DOUBLE CROPPING TOMATOES AFTER TOMATOES


Block 10 P. H. Everett


Purpose: To develop fertilizer management practices for growing a spring tomato crop
using the same mulched beds after completing a fall crop of tomatoes.

I. Fall 1981 Tomato crop (Non-staked):
The following fertilizer rates and placements were evaluated for their
effect on tomato yield and fruit size.

Fertilizer (18-0-25) rates:
1. 1000 lb/A (14 lb/100 bed feet)
2. 1500 lb/A (21 lb/100 bed feet)
3. 2000 lb/A (28 lb/100 bed feet)

Fertilizer (18-0-25) placement:
1. Top banded banded in 1" deep grooves 9" to each side of plant row
2. Bottom banded banded on false bed 9" to each side of plant row,
then bedded over to a 4" depth

*In addition to the 18-0-25 fertilizer, all plots received a uniform
application at 5-8-8-1.8 + F-503 micros at 500 lb + 30 lb/A (7 lb + 0.4 lb/100
bed feet). The 5-8-8 was applied in a 30" wide band on a false bed, then
bedded over to a 4" depth.
The fall crop (cv. FTE #12) was transplanted on Sept. 15, 1981 and harvested
twice (Dec. 7 and 18, 1981).
The following table shows the effects of fertilizer rate and placement on
the marketable yields and fruit size for the fall crop.

II. Spring 1982 Tomato Crop:


Procedure
1. 12/29/81 Vine from fall crop sprayed with Paraquat Dec. 29, 1981
and left in place
2. 1/21/82 Tomato seedlings (cv. Duke) transplanted Jan. 21, 1982.
These were placed half-way between the old tomato plants.
3. 1/26/82 The 60' long plots used for the fall crop were divided into
3 subplots. Subplots were fertilized as follows:

Subplot "x" No fertilizer (residual only)
Subplot "y" Liquid 8-0-8 at 125 lb N and 125 lb K20/A,
or 4 oz of 8-0-8/plant
Subplot "z" Dry 23-0-22 at 125 lb N and 120 lb K20/A,
or 1.8 oz of 23-0-22/plant

Both liquid and dry fertilizers were placed in 2" deep holes 9" to each side of
each plant.
