INTRODUCTION C 0 2 199


Watermelons are the number 1 vegetable crop in northwest Floridaareage wP s but is
behind tomatoes in value. Estimated spring production is planted in about 6000 acres and has
become fairly stable. The variety situation is changing rapidly. The seed companies are
releasing many new hybrid varieties. Seed is expensive and growers are reluctant to try an
unproven variety. In an ongoing evaluation program 20 varieties were evaluated for production
at the NFREC, Quincy.


Materials and Methods

This evaluation contained 20 watermelon cultivars and was conducted at the North
Florida Research and Education Center on Orangeburg loamy fine sand. Seed were planted on
February 20, 1990, into 1 1/2 in. X 1 1/2 in. expanded polystyrene flats. Transplants were
placed in the field on March 28, 1990. Plant spacing was 3 ft. in row X 10 ft. between row.
The watermelons were grown with black polyethylene mulch and trickle irrigation. Total
fertilizer applied was 117-36-117 lb/A N-P205-K20. Weed, insects and diseases were controlled
with timely applications of registered chemical products.

Plots were 1 row X 36 ft. with 4 replications in a randomized complete block design.
Watermelons were harvested 3 times from June 8 June 21, 1990.


Results

The following table contains yield (cwt/A), average fruit weight (lb) and fruit size
distribution (%). There were few significant differences in yields which ranged from 327.4
cwt/A ('Cardinal') to 659.1 cwt/A ('Crimson Sweet'). All entries except 'Cardinal' had average
fruit weights of more than 20 lb. 'Cardinal' was the only entry with no fruit of more than 30
lb.
