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.

A
bstract: 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 adjuvant at 0.36 L ha-1
increased soybean yields 37% above the check. Adjuvant at the 0.71 and 1.42 L
ha-1 rate decreased yield from the 0.36 L ha-1 rate. No phytotoxicity was
observed. Multiple adjuvant applications during 1 yr, and repeated applications
to the same area over years, had no additional beneficial yield effect.

Abstract: A model for the optimal operating policy of a reservoir for
irrigation under a multiple crops scenario using stochastic dynamic programming
(SDP) is developed. Intraseasonal periods smaller than the crop growth stage
durations form the decision intervals of the model to facilitate irrigation
decisions in real situations. Reservoir storage, inflow to the reservoir, and
the soil moisture in the irrigated area are treated as state variables. An
optimal allocation process is incorporated in the model to determine the
allocations to individual crops when a competition for water exists among them.
The model also serves as an irrigation scheduling model in that at any given
intraseason period it specifies whether irrigation is needed and, if it is, the
amount of irrigation to be applied to each crop. The impact on crop yield due
to water deficit and the effect of soil moisture dynamics on crop water
requirements are taken into account. A linear root growth of the crop is
assumed until the end of the vegetative stage, beyond which the root depth is
assumed to be constant. The applicability of the model is demonstrated through
a case study of an existing reservoir in India.

Abstract: Stochastic optimization of inputs in a spatially variable natural
resource is studied, with special emphasis placed on the problem faced by a
risk-averse decision maker (DM): how to use, in the best possible way, the
given body of information, which is embodied in one realization of the relevant
measurements. Two approaches, unconditional and conditional, are investigated
and compared. The unconditional and the conditional stochastic optimization
problems are defined and an illustrative numerical example is given. The
principal conclusion drawn is that the conditional analysis has the potential
to increase the DM's welfare substantially, as compared with the unconditional
one.

Abstract: The performance of LEPA equipment on a center pivot machine was
evaluated at three different radii at three different slopes. Application
uniformity was best at the outer end and poorest at the middle of the pivot
mainline pipe. No runoff occurred on 1% slope but excessive runoff occurred on
the 3% and 8% slopes. Simulations indicated performance could be improved by
constructing microbasins in the furrows.
