Rice: Barnyardgrass Competition Trial


J. A. Dusky, Weed Scientist


This study is being conducted for the second year and is
part of a southern regional weed biology project and a project
being funded by the National Rice Council. The study is being
conducted in the same manner throughout the rice growing region
of the Southern U.S. The objective of this study is to determine
the influence of barnyardgrass (Echinochloa crus-)alli) density
and duration of competition on rice yield and yield components.
'Lebonnet' and 'Gulfmont' rice were seeded at 100 lb/acre on May
21, 1990. Barnyardgrass seed was planted with a junior planter
between rice rows on the same day. Plots were established by
thinning the barnyardgrass seedlings to specific densities June
4th through 6th. Plots were 4 m2 and were arranged in a split-
plot design with 5 replications. Main plots are rice variety and
subplots are weed density and time of removal. Densities of
barnyardgrass are 0 (control) and 2 or 40 barnyardgrass
plants/mi. Duration of interference periods are 21, 42, 63, and
full season (126 days). Data being collected are weed biomass at
time of removal, weed density, rice grain yield, straw yield, and
yield components.

Variety Demonstration and Seed Increase


C. W, Deren

Thirteen entries from the variety trials have been planted
for observation and seed increase. These include the recent
releases Millie, Alan, Katy, Maybelle, and Texmont. Also
included are 049 and 072, potential releases and six selections
from the 1988 URN. All plots are 1.2 x 6.0 and seeded at 100
kg/ha (90 Ib/ac).

GIBBERELLIC ACID SEED TREATMENT


Frank J. Coale, Extension Agronomist

Gibberellic acid (GA) is a plant growth regulator that has
been shown to be effective in accelerating emergence and aiding
in the development of uniform stands of semi-dwarf rice.
Typically applied as a seed treatment or foliar spray, GA
promotes elongation of the mesocotyl and coleoptile after
germination. In the Everglades Agricultural Area (EAA), the
proposed benefits of enhanced elongation of the mesocotyl and/or
coleoptile of semi-dwarf rice varieties include: 1) promotes
rapid and uniform emergence; 2) allows for deeper planting; 3)
promotes taller seedlings; 4) allows for earlier flooding; 5)
improves rice competition with weeds.

Experiments are being conducted at three locations in the
EAA to evaluate the response of 'Lemont' rice to GA seed
treatments. The GA was applied as "Release" (Abbott
Laboratories) at 0, 1, or 2 g/cwt seed. "Release" is 10% GA and
is applied to the seed rice by standard mist-treating equipment.
A total of 25 replications of the three rates of "Release" are
being evaluated in 1990.

The table below presents the average seedling response to
"Release" for all plots at all locations. These are preliminary
data and have not been thoroughly evaluated or subjected to
statistical analyses.

Uniform Rice Nursery and 1989 URN Selections


C. W. Deren

This year the Uniform Rice Nursery was divided into an early
test and a mid-season test. All lines were replicated twice.
Plot size was 1.2 x 4 m and seeding rate was 46 kg/ha (37
Ib/acre).


1989 URN Selections

Twenty-two lines were selected from the 1989 URN for
evaluation in a replicated test. These entries will be compared
to the check cultivars Lemont, Gulfmont, and Lebonnet. Plot size
is 1.2 x 6.0 m and seeding rate is 100 kg/ha (90 Ib/ac).

1990 Variety Trials


C. W. Deren


The objective of rice variety trials is to evaluate
cultivars, especially new releases, for production in the
Everglades. Two tests were planted, a very early maturity
(VERPT) and an early-midseason maturity (MERPT). Both tests were
planted on 26 March '90 and seeded at 100 kg/ha (90 lb/ac).
Plots were 1.2 x 6 m and replicated 5 times. Data will be taken
on emergence, heading date, plant height, and grain yield in
first and ratoon crops.

VERPT entries include the recently released cultivars Alan,
Millie, Texmont, and Maybelle, plus three experimental hybrids
(RA 2015, RA 2033, RA 2039) and 88 URN 10, an experimental line
selected in Florida. New or potential releases in the MERPT are
Katy and 049 and 072. In addition, 5 selections from the 88 URN
are also being evaluated.

EFFECT OF FUNGICIDES ON RICE DISEASES AND YIELDS


L. E. Datnoff
Plant Pathologist

There are several important diseases of Florida-grown rice
such as blast, brown spot, and sheath blight. Very little
information is available on the impact of these diseases on rice
yields or managing them by using fungicides in the Everglades
Agricultural Area. In addition, chemical inputs such as fungicides
are being questioned and challenged by the public and other
environmental groups because of being suspected carcinogens or
potential threats to agricultural land and water. These social
concerns have already caused the withdrawal of several registered
fungicides from the market and made questionable the re-
registration of others. Consequently, other experimental
fungicides need to considered as possible future replacements. The
purpose of this study is to evaluate registered and experimental
fungicides for their efficacy in controlling important rice
diseases and determining their effect on yield.
