Bulletin 201, Variety Tests of White Potatoes


out the season, and harvested at the same time. Particular at-
tention was given the matter of foliage production and inhibition
of weed rowth. Spauldings produced probably slightly less foli-
age than either the Triumphs or Green Mountains, and the Cob-
blers slightly less than the Spauldings, but the comparative dif-
ferences were small. In spite of a trifle smaller amount of foli-
age in the Cobblers, no more weediness was observed in the rows
of this variety. Nowhere was there any hint of difficulty from
this source.
 Average increases over Spauldings in U. S. No. 1 grade, as
indicated in Table I, of 21, 24, and 24 percent for Bliss Triumphs,
Irish Cobblers, and Green Mountains respectively, indicate pos-
sibilities favorable towards the growing of varieties other than
that which is now grown almost exclusively. However, it is not
within the scope of these investigations to determine whether
or not any white or red varieties would be accepted in large
quantities by the northern markets at satisfactory prices at the
time they are looking for the pink-skinned variety which Florida
is accustomed to ship at that particular time. Considering the
cooking quality of these different varieties, it would seem that
there should be but little difficulty in marketing should they
once become established. Theoretical calculations based on even
the comparatively low averages (see table) obtained during the
five years' trials yield financial increases per acre at Spaulding
sale prices of $5.50 per barrel for primes and $2.50 per barrel
for seconds, as follows:
