighteen 
inches apart in the row. This seed was all carefully selected of 
uniform size, so the weight for each row of twenty-two “hills” of 
each different form and amount was a duplicate of all the others 
of its kind. 
These weights were of whole tubers, five and one-half pounds 
per row; half tubers, three and three-fourths pounds per row; 
quarter tubers, two and one-half pounds per row. 
The order of planting was, beginning on the northwest corner, 
a row of whole tubers across the north ends of the plats. The 
second row was of half potatoes of larger size for seed, and the 
third row was planted with quarters of still larger tubers. The 
next three rows were a repetition of the order and amounts of 
seed and of the same kind (White Star), but was grown on differ- 
ent soil. The third three was the same, but was-grown on another 
farm. The last nine of the eighteen rows per plat were duplicates 
of the first nine. The spaces between plats were left blank and 
were cultivated. There was a marked difference in the growth of 
" _ tops early in the season, which gradually became less later. The 
tops from whole seed obtained a start of the others and made a 
stronger growth. The following table shows the yields by plats 
and different amounts and forms of seed :
