Tomato Cultivar Evaluation, Spring 1990

S. M. Olson and J. M. Snell
Associate Professor and Sr. Biological Scientist


INTRODUCTION


Spring tomato production in northwest Florida has stabilized at around 2000 acres. As
a continued effort to find more adaptable cultivars twenty entries were evaluated at the NFREC,
Quincy during the spring 1989 season. ,:fl rc;

Materials and Methols

This evaluation was conducted at the North Florida Resea rC an'Fi.di aon Ce ter on
an Orangeburg loamy fine sand soil. Tomatoes were seeded in 1 /2-ih-.7Xl1/2 in. ex handed
polystyrene flats on February 7, 1990. Transplants were placed in the field on March 21, 1990.
Plant spacing was 20 in. in row and 6 ft. between rows (7,620 linear ft/A). The tomatoes were
grown with black polytheylene mulch and trickle irrigation. Total fertilizer applied was 195-60-
195 lb/A N-P205-K20. Plots were one row 20-ft. long and were arranged in a randomized
complete block with four replications. Weeds, insects and diseases were controlled with timely
applications of registered chemical products. Plots were harvested from June 7 to July 3, 1990,
and were graded according to size and marketability. There were five harvests.


Results and Discussion

The following table is a listing of seed source, yield (25 lb cartons/A), percent
marketable fruit and average fruit weight (oz.) for all entries evaluated. Extra large fruit
generally sells for the highest price per carton. The majority of spring tomato acreage in north
Florida is currently planted in the variety 'Sunny'.

The entries 'XPH 5796', '7307' and 'NC 87345' produced more extra large fruit than
'Sunny'. '87-27' produced a higher total yield than 'Sunny'. Percentage marketable yield
ranged from 66.1% ('Bingo') to 84.7% ('87-27'). 'Bingo' had the largest average fruit size at
8.9 oz.
