Composition of Florida-Grown Vegetables 13

above average in protein, calcium, magnesium and phosphorus;
while those from Hastings averaged high in potassium and phos-
phorus; and those from Bradenton, below average in protein
and phosphorus. Samples from Hastings and Belle Glade aver-
aged higher in iron than samples from Winter Garden and
Bradenton.
 Beans.-Table 1 shows the range and average composition of
25 bean samples collected from the vicinities of Belle Glade,
Homestead and the lower east coast section of Palm Beach
County. They show significant differences in protein, calcium
and phosphorus percentages between areas. Samples from the
Belle Glade area were above average in protein but below average
in phosphorus, while samples from the Homestead area were
above average in phosphorus and samples from the Palm Beach
area, below average in calcium.
 Celery.-Table 1 shows the average composition of 27 celery
samples collected from the vicinities of Belle Glade, Sanford
and Sarasota. Analyses of celery stalks show significant differ-
ences in calcium, potassium and phosphorus percentages between
areas. Samples from the Belle Glade area were above average
in potassium. Those from the Sarasota area were below aver-
age in calcium but above average in phosphorus.
 Tomatoes.-The composition of tomatoes collected from Home-
stead, Ft. Myers, Ft. Pierce and Collier County is shown in
Table 1. They show significant differences in protein, calcium,
potassium and phosphorus percentages between areas. Samples
from Rockdale soils and Perrine marl in the Homestead area
were above average in calcium, while those from Ft. Pierce and
Ft. Myers were below average in this element. In phosphorus,
samples from the Ft. Pierce area were above average, those from
Collier County below average. Samples from the Ft. Myers
area averaged lower in nitrogen than those from Ft. Pierce and
Collier County. Samples from the Perrine marl at Homestead
averaged higher in potash than those from Ft. Myers and Collier
County.
 Collards.-Table 1 shows the average composition of collard
leaves and leaf petioles collected from the vicinity of Quincy.
The collard leaves averaged 86 percent more calcium and 47
percent more iron than the petioles. The leaves also contained
more magnesium and phosphorus but less potassium. It is
worthy of note that the collard leaves contained higher percent-
