Abstract: In the arid and semiarid western USA, alfalfa
(Medicago sativa L.) grown for forage requires large amounts
of water for high productivity. Managing alfalfa to achieve
the best possible water-use efficiency (WUE) is essential for
the crop to remain competitive for water supplies both within
and outside agriculture. This study was conducted in the San
Joaquin Valley of California, to define alfalfa forage yield
and plant water relation responses of three alfalfa cultivars
(CUF 101, Moapa 69, and WL 318) to contrasting irrigation
intensities and establish critical plant water-status values
for irrigation scheduling. A single line-source sprinkler
system provided a variable water supply. The soil was a
Hanford sandy loam, silty substratum (coarse-loamy, mixed,
nonacid, thermic typic xerorthent). Maximum total season crop
evapotranspiration (ET(c)) of 1000 mm gave 26.3 Mg ha-1 of hay
yield that was similar for the three cultivars. A linear hay
yield (Y(h))-ET(c) relationship was defined as Y(h) = -0.212 +
0.0265 ET(c) (r2 = 0.82). Water-use efficiency, 23.1 Mg ha-1
dry matter per meter of water used as ET(c), was comparable
with other C(3) species. As midday plant water potential
declined below -1 MPa, yield reductions were observed for all
cultivars. Increased crop water stress index (CWSI) was
correlated (r = 0.84) with declining midday plant water
potential below the -1 MPa yield-limiting midday plant water
potential threshold. Absolute values of midday plant water
potential or CWSI associated with a given yield reduction were
cultivar-dependent; Moapa 69 and WL 318 responded alike, but
each differed from CUF 101. Plant-based water-status
measurements provided a practical and reliable index for
assessing the adequacy of supplied irrigation water.

Abstract: Volume of water captured in a container as a
function of sprinkler type, spacing, plant type, and container
size was measured for marketable-sized plants. Percent water
captured was calculated and a model to predict this value
derived. Percent water captured was inversely related to the
leaf area contained in the cylinder over the container when
containers were separated, and with total plant leaf area at a
pot-to-pot spacing. This relationship was independent of leaf
curvature (concave vs. convex). Canopy densities were less
related to percent water captured than leaf areas. Irrigation
application efficiencies separated by spacing ranged from 37%
at a close spacing to 25% at a spacing of 7.6 cm between
containers. Container spacing, canopy shedding, and possibly
some canopy retention of water later lost by evaporation were
determined to be the main factors associated with the low
efficiencies. The results suggest that higher irrigation
application efficiencies would be maintained only if plants
were transplanted to larger containers before reaching maximum
canopy size rather than spacing existing containers to achieve
more room for canopy growth.

Abstract: Studies were conducted to evaluate the effect of
water application medium moisture deficit, water application
rate, and intermittent application on water application
efficiency {[(amount applied - amount leached)/amount applied]
X 100} of spray stake-irrigated, container-grown plants. Pine
bark-filled containers were irrigated to replace moisture
deficits of 600, 1200, or 1800 ml; deficits were returned in
single, continuous applications of 148, 220, or 270 ml-min-1.
Efficiency was unaffected by medium at a 600-ml deficit was
irrigated with 400 or 600 ml (65% and 100% water replacement,
respectively); deficits were returned in a single, continuous
application or in intermittent 100-ml applications with 30-min
intervals between irrigations. Application efficiency was
greater with intermittent irrigation (95% and 84% for 400- and
600-ml replacement, respectively) than with continuous 100-,
or 150-ml aliquots with 20, 40, or 60 min between applications
in a factorial design. Efficiency increased with decreasing
application volume and increasing time between applications.
Highest efficiency (86%) was achieved with an irrigation
regimen of 50-ml applications with at least 40 min between
applications, compared to 62% for the control treatment (a
single, continuous application of 600 ml). Our results suggest
that growers using spray stakes would waste less water by
applying water intermittently rather than continuously.

Abstract: In Virginia, as in many states, priority to
streamflow is held by riparian landowners who are
predominantly agricultural users. The streamflow may also have
a high potential value to nonagricultural users who do not
have riparian rights. The potential benefits of transferring
streamflow priority rights from agricultural to non-
agricultural use were evaluated using simulation for an
eastern Virginia watershed. Lowering irrigators' priority to
streamflow reduced crop yields and irrigated returns in some
years because of inadequate water supplies. However, the
transfer of priorities increased the likelihood that the urban
reservoir would be able to withdraw water from the stream
without interruption. As a result, priority trades reduced the
size of reservoir needed to meet a given water requirement by
municipal users. The resulting savings in reservoir
construction and maintenance costs more than offset the losses
to irrigators. Net savings could be achieved even if the
reservoir were required to release water periodically to
maintain a minimum level of instream flow. The conclusion is
that the state should encourage trading of access to
streamflow in order to increase the use efficiency of
streamflows. Alternative means by which the state can
facilitate water exchanges are discussed.

Abstract: Reuse of wastewater as an irrigation source for
turfgrass is becoming a more viable and appealing option in
arid environments where competition for good-quality water is
increasing. The objective of this research was to determine
the impact that varied leaching fractions, irrigation
salinity, and soil types had on root growth and distribution,
and fractional water uptake of bermudagrass [Cynodon dactylon
(L.) Pers.]. Bermudagrass was grown for a 2-yr period in large
columns packed with three different soil types (sandy loam,
silt loam, and clay). Saline water was synthesized and applied
at three different salinity levels (electrical conductivities
of 1.5, 3.0, and 6.0 dS m-1). Irrigations were applied 3 d
wk-1 at a rate beyond measured evapotranspiration (ET) to
establish three different leaching fractions (0.09, 0.18, and
0.27). The soil salinity (ECe), soil solution chloride (CI-),
root density, and volumetric water contents were measured in
soil cores taken with depth and time. Dry matter of weekly
grass clippings was measured and recorded throughout the 2-yr
period. Plant water status was monitored by measuring canopy
temperatures and leaf xylem water potentials. Results
indicated that bermudagrass was very tolerant to the range of
salinity-leaching conditions imposed. However, differences
were noted by treatments, with the sandy soil showing as much
as a 25% yield decrement at the highest salinity level.
Salinity of the irrigation water (EC1), rather than soil
salinity (ECe), was more highly correlated with most of the
soil-plant-water relationships observed. Root length density
was best described by a hyperbolic function. Only limited
success was found in correlating root length density with
fractional water uptake. In addition, poor correlations were
found between soil salinity with depth and fractional water
uptake. These findings indicate that the ability to predict
water uptake based on root distribution and/or soil salinity
would be poor and that great

Abstract: Carbon isotope discrimination (delta) shows promise
for estimating water-use efficiency (WUE) in crop species.
Research was undertaken to examine delta and water relations
of tall fescue (Festuca arundinacea Schreb.) accessions and to
determine if low delta is associated with high gas exchange
WUE as predicted by theory. The accession PI 438522 had lower
a than the accession PI 231522 in both a dryland and an
irrigated field environment and at two sampling dates.
Correlations among delta, water potential, solute potential,
and turgor pressure were not significant under irrigation.
Under dryland conditions, correlations among these factors
were generally significant and positive for PI 49522, but not
significant for PI 231561. In a greenhouse experiment, plants
selected for low delta from the irrigated field environment
had lower delta and internal leaf [CO2] (Ci), and a higher
ratio of CO2 assimilation rate (A) to transpiration than high-
delta selections. This was true for both well-watered plants
and plants stressed with a -0.38 MPa polyethylene glycol
solution. Stomatal conductance and A were positively
correlated with delta, suggesting that lower stomatal
conductance was a factor leading to lower Ci and delta. The
results suggest that associations between water relations and
delta vary depending on accession and environment, but
selecting tall fescue plants for low delta does identify
genotypes with low Ci and high WUE. Using delta for germplasm
enhancement of WUE in tall fescue appears promising.

Abstract: Subsurface trickle and furrow irrigation of fresh-
market tomato (Lycopersicon esculentum Mill.), with or without
plastic mulch, were compared for three consecutive growing
seasons. Plots were irrigated when available soil water was
40% depleted. Marketable tomato yield was 22% greater for
plants grown with trickle irrigation than with furrow
irrigation. Use of black plastic mulch resulted in 31% and 16%
greater marketable tomato yield in Spring 1983 and 1984, than
similar bare-soil (unmulched) treatments, respectively. In
Fall 1983, use of white/black (top/bottom) laminated plastic
mulch reduced yields by 12% compared to similar unmulched
treatments. Total water (irrigation plus precipitation)
applied to furrow-irrigated plots nearly equalled pan
evaporation (Epan). Trickle-irrigated plots received less than
45% of Epan in all seasons, resulting in increased water-use
efficiency with drip irrigation. Trickle irrigation as applied
did not affect soluble salts concentration in the soils.

Abstract: Irrigations were applied to short-season cotton at
Halfway, Texas, using a LEPA irrigation system at intervals of
2, 4, 8, and 12 days in 1986 and at 3, 6, 9, and 18 days in
1987 and 1988. The four interval treatments were grouped for
analysis and referred to as 3D, 5D, 9D, and 15D. Irrigation
quantities at each interval were 0.4, 0.6, 0.8, and 1.0 times
a base irrigation amount (BI) which equalled estimated cotton
evapotranspiration (ET) less rainfall. The DRY treatments
received preplant irrigations only. The 3D treatments resulted
in higher cotton lint yield and seasonal irrigation water use
efficiencies than other irrigation intervals. Root length
densities in the 3D treatments were higher than in the 15D
treatment at both the 0.4BI and 1.OBI irrigation quantities.
Irrigation interval treatments caused small detectable
differences in seasonal soil water content at the 0.4BI
irrigation level. Average cotton lint yields were reduced as
irrigation amounts increased. The 0.4BI and 0.6BI treatment
yields were significantly higher than those of the 0.8BI and
the 1.OBI quantities. The 3D X 0.4BI treatment produced the
highest annual lint yield of 1134 kg/ha from average
irrigations totaling 81 mm/yr compared to the 15D X 1.OBI
(traditional) treatment which yielded 945 kg/ha from 202 mm/yr
of seasonal irrigation. Deficit irrigation of short-season
cotton using a LEPA system and a 3D interval can enhance lint
yield and conserve groundwater on the Southern High Plains of
Texas.

Abstract: The Southern High Plains of Texas represents the
largest contiguous cotton (Gossypium hirsutum L.) production
area in the USA. Water supply represents the greatest
limitation to production under rainfed conditions. Where
supplemental irrigation is used, growing season length
represents a major limitation to attainment of high yields of
desirable quality fiber and seed. The primary objective of
this research project was to determine the inter-relationships
between H2O, N, and heat unit supplies as they affect lint
yield of cotton. Field experiments were conducted during a 4-
yr period at a sandy soil (fine, loamy, mixed, thermic family
of Aridic Paleustalf) site. Water supply was varied through
irrigation with treatments ranging from dryland to fully
irrigated. Superimposed on the water supplies were N rate
treatments applied preplant and sidedress in a factorial
design. Lint yield (LY) was defined as a function of
components including plant density, bolls per plant and
average boll size. Regression analysis was used to determine
LY response to treatments. Lint yield was most highly
correlated with boll number per unit ground area with equal
contribution from plant density and bolls per plant. Water
supply was most responsible for boll number; however,
increasing N supply within each H2O regime resulted in a
positive response in boll number per plant. Multiple
regression analysis revealed that LY responded to H2O and N
supplies during the fruiting period to a greater extent than
to preflower supplies. Within any heat unit regime, LY was
maximized as water supply increased by maintaining a constant
ratio of 0.2 kg N ha-1 mm-1 H2O.

Abstract: Sweet corn (Zea mays L.) was irrigated using
randomized complete block and line source experimental designs
in 1984 and 1985 on a mixed, mesic Cumulic Ultic Haploxeroll
soil. Irrigations were scheduled when approximately 50% of the
available water was depleted in the root zone of the 100%
treatment to refill the zone to 0% to 100% of field capacity
(five irrigation levels). Four yield parameters were measured
for all plots: yield of all ears before husking, yield of good
husked ears, kernel yield (fresh), and total dry matter
production of plants and ears. Maximum relative total unhusked
ear yield and near-maximum evapotranspiration (ET) were
obtained at 85% of maximum water applied, indicating that high
yields can be maintained with deficit irrigation. Without
irrigation, only 44% of maximum yield was obtained. Maximum
water use efficiency (WUE), defined as the total unhusked ear
yield in kg.ha-1.mm-1ET, occurred between 407 and 418 mm of
ET. The maximum WUE corresponded to approximately 313 mm water
applied (WA); maximum yield, however, occurred within the
range of 449 to 518 mm WA. Irrigation treatments to achieve
maximum WUE were predicted to result in a 10% yield reduction.

Abstract: Water table observations from the 1000 ha watershed
of Mitchell Creek near Tarboro, NC, were used to field test
the water management model, WATRCOM. Soil properties and
channel boundary conditions from three sections of the
watershed along with weather data from years 1983 and 1984
were used to simulate the hydrology of the area with and
without channel water level control. Six transects containing
27 water table observation wells were selected for testing.
All simulations were based on measured field parameters and no
calibration simulations were made to optimize parameters to
fit observed data. A total of 14,000 daily water table
observations were compared with simulated data. The root mean
square error in simulated water tables at each well ranged
from 0.05 to 0.24 m. When the data were pooled by section, the
root mean square error ranged from 0.10 to 0. 17 m.

Abstract: Drip-irrigation scheduling techniques for fresh-
market tomato (Lycopersicon esculentum Mill.) production were
compared in three growing seasons (1989-91). Three regimes
were evaluated: EPK [reference evapotranspiration (ET,
corrected Penman) X programmed crop coefficients], ECC (ET X a
crop coefficient based on estimated percent canopy coverage),
and SMD (irrigation at 20% available soil moisture depletion).
EPK coefficients ranged from 0.2 (crop establishment) to 1.1
(full canopy development). Percent canopy coverage was
estimated from average canopy width + row width. Irrigation in
the SMD treatment was initiated at -24 kPa soil matric
tension, with recharge limited to 80% of daily ET(o). The EPK
and ECC regimes gave similar fresh fruit yields and size
distributions in all years. With the EPK scheduling technique,
there was no difference in crop response between daily
irrigation and irrigation three times per week. In all
seasons, ECC scheduling resulted in less total water applied
than EPK scheduling and averaged 76% of seasonal ET(o) vs. 86%
for EPK. Irrigating at 20% SMD required an average of only 64%
of seasonal ET(o); marketable yield was equal to the other
scheduling techniques in 1989 and 1991, but showed a modest
yield reduction in 1990. Using an SMD regime to schedule early
season irrigation and an ECC system to guide application from
mid-season to harvest may be the most appropriate approach for
maximizing water-use efficiency and crop production
productivity.

Abstract: In arid and semi-arid regions, where soil structure
is unstable, surface runoff due to seal formation reduces
irrigation water use efficiency. This study was conducted to
determine the efficiency of surface treatments in reducing
runoff and increasing wheat crop productivity. Surface runoff
from wheat plots on a non-sodic, silty clay loam soil
(Rhodudalf silty clay loam), sprinkler irrigated with a good
quality irrigation water, was collected using flumes and
collection boxes. Percentages runoff were 36.1% of the total
irrigation during the growing season for the control (Ct),
12.8% for phosphogypsum (PG), 1.4% for polyacrylamide plus PG
(PAM), and 1.1% for pitting plus PG (Pt) treatments. The
mulching effect of the growing canopy did not reduce runoff
during consecutive irrigations as the season progressed. Water
content in the profile was correlated with the amount of water
that infiltrated into the soil. The crop biomass production in
the Pt and PAM treatments was significantly higher than the PG
and Ct treatments (8.81 and 7.91 vs. 6.41 and 5.47 Mg ha-1,
respectively). The Pt and PAM treatments also gave
significantly higher grain yield (3.66 and 3.02 vs. 2.25 and
2.12 Mg ha-1, respectively). The Pt, PAM, and PG treatments
resulted in significantly higher irrigation water use
efficiency (IWUE) than the Ct. The PAM is the least known
treatment and is given special attention in this study. In
regions where water is scarce and costly, improving the
efficiency of irrigation by tillage or soil ameliorants should
be considered.

Abstract: Strawberry plants (Fragaria X annanasa D. cv
Chandler) were grown in field plots and in drainage lysimeters
under controlled soil moisture regimes. Four irrigation
treatments were established by watering the plants when soil
water potential reached -0.01, -0.03, -0.05 and -0.07 MPa. The
maximum yield was attained at -0.01 MPa soil water potential.
Differences in yield were caused by both changes in the number
of fruits per plant and in the fresh weight per fruit. Yield
reductions were associated with reductions in total
assimilation rate resulting from the decreased assimilatory
surface area in plants irrigated at lower soil water
potentials. The crop water production function calculated on a
fruit fresh weight basis resulted in a yield response factor
(Ky) of 1.01.

Abstract: A general model of adoption of input-conserving
technologies by competitive firms is introduced using drip
irrigation as an example. An environmental regulation such as
a drainage effluent charge is shown to influence adoption.
Early adopters are likely to be producers with less efficient
fixed assets (land of low quality or antiquated capital),
higher input costs (higher water prices or greater depth to
groundwater), and in more environmentally sensitive regions.
Simulations show that drainage regulations can be expected to
play a major role in adoption of more efficient irrigation
technologies in California. Thus, conservation may be a key to
solving resource scarcity problems and reducing external
environmental costs.

Abstract: Procedures for analyzing the effects of
uncertainties on the on-farm time of application and applied
depth of irrigation have been presented using two parameter-
gamma densities for the different variables. The critical
coefficient of variation (CV) in delivered farm flow rate
beyond which variations in targeted depths cause more
deviations in time of application is found to be 0.25. For a
typical set of values for on-farm variables, reducing the CV
of farm flow below 0.12 does not improve the variance in
applied depth for the case of fixed CV values of 0.10 for farm
area and time of application. A distribution function for time
of application has been derived which will enable the
computation of reliable levels of application time. Solving
the yield problems considering the application system
hydraulics in a deterministic mode does not lead to large
errors when the variances in the on-farm variables do not
exceed 0.20. Generally, for shorter basins which are common in
many countries, higher efficiencies can be achieved.
Efficiencies less than 85% begin to occur when the length of
the basin exceeds 275 ft (84 m) for typical values of field
parameters in soils belonging to the Soil Conservation Service
infiltration family of 3.0.

Abstract: In the presence of conveyance losses, the efficient
quantity of water applied falls with distance from the water
source, but the amount of water "sent" (including conveyance
losses) actually increases with distance from the source,
except toward the tail end of the irrigation system. This
implies that if marginal cost pricing were implemented,
farmers at the middle and lower reaches of the system would
have to pay more money for less water received. The model is
illustrated and alternative financing schemes compared for an
empirically derived demand function for irrigation water.

Abstract: Most agricultural sprinkler irrigated acreage today
is under hand-move or motor driven systems. The present trend
is toward alternatives that are less labor intensive.
Permanent highly automated systems in which all components are
deeply buried are attractive because of the low labor use and
in the retraction mode the entire system is removed from
potential damage during tillage, harvesting, grazing of
livestock, or from vandalism. One unique system, AGRI-POP, in
which the riser and rotating sprinklers are completely
retractable and extensible was recently developed. Initial
field experience in this study exposed several design
problems. Correcting design flaws resulted in a fully
functional system. However, at an investment cost of about
$5,601/ha ($2,268/A) greater than the closest solid-set
alternative and about $7,000/ha ($2,835/A) greater than the
least expensive hand-line system, AGRI-POP presently is not an
economically viable alternative for most commercial
agricultural applications. Improved economics would result if
the system were mass produced and if relative costs of labor
increase. In addition, the system could be particularly useful
where strict environmental and water management controls are
desired. Several unique recreational and horticultural
applications are noted.

Abstract: Reducing irrigation volumes on turfgrass in an arid
environment requires close attention to environmental demand.
The objective of this research was to quantify the water
balances of three turfgrass sites controlled by an
evapotranspiration (ET) feedback system and local management.
Additional objectives included calculating leaching fractions
(LF), crop coefficients (Kc), water savings, and quantifying
the variability in potential evapotranspiration (ETo). A 2-yr
study was conducted on three turfgrass sites in southern
Nevada growing common bermudagrass [Cynodon dactylon (L.)
Pers.] overseeded with perennial ryegrass (Lolium perenne L.).
Two vacuum-drained lysimeters and one automated weather
station were placed at each location. One lysimeter was
irrigated by input from an ET feedback system while the other
was left to local management. The daily Penman combination
equation was used to calculate ETo. Hydrologic water balances
were maintained on each lysimeter on a weekly basis. A neutron
probe was used to measure changes in soil water content in the
lysimeters. Actual ET (ETa.) varied according to management,
with the two golf courses having an average ETa 29% higher
than the park site. Differences in ETa between the park site
and golf course sites were attributed to cultural management,
in particular fertilizer input. Crop coefficients varied on a
monthly basis and between high management vs low management
turf. A 4 to 6% error was observed in estimating ETo among the
three sites.

Abstract: Graded furrow applications of 100 to 200 mm (4 to 8
in.), which often exceed profile storage capacity, are common
in the Southern High Plains for the first irrigation after
primary tillage. This study evaluated furrow compaction by
wheel traffic as a potentially low cost method of reducing
excessive intake and conserving irrigation water. A two-year
field study was conducted with irrigated grain sorghum on a
slowly permeable Pullman clay loam (Torrertic Paleustoll). The
objective was to determine the effects of furrow compaction by
controlled wheel traffic on irrigation intake during the
preplant irrigation following primary tillage. In addition,
the effects of furrow ripping, before the second irrigation,
were compared with the non-traffic control furrows as a means
of restoring normal late-season intake. On relatively wide 1.5
m (5 ft) spaced furrows with a 0.15% slope, one traffic pass
with a 6000 kg (13,200 lb) tractor increased average bulk
density from 1.1 to 1.27 Mg/m3 at the 50 mm (2 in.) depth.
Furrow traffic reduced irrigation water advance time up to 45%
to reach 400 m (1320 ft), and reduced total intake by about
17% during the first irrigation after tillage. Ripping traffic
furrows before the second irrigation increased growing season
irrigation intake by 10% compared with the non-traffic
furrows. Controlled furrow traffic reduced average growing
season irrigation water intake by 12%. Furrow traffic and
furrow ripping treatments did not significantly affect grain
sorghum yield.

Abstract: Buffalo gourd (Cucurbita foetidissima HBK) and
coyote gourd (Cucurbita digitata Gray) are xerophytic
perennial cucurbits with potential as oilseed or starch crops
for arid and semiarid lands. This study investigated
irrigation and plant spacing effects on growth, water
requirements, and oilseed production of these species.
Irrigation of first-season buffalo gourds planted in 1981 at a
610-m elevation site on Pima clay loam [fine-silty, mixed
(calcareous) thermic typic Torrifluvent], and irrigation and
plant spacing were evaluated on first-season buffalo and
coyote gourds at a 360-m site in 1983 on Casa Grande sandy
loam (fine-loamy, mixed, hyperthermic Typic Natrargid) and
Trix clay-clay loam [fine-loamy, mixed (calcareous),
hyperthermic Typic Torrifluvent], respectively. Irrigation and
plant spacing were evaluated on second-season buffalo gourds
planted in 1983. Irrigation did not affect first-season
buffalo gourd yields. Second-season yields were reduced by
irrigating when the available soil water was 75% depleted (I2)
compared to irrigating when soil water was 50% depleted (I1).
Coyote gourd yields were reduced by the I2 treatment in 1983
but not in 1984. Consumptive water use for first season
buffalo gourds in the I1 treatment at the 610- and 360-m sites
was 870 and 645 mm, respectively. Consumptive water use was
similar for coyote and buffalo gourds at the 360-m site. In
the first season, these species derived up to 50% of water
used from the top 0.4 m of soil, and extracted water to a
depth of at least 2.6 m. Irrigation did not affect water-use
efficiency (WUE) of either species. Buffalo gourds had higher
WUE in the second season (0.09 kg seed m.3 water) than the
first season (0.04 kg m.3). Plant spacings of 0.25 to 2 m in
1-m spaced rows had no effect on first-season yield in 1983
but in 1984 a quadratic relationship indicated that the
closest and widest spacings reduced yields. Coyote gourd
cosistently out-yielded buffalo gourd at the 360-m site.

Abstract: The buffalo gourd (Cucurbita foetidissima HBK) is a
possible new root starch crop for semiarid regions.
Information on water use relationships of this species is
needed to determine its suitability for arid lands
agriculture. The objective of this study was to assess the
influence of water management on buffalo gourd tap root
production and water use. Five irrigation levels were
evaluated for an annual buffalo gourd crop in 1985 and 1986 at
a 360-m elevation field site on Casa Grande sandy loam (fine-
loamy, mixed, hyperthermic Typic Natrargid) using plant
populations of 400 000 to 450 000 plants ha-1. Irrigating at
50% available soil water (ASW) content (I1) gave higher fresh
tap root yields than irrigating at 75% ASW (I2) (27.8 vs. 24.1
Mg ha-1) in 1985 with identical starch yields. In 1986 the I2
treatment was higher than the I1 treatment in starch yield
(3.1 vs. 2.1 Mg ha-1) and tap root starch concentration (47.5
vs. 38.1%). Vines of water stressed plants (I2) grew rapidly
when irrigated. Consumptive water use was 649 and 487 mm in I1
and I2, respectively. Peak consumptive use rates were less
than 6.5 mm d-1. As much as 48% of seasonal water use was from
the 0 to 0.4 m soil depth. Water was extracted to a depth of
2.6m. The I2 treatment had the highest water-use efficiency
(WUE), 4.9 kg m-3, for fresh root production. The WUE for
starch production was higher for the I2 treatment (0.62KG m-3)
than the I1 treatment (0.42 kg m-3). Irrigation scheduling to
provide moderate stress reduces buffalo gourd water use
without reducing starch yield, increasing its potential as a
semiarid starch crop.

Abstract: Little research has been reported which quantifies
the response of a carrot (Daucus carrota L. var sativa DC.)
seed crop to water management. While the area of seed
production of this crop in the United States is less than 3
000 ha, the return ranges from US $2 000 to $10 000 ha-1.
Because of the need to mature and dry the seed on the plant,
carrot seed is generally grown in areas with negligible summer
rain and thus depends on irrigation to supply the crop water
requirement. A study was conducted to determine the effect of
irrigation water management on seed production and crop water
use of carrots grown by the root-to-seed method. Two carrot
types (Nantes and Imperator) were evaluated in 9 irrigation
treatments over a three year study period. Irrigation
treatments which replaced a percentage of the calculated crop
evapotranspiration on either a daily basis or when a soil
water depletion reached 30 mm were used. A trickle irrigation
system with the laterals placed on the carrot bed was used to
apply a uniform and accurate amount of water. There was a
marked difference in the crop response to the water management
of the two carrot types used. The Nantes type exhibited a
positive response to moderate water deficits in terms of
improved pure live seed (PLS) yield while the Imperator
achieved its maximum yield when it was not stressed. Higher
irrigation applications in the Nantes type resulted in reduced
yields while the Imperator was not affected after its non-
stress water requirement was met. Soil water data indicated
that the most active zone of extraction of water was to a
depth of 1.5 m in the soil profile. As the depth of applied
water approached the crop water requirement, the depth of
extraction was reduced. Increasing the frequency of irrigation
also tended to reduce the depth of extraction of soil water. A
total crop water use of approximately 550 to 620 mm was needed
to achieve the best PLS yield which is roughly equal to
potential evapotranspiration in th

Abstract: Agricultural land use in much of the Texas Coastal
Prairie consists of 1 yr of rice (Oryza sativa L.) followed by
2 to 4 yr of native pasture. Replacing some of the native
pasture with a cultivated rotational crop could benefit the
area's agricultural base by reducing fixed costs and aiding
pest management. Soybean [Glycine max (L.) Merr.] fits the
crop rotation system well but yields are highly variable and
marginally economical. Research was initiated in 1985 near
Eagle Lake, TX, to evaluate the potential of a nonionic
surfactant and supplemental irrigation to increase and
stabilize soybean yields on the Nada soil (fine loamy,
silicous, hyperthermic Typic Albaqualf). In addition the
effect of the surfactant and irrigation on P and K fertilizer
efficiency was evaluated. The nonionic surfactant (Amway ASPA
80, Amway Corp., Ada, MI) was injected through a lateral-move
irrigation system at 0.00, 0.36, 0.71, and 1.42 L ha-1 during
a 7 mm irrigation. Adjuvant rate, repeated adjuvant
applications within 1 yr and over 3 yr, and P and K at the
recommended and half the recommended rates were evaluated.
Supplemental irrigation was applied so irrigation plus
rainfall equalled 19 mm wk-1. No measurable yield differences
between P and K rates were detected. The
