FOLIAR NUTRIENT (TRISERT) STUDY ON SWEET CORN, SANFORD, FL, 1987

J. M. White and Ivalou Hancik


Silver Queen sweet corn was planted on March 16, 1987, on Myakka
fine sand. A preplant fertilizer application of 500 Ib/acre of 5-5-8
was made on March 16. Cool weather accompanied by high rainfall (Table
1) were not favorable for corn growth, and the initial stand was disked
and replanted on April 4, 1987.

Sixteen plots (4 treatments x 4 replications) were established in
the field. Each plot measured 10 ft wide and 40 ft long. Additional
fertilizer applications were made as follows: April 20, 500 lb/acre of
5-5-8; May 5, 500 lb/acre of 10-4-10, and May 14, 296 lb/acre ammonium
nitrate. Insecticides and nematicides were applied as needed and as
suggested in the Extension Service Control Guide.

Lay-by (May 15), first tassel (May 27), and completion of
pollination (June 4) applications of trisert foliar nutrient were made
with a single nozzle, hand-held sprayer. All four rows of the plot were
sprayed; subsequent phytotoxicity was noted.

Plant height and height to the first ear was recorded three days
prior to harvest.

The two center rows of each 4-row plot were harvested on June 22,
1987. Data collected at harvested included: total numbers of ears,
total number of marketable ears, total marketable weight, maturity, tip
fill, ear width, ear length, and average ear weight. Table 2 summarizes
data collected in this experiment.

Although the level of phytotoxicity at 5 and 10 lb of Trisert per
acre was significantly greater than that observed in the check plot or
at 3 lb Trisert per acre, final yield among all treatments was
comparable and no significant differences were apparent.
