New Sweetpotato
Clones Produce High
Root Yields
Each year, the National Sweetpo-
tato Collaborator's Group coordinates
sweetpotato variety trials to judge the
performance of new clones under a
wide range ofenvironmentalconditions.
Two new sweetpotato clones, L-87-96
and L-86-33, were evaluated in AAES
research at the E.V. Smith Research Cen-
ter, Shorter, and the Chilton Area Horti-
culture Substation, Clanton, where they
were compared to traditional clones
grown in Alabama.
Plantings were made at both loca-
tions in early July and harvested in mid-
October. Fertilizer rates of 80-50-150

At Clanton, fertilizer was incorporated
at planting. Irrigation was applied at
planting at Shorter and 0.75 inch of wa-
ter per week (9.75 inches total) was ap-
plied at Clanton.
Raised beds spaced 6 feet apart
were used at Shorter. Traditional bed-
ding procedures and between-row
spacings of 3.5 feet were employed at
Clanton. The within-row spacing at
both locations was 1 foot. Plots were
harvested after approximately 100
days of growth.
At Shorter, seven
clones were evaluated
under nonirrigated con-
ditions and raised beds.

tions of the raised bed

Jet and Beauregard, 171 and 151 bush-

The yields of U.S. No. 1 roots ob-
tained with L-87-95 (249 bushels per
acre) and L-86-33 (169 bushels per acre)
were similar to or greater than the high-
est yields obtained with the standard
clones. The yield of marketable roots
obtained with L-86-33 (319 bushels per
acre) was greater than with the stan-
dard clones, except for Beauregard,
which produced 374 bushels per acre.
L-86-33, the only numbered line
evaluated in 1991 that was also in-
cluded in the 1990 trial, produced the
greatest yield of U.S. No. 1 and total
marketable roots during 1990 at this
location. However, the highest mar-
ketable yield obtained at Shorter in
1991 (460 bushels per acre) was ob-
tained with the other new clone, L-87-
95. This was approximately 25 per-
cent greater than the marketable
yield obtained with Beauregard, the
highest yielding standard clone in the
trial. Beauregard, a recent Louisiana
release, and the two new clones evalu-
ated had the greatest potential for pro-
duction of U.S. No. 1 and total mar-
ketable roots at this location.
Four clones were evaluated at
Clanton under irrigated conditions on a
sandy soil. Cordner and Jewel pro-
duced only 45 and 35 bushels of U.S.

whereas yields with the new clones
were at least three times greater than
the average of these standards. High-

New Varieties of Southernpeas Released
Two new varieties of southern-
peas with unique characteristics have
been released by the Alabama Agricul-
tural Experiment Station. These new
peas resulted from long-term breeding
research seeking varieties with im-
proved horticultural characteristics
and resistance to insects and diseases.
AUBe, one of the new releases, is a
nonvining blackeye type which is ex-
pected to be popular for home garden
and fresh market uses. AUBe sounds
like the name of the Auburn University
mascot, Aubie, and the letters abbrevi-
ate Auburn University Blackeve. The
nonvining growth habit makes it espe-
cially convenient for gardeners with
limited space. Pods are produced level
with or above the foliage and are easy
to pick, detach from the peduncles, and
shell.
AUBe has a high level of resistance
to root-knot nematodes and is less sus-
ceptible to cowpea curculio than other
blackeye varieties. Only mild symp-
toms of mosaic virus have been ob-
served during numerous years of test-
ing. AUBe has produced well in yield
trials throughout the South. Its yields
are about equal to Pinkeye Purple
Hull, greater than California Blackeye
No. 5, and only slightly less than the
high yielding crowder 
variety,
Mississippi Silver, tables 1 and 2.
Genegreen is the other variety re-
leased by the AAES. It combines char-
acteristics of a persistent green seedcoat
and black eye and has potential to be an
excellent fresh market type blackeye.
The persistentgreen seedcoat trait gives
Genegreen an intense mature green
seed color, making it extremely attrac-
tive as a fresh, shelled product.
Genegreen has performed
trials since 1986, aver-
aging 2,623 pounds per
acre of shelled vield
compared to Pinkeye
Purplehull-BVR with
2,250 pounds per acre
and Mississippi Silver
with 2,741 pounds per
acre. It has a slightly
viney bush type of
growth habit and is
considered medium-
early in maturity.
Average pod length
at the mature green
stage is 7.5 inches. The
pods are green when
fresh, medium brown
when dry, and are pro-
duced level with or
above the foliage. The
seeds retain their green
color when dry, but may
fadeto white if exposed
to sunlight for 7-10
days after podsare dry.
well in yield
Signiticant fading occurs it pods are
notharvested within 1 week ofdrying.
Seeds are small to medium sized and
are oval to kidney shaped, with a small
black eye on the olive green seedcoat.
Genegreen has resistance to blackeve
cowpea mosaic virus (B1CMV).

Color of Plastic Mulch Affects Tomato Yields
and Harvest Dates
Polyethylene mulches are widely
used in production of fresh market to-
matoes to increase yields, promote ear-
lier harvest, and assure high quality
fruit. Such benefits have been attrib-
uted to effects of mulch on soil tem-
perature, water relations, fertility, and
weed control.
Mulch surface color can change the
quantity of light and spectral balance
reaching the plants, which affects
growth and fruit production. Research
has shown that plants grown on red
mulch had the greatest yields of
early-maturing fruit and produced
the least amount of foliage. Plants
grown on white or aluminum-colored
mulch had fewer fruit early in the har-
vest season, but produced more foliage.
An AAES study was implemented
to further evaluate the response of to-
mato plants to various mulches at the
E.V. Smith Research Center, Shorter.
Field plots were established there in
1990 on an Orangeburg sandy loam
soil. Five-foot-wide strips of commer-
cially available black, clear, white,
brown, and green polyethylene
mulches were applied to the soil by a
mulch layerapplicator. Aluminum and
red colored mulches were obtained by
spraying black plastic with all-purpose
enamel paints mixed with a mineral
spirit thinner (2:1). Trickle irrigation
tubing and methyl bromide fumigation
were applied in all plots by the mulch
layer applicator in a one-step operation.

cordance with established recom-
mendations for Alabama.
Fruits were harvested at the
breaker color stage. Five harvest dates
were required (July 3, 5, 9, 16, or 20).
Marketable yield consisted of fruit
graded U.S. No. 1 or No. 2. Yields, by
weight and by fruit count, were calcu-
lated for both marketable and
unmarketable fruit for each harvest
date. Season totals w'ere calculated
and yields were divided into early
(July 3 and 5), mid (July 9), and late
(July 16 and 20) harvest dates.
Plants grown on green or alumi-
num mulch produced more pounds of
marketable fruits for the season than
those grown on either black or white
mulch. Unmulched plants and plants
grown on red, brown, and clear
mulches produced intermediate
yields, table 1. Plants grown on black

Underground Drip
Fertigation System
Can Improve Sweet
Corn Production
In Alabama, where rainfall patterns
are unpredictable, sweet corn produc-
ers often benefit from the use of irriga-
tion. Underground irrigation offersspe-
cific advantages for the crop because it
reduces evaporation of irrigation water
and eliminates runoff of excess irriga-
tion water from the field compared to
surface drip irrigation. And under-
ground irrigation systems can help re-
duce the risk of plant diseases which
might occur when foliage or soil is wet.
A 3-vear AAES study at the Sand
Mountain Substation, Crossville,
evaluated the ability of an under-
ground drip fertigation system to sup-
ply both water and nutrients to the
plants. Urea-ammonium nitrogen was
applied to the soil through under-
ground drip fertigation, aboveground
drip fertigation, and surface dr, meth-
ods. Dry nitrogen (ammonium nitrate)
was surface band-applied as a control.
Nitrogen rates of 60 to 120 pounds per
acre were applied to sweet corn after
planting in either two or four applica-
tions bv each of the three methods. Dry
phosphorous and potassium fertilizers
were applied to all treatments accord-
ing to soil test recommendations.
Underground drip pipe tubing
was laid in a 9-inch-deep furrow along
each row and covered with surface soil
continued on page 4
Drip Fertigation, continued
in a one-step operation using
a three-point hitch rig attached
to a medium-sized tractor.
Sweet corn was subsequently
planted in each row with
both the aboveground and
underground systems. Rain-
fall and number of ears of
sweet corn produced were
recorded. Rainfall data are
given in table 1.
In 1987 and 1989, there
were no significant differ-
ences in yields regardless of
number, rate, or method of
nitrogen applications. This
was probably because ad-
equate to above normal
rainfall was available dur-
ing the sweet corn's repro-
ductive growth stage, table 2.
Underground fertigation at
the 120-pound nitrogen rate
during years of less than adequate rain-
fall increased the number of market-
able sweet corn ears over the dry
nitrogen application method. Al-
though underground fertigation had
no yield advantage over the

foliage gradually covered the mulch,
reducing the mulch's ability to reflect
light into the plant canopy. This al-
lowed an increase in the aphid popula-
tion as the growing season progressed.
APM, WPM, and YPM treatments pro-
duced the highest squash yields as
compared to other treatments. Yields
on bare soil are the lowest reported in
the table.
Results of this study showed that
APM reduced the incidence of both vi-
rus diseases and aphids by delaying
the onset of the disease for approxi-
mately 3 weeks, thus extending the
harvest period for marketable squash.
Yield of squash was higher and fewer
virus-infected squash fruits were har-
vested from APM than from BPM, BSI,

yellow mosaic and cucumber mosaic
viruses, it has the potential to be an
effective cultural practice in Alabama.

rieties listed in the table, all had green
pods except Goldmarie, which had yel-
low pods. Rattlesnake and Selma
Zebrina had striped pods. Most variet-
ies required 50-54 days to reach first
harvest in 1991. Early Riser, Goldmarie,
Precores, Selma Star, and Selma Zebrina
required only 47 days, while Blue Lake,
Genuine Cornfield, and Alabama No. 1
required 61 days to reach maturity.
Results from 3 or more years of
variety testing are needed before new
varieties are recommended. However,
the 2 years of results reported here
indicate that both Bertina and Rattle-
snake, which maintained highest
yields during each of the 2 testing
years, may merit small test plantings
by growers. Other varieties appear to
be sensitive to changes in the environ-
ment and/or management conditions,

ATH-9 has an indeterminate
growth habit and oblate fruit shape.
Its fruits are flavorful with good exter-
nal and internal color, and are firm
enough for shipping. ATH-876 also is
an indeterminate type, its fruit are more
globe shaped and are slightly better
colored than ATH-9. Both hybrids had
fair resistance to early blight and excel-
lent resistance to leaf mold.

trial, ATH-9, ATH-876, and ATH-234
have the potential to make a contribu-
tion to the improvement of fresh market
or home garden tomato varieties avail-
able to Alabama growers.
