POTATO VARIETY AND SEEDLING SELECTION TRIALS AT HASTINGS, -FLORIDA-
R. M. Hosford, Jr., Asst. Plant Pathologist-&
J. R. Shumaker, Asst. Horticulturist

Eight potato varieties and eight seedling selections were grown for comparison
with Sebago, the standard variety grown in Northeast Florida. The experimental
conditions and procedure were as follows: Soil, Rutledge fine sand; plot size,
single rows 40 inches apart and 10 feet long; seed size, 2.0 ounces each; seed
spacing, 12 inches in the row; replications, five; planting date, January 31,
1967; fertilizer, 2500 pounds 6-8-8 per acre in a band on each side of the row
on January 31, 1967 and 125 pounds of ammonium nitrate per acre applied as side
dressing on March 20, 1967; fungicide, Maneb; insecticide, Thiodan; harvest
date May 16, 1967 -- 105 days after planting. Because of dry weather through-
out the growing season the potatoes were grown under irrigation. A severe
freeze on February 26, 1967 killed the vines to the ground level, but the vines
grew out again and produced a good crop.
