Quick Bibliography Series Bibliographies in the Quick Bibliography Series of the National Agricultural
Library, are intended primarily for current awareness, and as the title of the
series implies, are not indepth exhaustive bibliographies on any given subject.
However, the citations are a substantial resource for recent investigations on
a given topic. They also serve the purpose of bringing the literature of
agriculture to the interested user who, in many cases, could not access it by
any other means. The bibliographies are derived from computerized on-line
searches of the AGRICOLA data base. Timeliness of topic and evidence of
extensive interest are the selection criteria.
The author/searcher determines the purpose, length, and search strategy of the
Quick Bibliography. Information regarding these is available upon request from
the author/searcher.
Copies of this bibliography may be made or used for distribution without prior
approval. The inclusion or omission of a particular publication or citation

Abstract: Ladino clover (Trifolium repens L.) has traditionally been
established in the autumn in the southeastern USA. Grass suppression and
insect control have proven beneficial for successful autumn no-till
establishment. Winter planting offers an alternative, yet little is known about
late winter grass suppression and insect or mollusk control. Herbicide applied
at planting in late winter usually failed to suppress or kill
cool-season grasses. Field studies were conducted to evaluate (i) the
influence of fall suppression or kill with paraquat (1,1'-dimethyl-4-4'
bipyridinium ion) of the tall fescue (Festuca arundinacea Schreb.) sward on
late-winter (February or March) no-till establishment of ladino clover, (ii)
establishment by drilling versus surface planting and (iii) the influence of
suppression of insect and/or mollusk populations on the late-winter no-till
establishment of ladino clover into tall fescue. Initial late winter no-till
clover densities were 30% greater for the March as compared to February
planting (three experiment average). Drill planting of clover resulted in 2.1
times greater initial clover density (four experiment average) and 1.9 times
more clover yield than surface planting (three experiment average).
Application of paraquat to tall fescue in bands (13 cm) in mid-October
resulted in essentially complete grass kill with the bands. Neither autumn
grass suppression nor the use of insecticide or molluscicide altered clover
density or stand. Late-winter, no-till establishment provides an alternative to
fall establishment. Our results indicate that fall chemical suppression of
grass swards is not necessary for successful late-winter establishment of
ladino clover.

Abstract: Field plots of conservation-tillage wheat straw naturally infested
with Pyrenophora tritici-repentis were treated with bran-based inoculum of
three potential biocontrol fungi, and reduction in the number of residue-borne
pseudothecia (primary inoculum of the pathogen) was determined. Limonomyces
roseipellis significantly reduced residue-borne primary inoculum of P.
tritici-repentis in 3 of 4 yr of experiments; an unidentified agonomycete was
effective in two of three experiments, but Laetisaria arvalis was ineffective.
Although L. roseipellis reduced inoculum by 60-80%, greater reductions would be
necessary for acceptable control of this disease. Retention of dry
bran-based inoculum on straw was enhanced by the use of alginate, but further
improvements in formulation and application methods are required for effective
biocontrol of pathogens in surface-borne crop residues.

Abstract: Modern crop production creates a cycle between soil compaction
caused by traffic and alleviation of this condition by tillage or natural
processes such as freezing and thawing. The objective of this study was to
evaluate important management practices as they relate to changes in bulk
density of a tilled sandy loam soil. Practices evaluated were irrigation
method, time between tillage and traffic, tire pressure and wheel load of
applied traffic, and controlled traffic. Relationships among bulk density,
penetration resistance, and infiltration rate were determined. Experiments were
conducted in the San Joaquin Valley of California, on a sandy loam soil
(Entisol) with an organic-matter content of < 1%. After tillage, settling and
trafficking of a soil resulted in rapid changes in its bulk density until a new
equilibrium was reached. Tire pressure of 408 kPa and wheel weight of 2724 kg
applied at moisture contents near field capacity resulted in a bulk density of
1.92 Mg m-3, compared with a value of 1.67 for no traffic. The time
interval between tillage and traffic did not affect final bulk density. Drip
irrigation, which did not saturate the soil, resulted in a bulk density of
approximately 0.1 Mg m-3 lower than flood irrigation, which saturated the soil
surface. Wheel traffic in the furrow resulted in only small changes in the bulk
density within the row. When tillage did not occur between cropping
seasons, traffic caused high bulk densities in the furrow but only small
changes in the row. An increase in bulk density from 1.7 to 1.89 Mg m-3
decreased the infiltration rate by four times and increased resistance to
penetration at the end of the season by three times. Knowledge of how
management practices affect bulk density can aid growers in reducing
recompaction following tillage.

Abstract: Rye (Secale cereale L.) cover crops are often promoted to supply
additional residue in no-till production situations; however, the effect of
inclusion of rye on soil chemical properties is largely unknown. Soils were
sampled, 20 cm deep, from four 4-yr studies in which no-till corn (Zea mays L.)
and soybean (Glycine max L. Merr.) were grown continuously or in rotation on a
Canfield silt loam (fine-loamy, mixed, mesic Aquic Fragiudalf) or in rotation
only on a Hoytville silty clay (fine, illitic, mesic Mollic
Ochraqualf), with and without a winter rye cover crop. Corn had been
fertilized each spring with 224 kg N ha(-1) as either injected anhydrous
ammonia or surface-broadcast urea-ammonium nitrate (UAN) solution. All plots
sampled showed greater concentrations of organic C, exchangeable K, and Bray-1
extractable P in the surface 5-cm increment of soil than deeper in the sampled
profile. Exchangeable Ca and Mg concentrations were often less at this depth
than deeper in the profile, particularly when N was applied as
surface-broadcast UAN solution. Soil pH was generally lowest in the zone of N
application. Addition of the rye cover crop had little effect on the
distribution of chemical attributes, other than increasing concentrations of
exchangeable K near the soil surface in several comparisons.

Abstract: A comparison of defined-area traps (DATs) and refuge traps (RTs), in
no-till alfalfa (Medicago sativa L.) to census the slug species Deroceras
reticulatum (Muller), Deroceras laevae (Muller), and Arion fasciatus (Nielson)
was made. The objective of the study was to determine whether Rts could be used
in a range of crop densities and climatic conditions to assess slug
density. In relation to slug density measured by DATs, Rts were less effective
in trapping slugs in spring, when D. reticulatum was very small, but trapped
relatively higher numbers than DATs when slugs were larger. Trapping methods
were assessed between May and November in no-till alfalfa plots with plant
densities ranging from 52 to 99% total plant cover in May to 78 to 91% cover in
July. Alfalfa crop density had no effect upon RT catches except in dry
conditions in June, when Rts collected more slugs in plots with most
vegetation cover. Neither trap collected slugs during severe drought
conditions in July when soil moisture content in the top 5 cm of the soil
profile dropped to about 6%.

Abstract: Studies in Ontario have shown that corn (Zea mays L.) yields are
reduced when corn is seeded immediately after rye (Secale cereale L.) harvest
or chemical kill of winter rye. A study was conducted in 1983 and 1984 on a
Maryhill (Typic Hapludalf) loam soil to determine the effect of spring tillage
systems and timing of rye chemical kill on the subsequent corn crop. The rye
was seeded in early October after corn silage harvest. The tillage treatments
consisted of (i) moldboard plow plus secondary tillage, (ii) strip tillage,
(iii) no-tillage with ripple coulters (iv) no-tillage with disc furrowers plus
plow coulters, and (v) no-tillage with ripple coulters plus plow coulters. The
rye kill treatments were early (2 wk before planting) or late (just prior to
corn planting). Corn whole-plant yields averaged 13.6 and 12.4 Mg ha-1 for
early and late rye kill, respectively. Corn yield in the moldboard plow
treatment was higher thin in strip tillage and the average of no-till
treatments; however, using disc furrowers produced yields equal to those with
the moldboard plow treatment. Moving the residue out of the row with disc
furrowers resulted in corn yields that were significantly higher than those in
no-till treatments with ripple coulters. The improvement in plant growth due to
an early rye kill (as opposed to a late rye kill) was often greater with the
conservation tillage systems relative to the moldboard plow treatment. A crop
production system is proposed involving chemical control of a winter rye cover
crop 2 wk before corn planting and planting the corn with a modified no-till
system that removes rye residue from the row area.

Abstract: The use of monoculture production systems such as continuous corn
(Zea mays L.) in conservation-tillage systems has created a requirement for
information concerning crop and weed responses to annual herbicide inputs. The
objective of this 5-yr investigation (1981-1995) was to evaluate weed problems
and delineate weed and crop interactions in continuous conservation-tillage
corn as affected by annual herbicide applications. Preemergence treatments
contained selected combinations of triazines or a triazine plus alachlor
[2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide]. Preemergence or
preplant incorporated herbicide mixtures were applied at common usage rates and
compared for their effects on weed cover, weed species stability, and grain
production. All plots were essentially weed-free the first year. Weed cover in
most treatments increased significantly by the second year with fall panicum
(Panicum dichotomiflorum Michx.) dominating the flora in Years 2 and 3, and
smooth pigweed (Amaranthus hybridus L.) dominating in Years 4 and 5. Smooth
pigweed reached densities of 85% in several treatments. Fall panicum was the
dominant weed in pre-plant incorporated treatments that contained atrazine [6-
chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine] plus a
carbamothioate herbicide. Grain yields were negatively correlated with fall
panicum densities in the second year in all herbicide treatments. Smooth
pigweed densities were negatively correlated with grain yields in the fifth
year in all preemergence treatments. Smooth pigweed densities were lower in
triazine plus alachlor treatments than in double triazine treatments for the
last 2 yr of the study.

Abstract: Vetch (Vicia villosa Roth), clover (Trifolium incarnatum L.), and
fallow (no winter cover crop) were used as mulch crops preceding cotton
planted in a conservation tillage system. In field tests, cotton emergence and
survival were reduced in legume mulches with significant differences at the
second planting in 1985. Assessments of Rhizoctonia soil infestation estimated
using a modified stem trap baiting procedure, indicated higher amounts of
Rhizoctonia in cotton following legume crops than in cotton following fallow.
In greenhouse studies, comparisons of warm (29 +/- 2 degrees C day and 21 +/-2
degrees C night) and cool (29 +/- 2 degrees C day and 10 +/- 2 degrees C night)
temperature regimes imposed on the clover, vetch and fallow treatments,
demonstrated that the cool temperature regime significantly reduced emergence
and survival of cotton seedlings. However, there was no interaction of
cropping treatments (legume cropped or fallowed treatments with temperature
regimes). Cotton seedling disease severity in the greenhouse assay of
field-collected soil samples showed a significant interaction among year, soil
treatment and temperature.

Abstract: Increasing concerns about soil degradation with continuous corn (Zea
mays L.) production and a scarcity of scientific information regarding corn
grown in rotation with the diversity of crops produced in Ontario,
prompted a long term study on the effect of various crop rotations and their
interaction with two tillage systems on corn growth and soil structure. Eight
rotations were established in 1980 which included continuous corn, six
rotations comprised of 2 yr of corn following 2 yr of another crop or crop
sequence, and continuous alfalfa (Medicago sativa L.). Each rotation was
divided into either conventional tillage (fall moldboard plow) or minimum
tillage (fall chisel plow). First-year corn grown in rotation yielded 3.9% more
than continuous corn for conventional tillage and 7.9% more than
continuous corn for minimum tillage. These corn responses to rotation were
smaller than most of those reported in the literature. When barley (Hordeum
vulgare L.) or wheat (Triticum aestivum L.) were the preceding crops,
interseeding red clover (Trifolium pratense L.) increased first year corn
yields only on conventionally tilled plots. Corn plant development was
consistently slower with minimum tillage compared to conventional tillage.
Yields were significantly lower with minimum tillage for continuous corn and
where corn followed wheat interseeded with red clover. Little or no response to
rotation was observed in second-year corn. The seedbed with continuous corn had
a lower proportion of fine aggregates compared to corn grown in rotation. In
most years soil aggregate stability was highest under continuous alfalfa and
including a legume (whether alfalfa or interseeded red clover) in the rotation
improved aggregate stability compared to continuous corn.

Abstract: An experimental bed-forming machine was designed and developed for
the operational conditions of controlled-traffic, tillage, cropping systems on
the Texas Blackland Prairie. The machine was front mounted on a
two-wheel-drive tractor to cut two spaced furrows and form raised wide beds
when initiating such a tillage and cropping system. Subsequent rebedding was
conducted after one or more cropping years, when the soil was covered with crop
residues. The experimental machine was satisfactory in difficult clay soils.
Alternative furrow plows could be used for other soil conditions.

Abstract: Field trials in Ohio have shown that the Bray-1 P soil-test level
for optimum corn (Zea mays L.) production is greater for no-till than for
conventionally (moldboard plow) tilled corn. Studies using Hoytville silty clay
loam (fine, illitic, mesic Mollic Ochraqualf) and Canfield silt loam (fine-
loamy, mixed, mesic Aquic Fragiudalf) taken from long-term no-tillage plots
indicated decreased retention of P against the Bray-1 extractant in surface
soils, compared with samples from deeper within the soil profile. In an effort
to further examine the P-retention characteristics of no-till soil profiles,
experiments were prepared using P-sorption isotherms, before and after a series
of sequential anion resin extractions. Prior to sequential extractions, the
isotherms showed decreased sorption of P at the soil surface (0-2 cm), compared
with deeper soil layers. Resin extraction removed more P from surface layers
than deeper depths, and the quantity of P removed with each extraction declined
much more quickly in the surface layers than in lower depths. After resin
extraction there was a trend for greater retention of P against the Bray-1
extractant in the upper soil layers. Sorption isotherms created after resin
extraction show increased P sorption at all depths and closer agreement between
the shape of the isotherm curves. It appears that accumulated P on the soil
surface saturates P fixation sites, resulting in differential retention of P
with depth.

Abstract: A linear programming model was used to determine which crop
rotations and weed management systems result in the highest net farm income for
each of three farm sizes (120, 240, and 480 hectares) under alternative tillage
systems. Test plot data for the years 1981 through 1988 from the
Purdue University Agronomy Farm, which has highly productive, well-drained
soils, were analyzed. Net incomes for no-till tillage systems on all farms in
the model were consistently and significantly lower than incomes for moldboard
and chisel plow tillage systems due to slightly lower yields and substantially
higher herbicide costs. Generally, net farm incomes were slightly higher with a
moldboard plow versus chisel plow tillage system. Also, as farm size
increased, per hectare net incomes increased. About 80% of the time under
moldboard or chisel plow tillage systems, the model chose as optimal the
lowest of three herbicide application rates. A corn/soybean rotation was
chosen as optimal on 56% of the farm area analyzed, versus 25% for continuous
corn and 13% for a corn/soybean/wheat rotation.

Abstract: Two varieties of winter rapeseed (Brassica napus) (Cobra and
Liborius) were planted at Brownstown, IL to evaluate the effect of planting
date, nitrogen (N) rate, N application timing, and tillage on grain yield and
oil content of the grain, grain moisture, plant lodging, winter survival, and
plant N content. Results indicated that planting rapeseed approximately one to
two weeks prior to winter wheat in this region is preferable to planting
earlier. Grain yield showed a significant linear increase with delayed
planting date from 25 August to 24 September. Grain yield also increased
quadratically with increasing N rate (with an optimum of about 250 kg N/ha) and
increased (0.15 Mg/ha) due to splitting the N fertilizer into two even
applications. An increase in grain yield was accompanied by an increase in
grain moisture with Liborius (late maturing) having significantly greater grain
moisture than Cobra. Winter survival increased linearly with delayed planting
date but, was accompanied by a significant quadratic increase in plant lodging.
Chisel, as compared to disk tillage, increased plant lodging slightly, but
decreased winter survival slightly. Neither delayed planting, N rate, nor
splitting of spring N affected oil content. Liborius produced
significantly more oil than did Cobra.

Abstract: Between June 1988 and October 1989 the effect of soil compaction on
abundance and biomass of active lumbricids was investigated in a longterm field
experiment under spring-wheat and winter-barley. Seven plots were
subjected to loads by agricultural machinery under conditions simulating three
common kinds of agricultural practice and compared to an unloaded control plot
(Table 1). The dominant species of the investigation area, Aporrectodea
caliginosa and A. rosea (99.3% of total individual number) had their highest
activity and biomass in the uncompact control plot. Lowest individual numbers
were found in the extremely loaded wheel-track and the conservation tillage
area. The extensive cultivation of this area began just at the start of the
field experiment, so that a greater earthworm population had not had time to
establish itself In pot experiments the activity of the endogeic species A.
caliginosa was investigated in tripartioned soil columns (40 cm long X 19 cm
wide), each differently compact to pore volumes (pv) of 37.5, 42.5, 47.5 and
56%. A significantly higher activity, measured as the length and the number of
the burrows visible from outside, was found in the lighter substrates. The
volume number extent of earthworm burrows was as much as 2 times higher in the
47.5 and 56% pv columns than in the more compact 42.5 and 37.5% pv columns.

Abstract: Experiments were conducted on a Cedarbluff silt loam and a Cecil
sandy loam to determine dissipation of imazaquin and imazethapyr as influenced
by burning small-grain straw and tillage prior to soybean planting. Corn
bioassay detection limits for imazaquin and imazethapyr in the Cedarbluff silt
loam were 2.5 to 30 and 5 to 40 ppbw, respectively. Bioassay detection limits
for imazaquin and imazethapyr in the Cecil sandy loam were 2.5 to 20 and 10 to
40 ppbw, respectively. Imazaquin and imazethapyr activity was not detectable in
soil by 110 to 152 d after treatment. Imazethapyr dissipation was not
affected by burning or tillage in the Cedarbluff silt loam and dissipated more
slowly in 1989 than imazaquin. Imazaquin dissipation in the Cedarbluff silt
loam in 1988 was slower in burned plots than in nonburned plots but was not
affected by burning in 1989. No differences were observed between imazaquin and
imazethapyr dissipation in the Cecil sandy loam and neither burning or tillage
influenced their rate of dissipation in either year. No-till-planted cotton was
injured at both locations by imazaquin and imazethapyr that had been applied
the previous year.

Abstract: Increased use of conservation tillage by midwestern corn growers in
the 1970s and 1980s has led to a greater incidence of problems with the stalk
borer, Papaipema nebris (Guenee). In particular, serious infestations have
occurred throughout entire fields where no-till is practiced. A 3-yr factorial
experiment (1983-1986) assessed the effect of three tillage practices (fall
moldboard plow and spring disk, fall chisel plow and spring disk, and no-till)
at two levels of weed management (weed growth present or absent in spring) on
the survival of stalk borer eggs and development of larvae from surviving eggs.
Injury to corn was used as a relative measure of stalk borer survival. Egg
masses were infested on or immediately adjacent to grassy weeds after harvest
but before tillage operations took place. Winter wheat was sowed in the fall to
supplement natural weed growth in the plots with no weed control. In plots with
the high level of weed control, plant growth was controlled, as needed, with
paraquat in spring before planting. In all three studies, the tillage X weed
management interaction was not significant and the
moldboard-plow treatment significantly decreased stalk borer damage when
compared with the no-till treatment. The chisel-plow treatment was generally
intermediate between the no-till treatment and the moldboard-plow treatment in
reducing stalk borer damage. The absence of weed growth in spring tended to
decrease infestations of larvae, although the difference in damage between the
two levels of weed management was significant in only one of the study
periods. In that period, the interval between predicted 50% stalk borer egg
hatch and the one-leaf-stage of corn development was greater than that
interval for the other two studies. Even with the burial of eggs by soil with
the moldboard-plow treatment, some larvae successfully eclosed and survived to
damage corn seedlings in two of the three studies, with or without the
presence of weeds. Although the resul

Abstract: The effect of tillage systems on depth of emergence and densities of
giant and green foxtail under different environmental and cropping
conditions were evaluated from 1985 to 1987 at Arlington, Hancock, and
Janesville, WI. Mean emergence depths in no-till were the shallowest, followed
by chisel plow and conventional tillage at each location. At least 40% of the
giant and green foxtail plants emerged from the upper 1 cm of soil in no-till
compared to about 25% in chisel plow and less than 15% in conventional
tillage. As many as 25% of the plants emerged from greater than 4 cm in
conventional tillage compared to about 10% in chisel plow and less than 5% in
no-till. Seedlings emerged from greater depths in a loamy sand than in a silt
loam soil regardless of tillage system. At Arlington, green foxtail was the
dominant species in conventional tillage, while giant foxtail dominated in
chisel plow and no-till. Foxtail densities were greater in chisel plow and no-
till than in conventional tillage at all three locations.

Abstract: We tested two agronomic practices that are likely to increase plant
and structural diversity, no-tillage and strip intercropping, for effects on
corn invertebrate fauna. Some of the most common herbivores and natural
enemies were sampled by direct counts and damage estimation from 1988 through
1990 on monoculture corn and strips of corn alternated with soybean, under no-
tillage and conventional tillage. Among soil pests, cut-worms (mostly the black
cutworm, Agrotis ipsilon (Hufnagel)); armyworm, Pseudaletia unipuncta
(Haworth); and slugs (Gastropoda) were more abundant in no-tillage plots,
although only slugs caused severe damage. The western corn rootworm,
Diabrotica virgifera virgifera LeConte, and the European corn borer, Ostrinia
nubitalis (Hubner), were generally more abundant in conventional tillage
plots. Despite crop rotation, the strip-intercropping system (four rows of each
crop) was less effective in reducing western corn rootworm infestation,
especially in conventional tillage plots. In 1990 only, ladybugs (mostly
Coleomegilla maculata (DeGeer)) were more abundant in conventional tillage
plots, whereas tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois),
were more abundant in no-tillage plots. Japanese beetle, Popillia japonica
Newman; stink bugs, Acrosternum hilare (Say) and Euschistus serous (Say); and
spiders (Aranea) were not significantly affected by treatments.

Abstract: Effects of tillage and herbicide application method on the
persistence and residual activity of clomazone, imazaquin, and imazethapyr were
investigated in a 2-yr field study. Herbicides were applied preemergence and
preplant incorporated to conventional- and reduced-tillage soybeans in 1987 and
1988. Herbicide dissipation was monitored using chromatographic and bioassay
techniques. In 1987, dissipation rates for clomazone, imazaquin, and
imazethapyr were similar, regardless of tillage system or application method.
In 1988, all three herbicides applied preplant incorporated dissipated more
slowly than in preemergence treatments. Corn planted in rotation in 1989
displayed greater levels of injury in the incorporated treatments for all three
herbicides. Although herbicide concentrations were similar 322 d
following application in both tillage treatments in 1989, corn injury was
greater with imazaquin and imazethapyr and less with clomazone in the
reduced-tillage plots than in the conventional-tillage treatments.

Abstract: The effect of different levels of tillage and weed management on
population, distribution, and germination of weed seed was evaluated in three
tillage systems at Arlington and Hancock, WI, in 1989 and 1990. Over 60% of all
weed seed in the top 19 cm of soil were found in the top 1 cm in
no-tillage at both sites. As depth increased, concentration of weed seed
declined logarithmically in no-tillage. In chisel plowing, over 30% of seed
were in the top 1 cm and seed concentration decreased linearly with depth.
Moldboard plowing had uniform distribution of weed seed in the top 19 cm of
soil. Preemergence metolachlor plus atrazine decreased weed seed population by
50% compared with no treatment over all tillage systems. One year of the
herbicide treatment plus handweeding to assure weed-free conditions did not
reduce seed numbers in chisel plowing or moldboard plowing compared to
herbicide alone. Seed numbers with no-tillage and weed-free conditions
decreased by 40% relative to herbicide alone. Common lambsquarters germination
was 40% greater in moldboard plowing and chisel plowing compared with
no-tillage. Germination was highest in seed taken from 9 to 19 cm deep in
moldboard plowing and from 0 to 9 cm deep in chisel plowing.

Abstract: The objective of this field research was to compare relative
effectiveness and profitability of alternative herbicides applied to the same
plots for four consecutive years for controlling and reducing dense Canada
thistle infestations in no-till spring wheat. Chlorsulfuron at 30 g ai ha-1
plus nonionic surfactant or clopyralid plus 2,4-D at 70 plus 280 g ae ha-1,
respectively, applied annually for 4 yr controlled Canada thistle and was more
effective for gradually reducing Canada thistle stands than 2,4-D at 560 g ae
ha-1, MCPA plus bromoxynil at 280 plus 280 g ae ha-1, or tribenuron at 20 g ai
ha-1. Chlorsulfuron and clopyralid plus 2,4-D also controlled Canada thistle
greater than or equal to 90% earlier (by 2 yr) than other treatments.
Stochastic dominance analysis, a form of economic analysis, predicted that
either chlorsulfuron or clopyralid plus 2,4-D would be preferred by farmers to
the untreated check, MCPA plus bromoxynil, or 2,4-D treatments. Chlorsulfuron
also would be preferred to clopyralid plus 2,4-D by risk-neutral farmers,
whereas clopyralid plus 2,4-D would be preferred to chlorsulfuron by highly
risk-averse farmers, those who are most likely to pick only consistently
effective herbicides.

Educational programs
Abstract: Two independent, but closely related, grant funded educational
programs were developed and implemented to reduce soil erosion in selected
areas of eastern Nebraska. Traditional extension programming methods as well as
other more non-traditional approaches were used extensively to enhance soil
conservation practice adoption. In one program, encompassing 220 000 ha
(540,000 acre) of cropland, annual soil erosion was reduced by 2.3 million t
(2.5 million ton) and annual fuel savings of 1.5 million L (390,000 gal) were
achieved through a reduction in the number of tillage operations. In the
second project, more than 93 000 m (305,000 ft) of terraces were constructed,
which resulted in an annual soil erosion reduction of 151 000 t (166,000 ton).
These projects demonstrated that targeted conservation programs can be very
effective.

Abstract: Percentage hatch, chewing predation, Chrysopa sp. predation, other
sucking predation, and parasitism by Trichogramma sp. of egg masses of
first-generation Ostrinia nubilalis (Hubner) were estimated in spring chisel
plow, ridge tillage, and no-tillage maize, Zea mays L., in southeastern
Minnesota during 1986 and 1987. Tillage plots were split with and without
terbufos application and with and without Bacillus thuringiensis-permethrin
application in all combinations. Egg masses from laboratory reared O.
nubilalis were exposed to natural enemies in the field eight times during the
oviposition period of first-generation O. nubilalis, and population densities
of Coleomegilla maculata DeGeer were estimated. Parasitism was 0.6% and
predation was low during 1986. During 1987, chewing predation was highest in
the chisel-plow system and lowest in the no-tillage system; Chrysopa sp.
predation was lowest in the chisel-plow system and highest in the no-tillage
system. C. maculata population densities were highest in the chisel-plow
system and lowest in the no-tillage system, and chewing predation was
positively related to C. maculata density. Predation by other unknown chewing
predators was also higher in the chisel-plow system and lowest in the
no-tillage system. The inverse relation between chewing and Chrysopa sp.
predation was probably related to species-specific responses to the tillage
environments.

Abstract: Improved fertilizer N management with respect to placement and
timing is especially important in high-residue systems designed to improve N-
use efficiency and to speed adoption of erosion controlling tillage
practices. By means of point-injection technology, fertilizer solutions now can
be applied and soil-incorporated with minimal disturbance of surface
residue or existing plants. This study was conducted in large non-weighing
lysimeters (with reconstituted soil horizons) to determine the recovery of 15N-
labeled urea-ammonium nitrate (UAN) solution by continuous no-till corn (Zea
mays L.) during the initial year of application and two subsequent years for
four N management systems. The UAN solution was point-injected in split
applications at rates of 125 or 200 kg N ha-1, or knifed-in or surface-banded
right after plant emergence at 200 kg N ba-1. For the initial year of 15N
application, the percent recovery of labeled N (NR) in grain was 48, 39, 33,
and 30% for point-injected (low rate/split), point-injected (high rate/split),
knifed-in, and surface-banded, respectively. The percentage of total grain N
derived from labeled N (Nf) ranged from 57 to 67% and was in the order of
point-injected (high rate/split) > knifed-in > point-injected (low rate/split)
> surface-banded. Residual labeled N recovery in grain ranged from 2.3 to 4.6%
for the second season and from 0.9 to 1.0% for the third season with no
significant differences among application treatments for either season. After
rive seasons the NR values for labeled N determined in the soil N pool still
ranged from 20 to 26%. UAN solution applied in split applications with the
point injector was used more efficiently by corn than when knifed-in or
surface-banded in a single application, indicating the point-injection/split
application system is an option for improved N management in no-till corn.

Abstract: Little information is available concerning tillage effects on
seasonal N accumulation and their effect on wheat yield. Field studies were
conducted to determine the effects of fertilizer N placement and tillage
practices on the reduction and assimilation of N in winter wheat (Triticum
aestivum L.) during 1984 through 1987 on Renfrow silt loam (fine, mixed,
thermic, Uderic, Paleustolls) near El Reno, OK. Fertilizer N (50 kg ha-1) and P
(60 kg ha-1) including 4 kg N ha(-1) and 11 kg P ha(-1), with the seed was
applied in the fall. In the spring, an additional 50 to 100 kg N ha(-1) as
ammonium nitrate was either broadcast or placed in narrow bands on the soil
surface. Nitrate reductase (NR) activity, NO3-N, and crude protein (CP)
content of wheat plants were determined periodically during spring growth until
anthesis, and final grain and straw yield and their CP contents were
determined. The NR activity in early spring was slightly greater during early
spring in plants grown under no-till when compared to conventional till in 1985
and 1986, whereas the reverse was observed in 1987. lncreased NR activity was
paralleled by an increase in vegetative CP. Placement of N in a narrow band on
the soil surface in the spring improved NR activity levels, but the effect of N
placement had little effect on CP concentration. Grain yield
followed NR activity levels and was 36% higher in no-till in 1985, similar in
1986, but 51% lower in 1987 than conventionally tilled plots. Placement of N in
narrow bands increased N-use efficiency by increasing N reduction and
assimilation; but had little effect on the yield of grain and straw in both
tillage methods.

Abstract: Winter wheat (Triticum aestivum L.) is grown under both
conventional-till and conservation-till systems in the Northern Great Plains. A
benefit of sowing winter wheat into standing stubble is the protection the crop
receives from trapped snow and the resultant reduction in winter kill. A 5-yr
study was conducted at four locations in North Dakota to measure
cultivar-by-tillage interactions for quality parameters of wheat and to
determine whether testing under both conventional-till and no-till systems was
advantageous. Fourteen hard red winter wheat cultivars were planted during
1984-1985 through 1988-1989 in a Max loam (fine-loamy, mixed, Typic
Haploborolls) at both Williston and Minot, in a Svea loam (fine-loamy, mixed,
Pachic Udic Haploborolls) at Langdon, and in a Bearden silty clay (fine-silty,
frigid, Aeric Caldaquolls) or Gardena silty loam (coarse-silty, mixed, Pachic
Udic Haploborolts) at Fargo. Significant cultivar-by-tillage interactions (P <
0.05 or P < 0.01) were obtained for volume weight, protein content, and flour
when the analysis was restricted to environments in which wheat winter killed.
A change in rank order of cultivars was detected only for volume weight. For
the other quality parameters measured, evaluation of winter wheats grown in
conventional-till and no-till plots resulted in similar relative performance of
cultivars.

Abstract: Population estimates of the cricket Allonemobius allardi (Alexander
& Thomas) in orchardgrass, Dactylis glomerata L.; alfalfa, Medicago sativa L.;
and weedy fields revealed significantly lower cricket densities for alfalfa
compared with orchardgrass and weed fields. However, densities were not
significantly different between orchardgrass and weed fields despite a
considerable dissimilarity in vegetative composition. Laboratory feeding
studies suggest that crickets preferred to forage on the substrate and had
difficulty recognizing preferred food plants that were elevated above the
substrate. Crickets preferred alfalfa to bluegrass, thatch, or oats, but
preferred bluegrass to thatch. No significant difference in feeding was
observed between whole alfalfa leaves and alfalfa leaf disks when both were
placed horizontally on the testing arena substrate. The contents of crops from
field-collected crickets showed Alternaria, rust spores, and fungi occur
relatively frequently but do not account for a substantial percentage of
cricket crop contents. Legumes and dandelion also occur with a moderately high
frequency and are a major component of crop contents. Cage tests in glasshouse
and field showed one to two cricket adults per 0.09 m2 reduced alfalfa
seedling numbers by 1-20% in the 2 wk from seedling emergence to formation of
the first trifoliate in conservation-tillage systems when alfalfa was planted
in oat stubble.
