Florida Experiment Station.
The Care of Irish Potatoes Harvested in the
Spring and Held for Fall Planting.
There having been a great number of inquiries as to
the keeping of Irish potatoes from the spring crop for
fall planting, it seems advisable to give the experience of
the Florida Experiment Station in the form of a press
bulletin so that it may reach the farmers in general. Be-
fore giving the method employed at the Station with un-
failing success, it does not seem inexpedient to eall atten-
tion to some of the other methods tried and the difficulties
Storing potatoes in oat straw proved a failure on ac-
count of the tendency of the potatoes to decay.
Spreading the potatoes on a board floor was unsuc-
cessful as the potatoes turned green and shriveled, being
then unfit for either shipping or planting.
On trying a mixture of lime and dry sand, in the pro-
portion of one pint of lime to a bushel of sand, it was
found that, while the potatoes did not decay, they were no
longer viable, the lime apparently killing the eyes and
thereby preventing them from sprouting successfully.
Dry sand alone produced better results.
The method that has proved uniformly successful at
the Station has been to take a slat crate, place a layer of
pine straw in the bottom, then a layer of potatoes, cover-
ing them with a layer of pine straw, and continue the
process until the crate is filled. Finally the crate is
covered with a layer of pine straw and stored in the barn
without further attention. On taking the potatoes out in
the fall they have been found to be sound and fresh in
appearance and there has been no difficulty as to their
sprouting when planted.
Fall planting at the station has just been completed.
The potatoes cared 'for as above described were in prime
condition; in fact, they were as good as, if not better
than, seed potatoes shipped from the North. The variety
of potato that has been used with the greatest success at
the Station is No. 4 Rose, it never having been affected
with black heart here. As regards the yield, out of
sixty-seven varieties planted in the experiment, it proved
the most prolific.
