 Simulation models
 
 Abstract:  Estimating the size of the ponded surface area is a
 major source of error in modeling water movement under tickle
 irrigation. After reviewing available approaches and models for
 simulating water flow under trickle irrigation, we present a new
 numerical solution of the governing partial differential equations
 that improves the prediction of the size of the ponded area at the
 soil surface. A common formulation could be used for both Cartesian
 and axicylindrical flow geometries. The spatial operator was
 approximated using finite differences, and time integration was
 performed with an implicit method. Nonlinearity was treated by
 means of a fixed point iterative algorithm. The proposed model is
 applicable to saturated-unsaturated flow in layered soils having
 anisotropic hydraulic properties. Accuracy and stability of the
 solution are checked and comparisons made with previous numerical
 solutions for several trickle irrigation and other unsaturated flow
 problems.

 Prediction
 
 Abstract:  A numerical solution for predicting soil water content
 distributions during trickle irrigation on stratified and
 anisotropic soils was compared with data from a field experiment
 carried out on a loamy clay soil using 24 field plots irrigated at
 different rates and frequencies. The unsaturated hydraulic
 conductivity was estimated from measured soil water retention and
 saturated hydraulic conductivities. Observed volumetric soil water
 contents and saturated areas on the soil surface were compared with
 model predictions. The effects of anisotropy and soil surface
 crusting on experimental and calculated soil water distributions
 were also investigated. Relatively good agreement was obtained
 between predicted and measured soil water content distributions vs.
 depth. The shape of the observed wetted soil volume was also
 predicted reasonably well. The effects of possible errors in the
 hydraulic characteristics on calculated water content
 distributions are discussed.

 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

 Abstract:  Multivariable experiments involving different water
 salinities are usually conducted using drip irrigation. Preparing
 the irrigation system to apply these different treatments requires
 a considerable investment of labor and materials. This study was
 conducted to examine an alternative irrigation system that is
 relatively simple and inexpensive, yet produces gradients of two
 variables. A variation of the line-source irrigation system was
 tested using water salinity and N levels as variables. The middle
 line of a triple line-source irrigated using saline water (7.0 dS
 m-1), while the two parallel outside lines irrigated using
 nonsaline water (1.0 dS m-1). A second triple line-source using
 only nonsaline water was superimposed perpendicularly on the first
 set. Ammonium nitrate was injected into the middle line. This
 layout produced linear gradients for both variables (r2 = 0.99)
 perpendicular to their source and provided every possible
 combination of saline water concentrations (7.0-1.0 dS m-1) and N
 levels (8.1-0.0 mmol L-1). It proved to be a simple yet highly
 informative system.

 Abstract:  This project was conducted on the Bell farm located in
 Pierce County, GA on Pelham loamy sand soil. The study area
 included 40 ha of land under controlled drainage-subirrigation (CD-
 SI) system of which 38 ha were in blueberries. The system
 installation included two drain spacings of 15.3 and 20 m, and two
 types of control structures for the drainage system outlet water
 level, which were an open ditch and a closed conduit system
 network. The blueberry section of the field was in a closed conduit
 system network with lateral drains spaced at 15.3 m. Seventeen
 punch-tape recorders were used to measure the water table
 elevations in the soil profile within the field over the drain
 tiles, and midway between drainlines, at the open ditch and closed
 system control structures (one for each), and in an undrained-
 nonirrigated section of the farm. A punch-tape rainfall recorder
 was also used to measure rainfall at the site. Surface runoff,
 drainage effluent, or subirrigation volume was not measured.
 Experimental results showed that the water table and soil-water
 conditions could be adequately managed in the blueberry field, thus
 excellent crop growth and yield resulted. DRAINMOD, a water
 management model for shallow water table conditions, was used to
 simulate the system performance for the study site. Simulation
 results indicated that a subsurface drain spacing of 20 m is
 satisfactory for controlled drainage-subirrigation (CD-SI) systems
 for Pelham loamy sand soils in Pierce County, GA. Simulations were
 done using 20 years of climatological data from Augusta, GA.
 Additional research is needed to develop specific design guides for
 other soil types in the Georgia Flatwoods region.

 Environmental policy; Pollution; Profitability; Simulation models
 
 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:  New Jersey 'Syn 4' asparagus (Asparagus officinalis, L.)
 was grown on a sandy loam soil to compare plant survival and yield
 of asparagus grown from crowns and transplants under four
 irrigation treatments: sprinkler (SPR), surface trickle (ST),
 subsurface trickle (SST), and no irrigation (NI). While plant
 survival of crowns was not appreciably influenced by any irrigation
 treatment, survival of transplants was significantly increased by
 SST. Total and marketable yields from crowns and transplants were
 similar in the first harvest season (year 3). However, in years 4
 and 5, the yield of crowns was higher than that of transplants.
 Subsurface trickle increased yield from transplants in years 4 and
 5 and increased yield from crowns in year 5. All irrigation methods
 significantly increased both spear production (spear/ha) and
 average spear weight. Subsurface trickle irrigation resulted in the
 largest increase over NI in total yield and spear production.

 Abstract:  Tomatoes (Lycopersicon esculentum Mill.) were grown on
 polyethylene-mulched beds of an Arrendondo fine sand during two
 seasons to evaluate the effects of trickle irrigation-applied N
 and/or K, percentages of trickle-applied nutrient(s) (50%, 75%, and
 100%), and schedules of nutrient application (variable, 2% to 12.5%
 of total amount weekly, or constant, 8.3% of the total amount
 weekly) on the occurrence of fruit external and internal blotchy
 ripening and fruit mineral nutrient concentration.
 Trickle-applied fertilizer was injected into the irrigation water
 weekly during the first 12 weeks of each season. External and
 internal blotchy ripening were less severe with trickle-applied N
 supplied as N + K or N than with preplant-applied N. Trickle-
 applied N + K or N resulted in higher fruit concentrations of N, P,
 K, Ca, and Mg than with all preplant-applied N. Internal fruit
 quality improved slightly as the trickle-applied percentage of N
 and/or K increased from 50% to 100%, but significant differences in
 exterior quality were not obtained. Internal fruit quality was
 higher early in the season than late in the season during both
 years, but this response was not associated with fruit elemental
 concentration. The weekly schedule of nutrient injection had no
 significant effect on fruit quality or fruit elemental
 concentration. Highest yields of high-quality fruit were obtained
 with 50% trickle-applied N + K.

 Abstract:  Surge flow irrigation was developed, in part, to take
 advantage of the property of some soils whereby irrigation water is
 more evenly distributed along the field by applying the water in
 "surges" (on and off cycles) instead of continuously. Thus, if
 water advances more during the second on-time of irrigation than
 the first, there must be some change in soil properties during the
 previous off-time. Three soils were used in this study: Nibley
 silty clay loam (a fine, mixed, mesic Aquic Argiustoll), Millville
 silt loam (a coarse-silty, carbonatic, mesic Typic Haploxeroll),
 and Kidman sandy loam (a coarse-loamy, mixed, mesic Calcic
 Haploxeroll). It was demonstrated by field experiments that the
 soil surface of the coarse and medium-textured soils consolidated
 markedly (soil surface elevation decreased about 3 mm) with surge
 compared to continuous water application for the first irrigation
 following spring tillage. The saturated hydraulic conductivity
 (Ksat) of these soils decreased about 45% from the first to the
 second on-time. The surge effect was more pronounced during the
 first than the second irrigation. Most of the effect measured
 occurred during the first 10 to 20 min of the first off-time.
 Consolidation and Ksat of the fine-textured soil was not changed
 significantly by the same treatment. Two simple and practical field
 methods to evaluate this surge effect on soil hydraulic properties
 were developed: (i) measurement of soil-surface consolidation by
 measuring the soil-surface elevation changes, and (ii) measurement
 of Ksat by the dripper method. The soil surface level decreased by
 more than 1 mm and Ksat changed by about 25% when the surge effect
 was significant. An infiltration model developed during this study
 showed that simulated cumulative infiltration for surge water
 application was similar to measured results for the three soils
 studied.

 Abstract:  Fruit and vegetative growth of 21-year-old grapefruit
 (Citrus paradisi Macf.) trees on well-drained sandy soil was
 studied in central Florida. Drip, microsprinkler, and overhead
 sprinkler irrigation was compared at two levels of irrigation (150
 and 450 mm.year-1). Significant differences in leaf area, fruit
 size, fruit growth, new flush growth, and canopy area were found
 with different irrigation systems applying similar amounts of
 water. Growth was improved by irrigation even in a year of high
 rainfall (1410 mm). With mature trees, drip systems promoted the
 least growth, while overhead sprinkler systems promoted the most.
 Leaf fresh and dry weights and individual leaf areas in the
 overhead sprinkler treatments were 40% to 50% greater than in the
 drip or nonirrigated treatments, while specific leaf weight and
 leaf water content per unit dry weight were similar for all
 treatments. Final fruit size and tree canopy area were 9% to 20%
 greater in the overhead sprinkler treatments than in the
 corresponding drip or nonirrigated
 treatments.  Responses to microsprinklers were generally
 intermediate between the overhead sprinkler and the drip
 treatments. Because of the low soil area coverage, applying water
 at the higher rate with the drip system did not improve growth as
 well as the overhead system at the lower rate. With mature
 grapefruit trees under central Florida conditions, systems
 providing greater soil area coverage gave better leaf and fruit
 growth than systems providing less soil coverage.

 Abstract:  'Tifbluc' and 'Delite' rabbiteye blueberry (Vaccinium
 ashei Reade) plants were grown for 4 years with or without mulch,
 with cultivated or sodded row middles, and under various irrigation
 treatments [one drip emitter at the base of the plant, two drip
 emitters 46 cm on either side of the plant, or a 40 degrees or 360
 degrees low-volume spray emitter (LVSE) place midway between
 plants]. Plant establishment and growth were optimal with 360
 degrees LVSE. Differences between irrigation treatments were
 minimized with mulch. Mulch increased growth of drip-irrigated but
 not of LVSE-irrigated plants and increased the yield of two-emitter
 and 360 degrees LVSE-irrigated plants but not of one-emitter or 40
 degrees LVSE-irrigated plants. Treatment effects on growth were
 more apparent in the early establishment phase than in the 4th year
 of growth and with 'Tifblue' than 'Delite'. Frost damage on
 'Delite' was reduced by mulch. Vegetative bud development in the
 spring and fruit maturity were usually delayed on plants grown
 between sodded alleys or with mulch. Leaf drop in the fall was also
 delayed by mulch.

 Abstract:  Studies were conducted to evaluate growth of tomato
 (Lycopersicon esculentum Mill.) transplants in the field in
 response to age of transplants in Spring and Fall 1989. Transplants
 were 2 (2W), 3 (3W), 4 (4W), 5 (5W), or 6 (6W) weeks old. Drip and
 subseepage irrigation were used. In spring, older transplants
 produced more shoot and root growth up to 2 (T2) weeks after
 transplanting. At 3 (T3) and 4 (T4) weeks after transplanting,
 there were no differences between 4W, 5W, and 6W transplants. These
 trends were independent of irrigation systems. Total yield and
 early yield were similar for all transplant ages. In fall, shoot
 growth increased linearly with increasing transplant age at T0, but
 not thereafter. Chlorophyll a + b increased over time, but no
 treatment differences were found at T4. At planting, 2W transplants
 had a higher Chl a:b ratio than older transplants. This difference
 was reduced at T1 and T2 and became insignificant at T4. These
 results indicate that no improvement in yields was obtained using
 the traditional older transplants. Younger transplants might be
 used to achieve rapid seedling establishment with minimal
 transplant production costs.

 time (5 min/day) or on soil moisture tensions of -1.5, -3.5, -7.5,
 and -15 kPa. Soil moisture tensions of -7.5 or -15 kPa caused
 significant reductions over the time-based treatment in fresh and
 dry weights of leaves, stems, and inflorescences and total leaf
 area, but had no influence on inflorescence diameter or cropping
 time. Stem length was reduced in those plants exposed to the two
 higher tensions; however, the resulting cut flowers were still long
 enough to satisfy commercial demands. The amount of water applied
 in tension-based treatments was 8% to 24% that applied in the time-
 based treatment. The -1.5-and -3.5-kPa treatments were best suited
 for minimizing water use while maintaining high crop productivity.

 Abstract:  Peppers (Capsicum annuum) were grown in three fields in
 which main plots were irrigated either on a more frequent or less
 frequent basis. Soil in subplots was left uninfested or was
 infested 5-6 wk after transplanting with one of three inoculum
 densities of Phytophthora capsici. In the Clayton field in 1988,
 where rainfall was low (16 cm), disease onset occurred 26 days
 after infestation in plots that were drip irrigated more
 frequently, whereas disease onset occurred 39 days after
 infestation in plots that were drip irrigated less frequently.
 Final disease incidence, the rate of disease increase, and mean
 area under the disease progress curve (AUDPC) values were
 significantly greater in infested plots irrigated on the more
 frequent than the less frequent schedule. More rainfall occurred at
 the Clinton and Clayton fields in 1988 and 1989, respectively (31
 and 22 cm), than at the Clayton field in 1988. Disease in plants in
 the higher rainfall fields progressed rapidly at all inoculum
 densities after a single rainfall >2.0 cm, and onset was earlier
 (5-7 days after infestation) than at the low rainfall field. Final
 disease incidence was independent of the density of inoculum
 applied at all three locations. However, inoculum density and
 rainfall had significant linear effects on the mean AUDPC values
 and yield. Mean AUDPC from the three field locations were 24.4,
 68.2, and 60.9%-days per day and mean yields were 10.4, 2.3, and
 2.1 kg/plot in fields receiving 16, 22, and 31 cm of total
 rainfall, respectively. Irrigation also increased mean AUDPC values
 significantly when means were calculated over all locations. Mean
 AUDPC values were 57.5%-days per day in plots irrigated more
 frequently and 44.8%-days per day in plots irrigated less
 frequently. Irrigation increased disease progress to the greatest
 extent in the low rainfall field in Clayton in 1988. The cumulative
 centimeters of rainfall between infestation of plots and the final
 disease assessment was correlated negatively.

 Abstract:  Cucumber (Cucumis sativus L. cv. Fidelio) grown in sand
 culture in the greenhouse was trickle-irrigated with nutrient
 solution containing 0, 10, or 50 mm NaCl. Gas exchange of
 individual leaves was measured by a portable infrared gas analyzer
 at saturating photosynthetic photon flux. Salt at 10 mm had no
 detectable effect on plant performance, but exposure to 50 mm NaCl
 caused net CO2 fixation to decline by 33% and 48% in the eighth and
 ninth oldest leaves, respectively. Stomatal conductance and
 transpiration rate were also reduced (approximately 50%) in these
 leaves. These differences, as well as lower leaf water potentials,
 were associated with a 60% reduction in fruit fresh weight. The
 relationship between net CO2 fixation and intercellular
 (substomatal) CO2 concentrations was determined for individual,
 attached leaves of plants with roots exposed to various
 concentrations of NaCl in hydroponics. With 50 and 100 mm NaCl, a
 nonstomatal contribution to the inhibition of photosynthesis at the
 chloroplast level was indicated by strong inhibition of CO2
 fixation at a saturating CO2 concentration. Salt-induced inhibition
 of CO2 fixation was associated with accumulation of Na+ and Cl-,
 and lower K+ in the individual leaves examined.

 Abstract:  Peanut (Arachis hypogaea L.), irrigated only recently in
 the coastal plain region of Virginia and North Carolina, is
 produced in an area where sodic deep water sources are more readily
 available than high quality shallow water sources. The objective of
 this work was to determine the effect of irrigation water qualtiy
 and irrigation method on the yield and grade of peanut. Virginia-
 type peanuts (cv. VA 81B) were grown on a Kenansville loamy sand
 (loamy, siliceous, thermic Arenic Hapludult) in Suffolk, VA from
 1984 to 1987. Peanuts were irrigated with either overhead
 sprinklers or deep buried trickle lines using deep-well (142 m) and
 shallow-well (10 m) water. Trickle lines were buried 350 to 410 mm
 below each row. Deep-well water had 220 mg Na L-1, a pH of 8.5, and
 a sodium adsorption ratio (SAR) of 103. Shallow-well water had 4.8
 mg Na L-1, a pH of 4.8, and an SAR of 3.1.  Shallow-well, trickle-
 irrigated peanuts yielded 5003 kg ha-1 or 14% higher than the
 nonirrigated treatment. Deep-well, sprinkler-irrigated peanuts
 averaged 4374 kg ha-1 for 4 yr, which was 21 kg ha-1 lower than the
 nonirrigated treatment. The price of deep-well, sprinkler-irrigated
 peanuts was also lower than all other treatments due to lower
 percentages of extra-large kernels, total sound mature kernels, and
 fancy pods. Deep-well water applied below 300 mm through trickle
 irrigation produced peanuts of comparable quality and quantity as
 the shallow-well, trickle, or sprinkler-irrigation treatments. 
 Irrigation of peanuts was beneficial in this humid region. There
 was no difference in peanut yield or grade when sprinkler or
 trickle irrigation was used with good quality irrigation water, but
 trickle irrigation required only 44% as much water. With a sodic
 water source, trickle irrigation was superior to sprinkler
 application.

 Modeling water table response to subirrigation and drainage.

 Abstract:  Conventional theory for predicting water table response
 to drainage and subirrigation generally assumes that the water
 table elevation directly over the drain is equal to the pressure
 head in the drain. This is contrary to field measurements which
 show head losses near the drain may be significant. Numerical
 methods were used in this study to solve the Boussinesq equation
 subject to radial flow conditions near the drain. Solutions were
 obtained for both drainage and subirrigation. Solutions showed that
 head losses near the drain make up a relatively large percentage of
 the total head loss for subirrigation with narrow drain spacings.
 As a percentage of the total, the radial head loss near the drain
 increases with increasing hydraulic conductivity and profile depth,
 and with decreasing drain spacing. This partially explains
 differences between relatively flat water table profiles measured
 in the field and steeper profiles predicted by previous theory. 
 Results showed that use of the conventional "Hooghoudt equivalent
 depth" method of correcting for convergence near the drain may lead
 to significant errors in predicted water table elevations and flow
 rates for subirrigation.  The methods presented also provide a
 means of correcting for convergence head losses when the drain
 rests on the impermeable layer.

 Abstract:  Studies were conducted to determine the effect of N
 application frequency through drip irrigation on soil NO3-N
 movement in the bed profile and on yield and N uptake by tomato
 plants (Lycopersicon esculentum Mill. 'Sunny') at two locations.
 increasing N application frequency resulted in increased yields at
 Clayton, N.C., but not at Charleston, S.C. The number of fruit
 produced was not affected by N treatment at either location, but
 fruit size increased with increasing N application frequency at
 Clayton. Foliage N concentration decreased seasonally, but neither
 foliage N concentration nor total N content of the above-ground
 portion of the plants was affected by N application frequency.
 Regardless of N application frequency, NO3-N concentrations within
 the raised bed decreased with time due to plant uptake and
 leaching. Nitrogen levels declined most rapidly in the area closest
 to the drip tube.

 Abstract:  The effects of six applied N treatments differing by
 rates and frequencies of application on the yield and quality of
 pepper (Capsicum annuum var. annuum L. 'Anaheim Chili') grown for
 seed was studied. The timing of N applications was based on crop
 phenology, leaf petiole nitrate-nitrogen concentrations (NO3-N)
 minimum thresholds, and scheduled calendar applications of fixed
 amounts of N. Solubilized NH4NO3 was applied through a trickle-
 irrigation system to ensure uniform and timely applications of N.
 Rate of mature (green and red) fruit production was unaffected by
 any treatment except weekly applications of 28 kg.ha-1 of N, which
 stopped production of mature fruit before all other treatments.
 Early season floral bud and flower production increased with
 increasing amounts of N. The two highest total N treatments
 produced more floral buds and flowers late in the season than the
 other treatments. Total fruit production was maximized at 240 kg
 N/ha.  Differences in total fruit production due to frequency of N
 application resulted at the highest total N level. Red fruit
 production tended to be maximized with total seasonal applied N
 levels of 240 kg.ha-1 and below, although weekly applications of N
 reduced production. Total seed yield was a function of red fruit
 production. Pure-live seed (PLS) production was a function of total
 seed production. Nitrogen use efficiency (NUE) for red fruit
 production also decreased with N rates >240 kg.ha-1, but PLS yield
 and NUE decreased in a near-linear fashion as the amount of total
 seasonal applied N increased, regardless of application frequency.
 Season average NO3-N (AVE NO3-N) values >4500 mg.kg-1 had total
 seed and PLS yields less than those treatments <4000 mg.kg-1. Six-
 day germination percentage was reduced with weekly N applications
 of 14 kg.ha-1. Seed mass was reduced with weekly N applications of
 28 kg.ha-1. Final germination percent, seedling root length and
 weight, and field emergence were unaffected by any of the N
 treatments.

 Abstract:  'Macspur McIntosh' and 'Red Chief Delicious' apple
 (Malus domestica Borkh.) on M.7a rootstock were subjected to
 treatments involving all combinations of two types of irrigation
 water (well-water or municipal effluent) from 1983, the year of
 planting, through 1987 and three rates of N fertilization (0, 200,
 400 g NH4NO3/tree per year), from 1984 through 1987. The zero N
 treatment was increased to 100 g NH4NO3/tree per year in 1986 due
 to low vigor of these trees. Effluent irrigation increased leaf N,
 P, and K concentration in 4 of 5 years for 'McIntosh', while leaf
 N, P, and K increased in 1, 4, and 2 years, respectively, for
 'Delicious'. Effluent irrigation increased trunk diameter increment
 in all years and fruit number and yield in 1985-86 for both
 cultivars. No major horticultural limitations to the use of
 effluent irrigation were observed. Nitrogen fertilization increased
 leaf N in 3 years for 'McIntosh' and 2 years for 'Delicious', while
 leaf P and K were decreased at the highest N rate in 2 years for
 each cultivar. Nitrogen fertilization did not increase trunk
 diameter and increased fruit number and yield only in 1986 after 3
 years of a zero N treatment. The results implied a role for P in
 the establishment and early growth and yield of young apple trees.

 Abstract:  The determination of the considerable amount of water
 used in south Florida for crop production has been time-consuming
 and expensive. The Standard Class A National Weather Service pan
 evaporation (SPE) has been used to estimate evapotranspiration
 (ET), but requires crop coefficients, ET/SPE, which vary with plant
 development stage, season, leaf area index (LAI), yield, and
 irrigation method. The objective of this study was to establish
 relationships among ET, SPE, LAI, yield of plant and two ratoon
 crops of sugarcane (Saccharum spp.), and two irrigation methods.
 Lysimeters were used for 3 yr (1980-1982) on a Boca fine sand
 (loamy, siliceous, hyperthermic Arenic Ochraqualfs). Irrigation
 methods were drip irrigation and subirrigation systems. Total crop
 seasonal ET values were 1322 mm for drip irrigation, and 1275 mm
 for subirrigation. The sugarcane average yield under drip
 irrigation (143 t/ha) was significantly higher than that under
 subirrigation (119 t/ha), and was linearly related to the ET. The
 crop coefficient is curvilinearly related to the LAI. The
 relationship of ET/SPE to LAI was: 0.649 + 0.185 LAI -0.025 LAI2
 (R2 = 0.77) for both irrigation methods. The relationship of ET/SPE
 to LAI of the second ratoon under subirrigation was: 0.599 + 0.089
 LAI - 0.011LAI2 (R2 = 0.87).

 Abstract:  We studied the horizontal and vertical root distribution
 of 3-year-old 'Climax' rabbiteye blueberry (Vaccinium ashei Reade)
 in a sandy loam soil. Root density decreased logarithmically in the
 horizontal direction from the crown and linearly with depth. Ninety
 percent of the roots were within 0 to 0.38 m from the crown and 0
 to 0.45 m depth. Roots spread more within the rows than across
 rows. Sawdust mulch increased the radial spread of roots, but did
 not promote rooting in the top 0.15 m of soil. Compared to one or
 two drip emitters per plants, low-volume spray emitters increased
 radial spread of roots, but only in combination with mulching.
 Greatest vertical rooting occurred with a single emitter at the
 base of the plant without mulch. Emitters placed 0.46 m from the
 crown of the plant did not help the spread of roots towards these
 emitters.

 Abstract:  Two trickle irrigation experiments were conducted during
 two successive years with cucumber (Cucumis sativus L.) and tomato
 (Lycopersicon esculentum Mill.) grown on a coarse-textured soil in
 ground beds in a greenhouse. Several trickle irrigation design
 characteristics (emitter spacings of 15, 30, and 45 cm and one or
 two laterals per crop row) and water management variables (2 or 8
 liters/hr per emitter water application rates and water quantities
 equivalent to 0.25- and 0.50-times pan evaporation) were examined
 for their effect on soil water content, root distribution, and
 plant water status. Water application rates did not influence root
 density distributions or plant water status; however, the 8
 liters.hr-1 water application rate resulted in higher water content
 in the top 20 cm of soil than the lower application rate. The
 higher water quantity resulted in higher soil water content, higher
 root density, and improved plant water status than with the lower
 quantity. Mature plants had root systems that were well-adapted to
 the different soil water distributions. Only the amount of water
 applied influenced the water status of mature cucumber plants and
 cucumber fruit yields.

 Abstract:  Growth chamber evaluations of soil from an orchard
 replant site showed severe stunting of 'Northern Spy' apple (Malus
 domestica Borkh.) seedlings grown in field soil (FS) compared with
 pasteurized soil (PS) from the same site. The FS : PS seedling dry
 weight ratio of 0.44 indicated a serious replant problem. Leaf
 nutrient content was generally higher in PS than FS seedlings.
 Multiple-regression analysis indicated that leaf K and root-lesion
 nematode (Pratylenchus penetrans Filipjev) primary inoculum
 accounted for 75% of the variation in FS seedling dry weight. Apple
 seedling dry weight in FS was 97% of that in PS following a
 marigold (Tagetes patula L. cv. Sparky) cover crop, and 75%
 following oats (Avena sativa L. cv. Saia). Root-lesion nematodes
 were nearly eliminated from the plots with marigold. Other cover
 crops and weed-free fallow period were less effective in
 controlling apple replant disease and/or phytonematodes.

 Abstract:  Vegetables in Florida are often grown on plastic-mulched
 beds in sandy soils that commonly require irrigation even if they
 are subject to naturally occurring high water tables. Increasingly,
 these crops are being irrigated with line source drip irrigation
 systems. In this study, experiments were conducted in lysimeters to
 determine the redistribution and extraction patterns of a tomato
 crop under similar soil and irrigation management conditions. Soil
 water potential data were continuously collected using, a
 microcomputer-based, tensiometer-pressure transducer, data
 acquisition system. These data were used to develop soil water
 equipotential lines in the bedded soil profile, from which
 redistribution and extraction patterns were determined. The data
 indicated that very little change in soil water status took place
 at horizontal distances of more than 250 mm from the irrigation
 lateral and at depths greater than 300 mm, and that this is the
 region in which irrigations should be concentrated for this
 production and management system.

 Abstract:  High-frequency phosphorus fertigation may increase the
 time-average P concentration in the soil solution above that
 expected from P solubility considerations. Where P is a yield-
 limiting factor, frequent P fertigation may increase yield by
 stimulating P-uptake by the roots. A field experiment was conducted
 on a loessial soil (Haploxeralf) high in NaHCO3-extractable P (0.8
 mmol kg-1 soil) to test the hypothesis that subsurface placement of
 emitters (SSR) is more effective in stimulating P uptake than
 surface placement (SR). Four concentrations of P in the water (Cp),
 0.04, 0.16, 0.64, and 1.29 mol P m-3, were applied via surface or
 subsurface emitters to sweet corn [Zea mays (L.) Jubilee].
 Marketable ear yield increased with Cp, yielding 22.9, 24.3, 24.9
 and 28.9 t ha-1, respectively. Yield was higher for tricklers
 placed 30 cm below soil surface (25.2 t ha-1) than on the surface
 (23.5 t ha-1). Elevated Cp increased the soil solution P
 concentration, thereby increasing total P uptake and total dry
 matter production by the plants. Deep trickler placement
 significantly increased the fraction of total dry matter allocated
 to the ears, which resulted in higher marketable yield. Subsurface
 irrigation also reduced weed growth due to the dry top soil during
 the experiment.

 Abstract:  The objectives of this field study, conducted in 1984
 through 1986, were to assess the long-term effects of applying
 treated municipal effluent (ECw = 2.6 dS m-1. SAR = 12.0) by
 trickle irrigation on soil N fertility, soil salinity, and yield of
 cotton (Gossypium hirsutum L. cv. Sindos 1980) under semiarid
 conditions. Secondary treated effluent was compared with borehole
 water. Both waters were supplemented with 0, 30, 60, and 90 mg N
 L-1. The N concentration in the effluent was about 30 mg L-1 during
 the 3 yr of experimentation. The residual soil NO3-N and the NO3-N
 concentrations in laminae and petioles were in general greater in
 the effluent-irrigated crops. With both waters, excessive salt
 buildup occurred at the periphery of the wetting front. Sodium
 adsorption ratio (SAR) was reduced beneath the dripper in the
 surface 15 and 30 cm depth with borehole water and effluent,
 respectively, but below this depth the reverse occurred. Under the
 conditions of soil type, climate, and borehole water and effluent
 qualities used during this experiment, effluent was generally
 superior to borehole water, particularly at the lower N levels in
 increasing yields. The seedcotton yield obtained in the first
 season was significantly greater in the effluent irrigated
 treatments supplemented with N up to 60 mg L-1; in 1985 and
 1986seasons, yield with treated effluent was significantly higher
 in comparison with borehole water when additional N of 30 mg L-1
 was applied. It can be concluded that municipal-treated effluent
 containing 30 mg N L-1 can be used effectively by trickle
 irrigation systems as a source of irrigation water and N, and with
 appropriate N and water management, ecological hazards due in NO3-N
 are minimized, and salinity and sodicity are maintained at
 acceptable levels for cotton.

 Abstract:  Tomatoes (Lycopersicon esculentum Mill.) were grown
 during two seasons at two locations on fine sands and fine sandy
 loam soils to study the influence of water quantity, frequency of
 water application, and timing of N and K application for
 polyethylene-mulched, trickle-irrigated fresh-market tomatoes.
 Water quantities were 0.50 and 1.0 times pan evaporation applied
 one or three times daily. Nitrogen and K were applied 100% preplant
 or 40% applied preplant and 60% applied with trickle irrigation.
 Higher tomato leaf tissue N and K concentrations in one of the two
 seasons and higher fruit yields were obtained with 0.5 than with
 1.0 time pan water evaporation on a fine sand at Gainesville, Fla.
 On a fine sandy loam soil at Quincy, fruit yields were higher in a
 relatively dry season with the higher water quantity and not
 influenced by the water quantity applied in the second relatively
 wet season. The number of daily water applications (one vs. three)
 at both locations had no effect on N and K uptake or fruit yields.
 Time of N and K applications had no effect on early yields, but
 total yields were higher with split than all preplant-applied N and
 K on the fine sandy soil. Split applications of fertilizer resulted
 in greater yields of extra-large fruit at mid-season and of extra
 large fruit at late harvest than all preplant-applied fertilizer.
 On the fine sandy loam soil, time of fertilizer application had no
 effect on yield.

 Abstract:  Water relations responses of 21-year-old grapefruit
 trees (Citrus paradisi Macf.) irrigated by three types of
 irrigation systems were compared. Drip, undertree microsprinkler,
 and overhead sprinkler with application levels of 150 and 450 mm of
 water per year were compared. Leaf water potential, stomatal
 conductance, and soil water status were measured under field
 conditions on a deep, well-drained sandy soil in central Florida.
 In the early part of a dry spring period, there were no differences
 in midday or early morning leaf water potential, but, by the end of
 this period, significant differences in leaf water potential were
 found among all three irrigation treatments. Highest leaf water
 potential and stomatal conductance values were maintained in the
 overhead sprinkler blocks. No midday stomatal closure was observed
 under the conditions of this study. Relationships among diurnal
 leaf water potentials, vapor pressure deficits, and stomatal
 conductance showed hysteresis; this affected the correlations among
 these factors. Greater water stress occurred in trees irrigated
 with drip than in trees irrigated with overhead sprinkler systems,
 but responses to microsprinklers were generally intermediate
 between the overhead sprinkler and the drip treatments. In an area
 with high rainfall and sandy soils, increased irrigation coverage
 can reduce leaf water stress.

 water potential; Xylem water potential; Soil water balance;

 Abstract:  Several studies have shown that water can move through
 plant root systems from wet to dry soil during periods of low
 evaporative demand. It has been suggested that such movement could
 be important in alternate furrow or drip irrigation systems, where
 water is applied in a discrete or nonuniform manner. This study was
 undertaken to examine this question, using a physical experiment
 and computer simulation. A growth chamber experiment was conducted
 with three rows of cotton (Gossypium hirsutum L.) plants. The outer
 row plants were grown over vertical barriers such that half of
 their root systems shared a volume of soil with the center row
 plants, while the other half was hydraulically isolated in separate
 soil compartments. The center compartment was allowed to dry, while
 the outer compartments were watered daily. Soil moisture was
 measured throughout all compartments twice daily by gamma
 densitometry. When the potential gradient between center and outer
 compartments reached 1.0 MPa, the gamma readings showed overnight
 movement of water from wet to dry soil that could only have taken
 place through the root systems of the outer row plants. The
 overnight transfer of water, while significant, was not sufficient
 to fully supply the daytime transpiration demand of the unirrigated
 center row plants. It was also less than that predicted by computer
 simulation, unless the latter reflected the inability of the xylem
 water potential of cotton plants to equilibrate with soil water
 potential during periods of low evaporative demand. Regardless, the
 results suggest that water transfer by root systems should not be
 excluded in simulations of water movement in the soil-plant-
 atmosphere system.

 Abstract:  Yield of irrigated cotton (gossypium hirsutum L.)
 increases as the interval between water applications is decreased,
 even if the total amount of water applied is unchanged. Experiments
 were undertaken to compare season-long water relations of high-
 frequency drip-irrigated cotton (1- to 2-d intervals) to cotton
 irrigated at approximately 2-wk intervals. The crop was grown at
 two locations in central Arizona on a Mohall sandy loam (fine-
 loamy, mixed, hyperthermic Typic Haplargid) and an Avondale clay
 loam (fine-loamy, mixed, hyperthermic Typic Torrifluvent) soils. In
 2-yr trials at each location, irrigation frequency had inconsistent
 effects on midday leaf water potential during vegetative growth.
 When the crop developed a heavy fruit load, however, leaf water
 potential of plants on the longer cycles was much lower than that
 of drip-irrigated plants, even after irrigation when ample soil
 moisture should have been available. Plant hydraulic conductances,
 estimated from regressions of single-leaf transpiration rate
 against leaf water potential, were high in both treatments early in
 the season. Hydraulic conductance decreased greatly during fruiting
 in plants on long irrigation cycles but less so in drip-irrigated
 plants. Late in the season, after fruit maturation and during plant
 regrowth, conductances were again high and similar in the two
 treatments. The results imply that during heavy fruiting, mild
 water stress associated with long irrigation cycles triggers
 deterioration of the root system that is very slow to be reversed.
 High-frequency drip irrigation, by preventing cyclical stress,
 apparently minimized this deterioration during fruit filling.

 Abstract:  The impact energy of water droplets from rain or
 overhead sprinklers can cause a seal to form at the soil surface.
 This constitutes a severe problem in agricultural lands in the arid
 and semiarid regions. Spreading a soil conditioner on the surface
 of the soil and providing a constant supply of electrolytes may
 prevent seal formation. The effect of droplet impact energy and
 water quality on infiltration and erosion was studied, using a tank
 drip-type rain simulator, in a sandy loam soil (Typic Rhodoxeralf)
 treated with an anionic polyacrylamide (PAM) and phosphogypsum
 (PG). Three kinetic energies (KE) of 3-mm diameter drops were
 obtained by varying their falling heights. The two qualities of
 water were distilled water (DW) and tap water (TW), to simulate
 rain and irrigation water, respectively. Increasing the impact
 energy reduced the infiltration rate (IR), cumulative infiltration
 (rain intake), and soil erosion in all treatments. Addition of PAM
 in the presence of electrolytes (either PG or TW) increased both
 final IR and cumulative infiltration by 7- to 8-fold compared with
 the control, and was much more effective than PAM, PG, or TW alone.
 The PAM+ electrolyte treatments decreased soil erosion by more than
 one order of magnitude compared with the control.

 Abstract:  Field studies were conducted on a Typic Xerorthents
 Entiosols soil (Hanford sandy loam) to determine the response of
 two cultivars of processing tomatoes (Lycopersicon esculentum
 Mill.) to trickle irrigation applied at three percentages of
 evapotranspiration (ET) to either the top of the plant row or
 between the beds using a traveling irrigation system. Irrigation
 was terminated when fruits were either 30% or 70% red 14 or 7 days
 before harvest). Yields of red tomatoes and total tomatoes
 increased with increasing trickle irrigation water. The
 concentrations of soluble solids (SSC) and total solids (TS) and pH
 decreased with increasing trickle irrigation rates, while color,
 fruit size, and acidity increased, as did the yield of SSC and TS
 per hectare. Placement of trickle irrigation on the plant row was
 more favorable than placement in the furrow between the beds for
 yield and quality characteristics. Trickle irrigation to 70% ET
 terminated 7 days before harvest produced responses similar to
 conventional furrow irrigation. Although statistically these
 treatments could not he compared directly to conventional furrow,
 all traveling trickle irrigation rates were superior in water use
 efficiency to that of the conventional furrow irrigation. Trickle
 irrigation rates of 35% ET, 70% ET, and 105% ET did not differ in
 water use efficiency. Chemical names used: 2(a-naphthoxy)- N,N-
 diethyl propionamide (napropamide); S-propyl butylethiocarbamate
 pebulate).

 Abstract:  Production practices that increase hay yields are
 important for beef cattle producers in the Nebraska Sandhills. This
 study evaluated the responses of subirrigated meadow vegetation to
 fertilization with N, P, and S over a 4-yr period. A factorial
 array of four levels of N (0, 45, 90 and 135 kg ha-1), two levels
 of P (0 and 20 kg ha-1) and two levels of S (0 and 22 kg ha-1) were
 applied each year to the same plots, arranged in a randomized
 complete block design. Average dry matter yields were increased by
 N, P, and S. There were no fertilizer interaction effects. Yields
 increased quadratically as N levels increased. For each 45 kg
 increment of N applied from 0 to 135 kg ha-1, dry matter yield
 (pooled over P and S) increased 1002, 703, and 402 kg ha-1,
 respectively. Main effects of P and S increased dry matter yields
 by 4662 and 577 kg ha-1, respectively. Nitrogen uptake was
 increased linearly by fertilization with N, P, and S. Forage N use
 efficiency decreased as N fertilizer rates increased. Crude protein
 (CP) declined quadratically as N rates increased, but the maximum
 change was less than 10 g kg-1. In vitro dry matter digestibility
 (IVDMD) declined linearly as N rates increased. Sulfur and P did
 not affect either CP or IVDMD. Yield responses were sufficient to
 justify the use of N, P, and S to increase subirrigated meadow
 production. Less of forage quality (CP and IVDMD) was not
 sufficient to nullify this conclusion.

 Abstract:  Broccoli (Brassica oleracea L. var. italica), followed
 by tomato (Lycopersicon esculentum Mill.) or squash (Cucurbita pepo
 L. var. melopepo), and then broccoli were produced in succession
 re-using the same polyethylene-mulched beds at two locations with
 different soil types.  First-crop broccoli yield was earlier and
 greater with drip than with overhead irrigation and increased as N-
 K rate increased from 135-202 to 270-404 kg.ha-1. On a fine sandy
 soil, yields of second and third crops produced with residual or
 concurrent fertilization increased with an increase in N-K rate. 
 On a loamy fine sandy soil, yields also increased as the rate of
 residual N-K increased; yields of second and third crops did not
 respond to rate of concurrently applied N-K, but were higher with
 concurrent than with residual fertilization, except total tomato
 yields were similar with either application time. With drip
 irrigation and concurrent weekly fertigation, yields equalled or
 exceeded those obtained with preplant fertilization and overhead
 irrigation.

 Abstract:  Tomatoes (Lycopersicon esculentum Mill.) were grown on
 polyethylene-mulched beds of an Arredondo fine sand during two
 seasons to evaluate the effects of trickle-applied N and/or K,
 percentages of trickle-applied N and K (50%, 75%, and 100%), and
 schedules of N and K application on fruit yield, and leaf and shoot
 N and K concentrations. The daily irrigation requirement,
 calculated at 47% of the water evaporated from a U.S. Weather
 Service Class A pan (Epan), was met by the application of 4.6 mm to
 7.2 mm water/day. Fertilizer was injected weekly in a variable (2%
 to 12.5% of the total amount weekly) or constant (8.3% of the total
 amount weekly) schedule during the first 12 weeks of each season.
 Trickle-applied nutrients and trickle-applied percentage of
 nutrients interacted in their effects on early, midseason, and
 total marketable fruit yields. When N + K and N were trickle-
 applied, the mean early total marketable fruit yield decreased
 linearly from 25.3 t.ha-1 to 16.3 t.ha-1 as the trickle-applied
 percentage of nutrients increased from 50% to 100%; but when K was
 trickle-applied (100% preplant-applied N), yields were not affected
 by the trickle-applied percentage (mean 26.3 t.ha-1). The weekly
 schedule of N and K injection had no effect on fruit yield or other
 characteristics. Higher leaf N and K concentrations early in the
 season were obtained when the respective nutrient was 50% to 100%
 preplant-applied than when the respective nutrient was 75% to 100%
 trickle-applied; but late in the season, higher concentrations were
 obtained when the respective nutrient was trickle-applied. Higher
 yields, however, were associated with higher early season leaf N
 concentrations rather than with higher late-season leaf N or K
 concentrations.
