@TheHuxleyLC


Welcome to the Iowa 2016 Agronomic Research Summary Book. As a leader in providing germplasm, traits, chemistries and data analytics to growers in Iowa we feel we also must provide agronomic solutions. Monsanto’s Technology Development and Agronomy group is always looking for ways to improve yield, efficiency and most of all profitability for our farmer customers. This book summarizes some of the key research that has taken place over the last year at various locations throughout Iowa. The locations are selected to represent different geographies, relative maturities, soil types and environmental conditions across the state of Iowa. We feel this is information that can help you become better informed and can help you make better decisions in your farming operation.

Our central location for the state is the Huxley Learning Center. This is one of several sites across the state where agronomic research as well as corn and soybean germplasm breeding trials are planted, evaluated, maintained and eventually harvested to continue to improve on our products and knowledge. The Huxley Learning Center site is always welcome to host visitors and last year hosted over 7000 visitors for training and tours. The Learning Center has state-of-the-art facilities for both indoor and outdoor tours.

Sincerely,

Brent Schwenneker

Huxley Learning Center Manager

HIGH YIELD MANAGEMENT SYSTEMS IN SOYBEAN

TRIAL OVERVIEW

• Achieving high yields in soybean production involves effective management of resources including, but not limited to,seed product selection, seeding rate, soil fertility, and eliminating or reducing the impact of plant stressors.

• In some situations soybean has not been managed as intensely as corn, possibly resulting in not reaching maximum yieldpotential.

• Nearly all corn products on the market have some form of seed treatment; however, estimates indicate only 60 to 70% ofsoybean products planted in 2014 had a seed treatment applied.

• In some locations and years, seed treatments are necessary for protection against seedling diseases and insects.• What are important components of high yield soybean management systems?• Is there an additive effect with each individual management practice contributing to yield potential?

RESEARCH OBJECTIVE

• The objective of the study is to evaluate the effect of various inputs contribution to increasing soybean yield potential andmaximizing net economic return.

UNDERSTANDING THE RESULTS

Table 1. Treatment Summary Figure 1. Effects of management practices on yield and profitability of soybean.

• Under these conditions, adding treatments of seed applied TagTeam® LCO XC, foliar applied fungicide/insecticide, andside-dressed nitrogen as cumulative treatments resulted in progressive yield increas

• As yields increased with the addition of input treatments, gross income minus treatment costs increased as well, except forthe starter fertilizer treatment.

• Under these research conditions, starter fertilizer treatment (AS) had minimal yield effect and provided the same economicreturn as the base treatment (A).

WHAT DOES THIS MEAN FOR YOUR FARM?

• Generally, starter fertilizer is not recommended when planting soybean and was confirmed under these researchconditions.

• TagTeam® LCO XC may increase nitrogen fixation, improve nodule formation, and improve phosphorus availability. Thisseed treatment may also increase yield potential, especially on rotated fields.

• The foliar-applied fungicide and insecticide application was profitable under these research conditions. If diseases andinsects are usually present in your fields, scout fields on a regular basis.

• Applying different foliar treatments in one application can optimize application costs and maximize economic gains.• Nitrogen fertilizer application is generally not needed in soybean. However, in high-yielding environments there may be a

positive yield response.SOURCES1 Beegle, D.B., Roth, G.W, and Lingenfelter, D.D. 2007. Starter fertilizer. Agronomy Facts 51.

ROW SPACING, POPULATION, AND FUNGICIDE EFFECTS ONSOYBEAN YIELD

TRIAL OVERVIEW

• Agronomic practices, such as row spacing and planting population, have varying effects on yield potential. Narrow rowspacing and increased planting rates allow for more rapid canopy closure, which may reduce in-season weedcompetition.1

• Depending on growing conditions and management practices, higher planting rates can result in greater yield potential.2

When growing conditions are conducive to disease development, the application of a fungicide may help protect yieldpotential.

RESEARCH OBJECTIVE

• This study was conducted to help provide information to growers on the effects of row spacing, planting population, andfungicide application in soybean.

SITE NOTES:• Management: Application of standard preemergence and postemergence herbicides; broad-spectrum insecticide. • Products: Six soybean products ranging from 3.0 to 3.6 with Roundup Ready 2 Xtend® soybeans and Genuity® Roundup

Ready 2 Yield® soybean trait packages were evaluated. • Trial Design: Single non-replicated strip trial.• Treatments:

-- Crop protection (fungicide (fluxapyroxad plus pyraclostrobin at 4 oz/acre) application at R3 and untreated check) -- Seeding rate (120,000 (120K) and 150,000 (150K) seeds/acre) -- Row spacing (20 and 30 inches)


Figure 1. Average yield response of soybean to row spacing, plantingpopulation and fungicide treatment. Yield was adjusted to grain moisture of

13%.

• The fungicide application improved average yield across planting populations and row spacing.

• Average yields were higher for 150K seeds/acre than in 120K seeds/acre across row spacing and fungicide treatments.• Across fungicide treatments and planting population, average yields were higher in 20-inch rows than in 30-inch rows.


• Is there a benefit to fungicide application? -- For this study year and location, an average yield benefit of about 8 bu/acre was observed with the application of a fungicide at the R3 growth stage. -- Growing conditions favored the development of diseases common to the region. Moderate levels of frogeye leaf spot and Septoria brown spot were observed in untreated plots. Also, monitor for white mold as it can be problematic in high yield environments, narrow row spacing, and high planting populations. -- Growers are reminded to pay attention to the economics of fungicide applications as they may not always be justified depending on the weather conditions, crop susceptibility, and several other factors. • How does row spacing affect yield potential?

-- In this single-year study, 20-inch row spacing out-yielded 30-inch row spacing by approximately 3 bu/acre. -- Equipment availability may affect the decision to plant narrower rows on individual farms.• Will higher planting populations affect yield potential?

-- In this single-year study, the planting population of 150K seeds/acre out-performed 120K seeds/acre by approximately 2.5 bu/acre across row spacings and the fungicide application. -- It should be noted that final harvest population in soybean fields may be affected by many factors and does not always reflect the intended planting population. • Results from this trial indicated that yield potential may be improved when soybean are planted in 20-inch rows at a

planting population of 150K seeds/acre. This research location has a history of soybean diseases; therefore, a fungicideapplication increased protection of yield potential.

NITROGEN APPLICATION UTILIZING THE CLIMATEFIELDVIEW™ PRO NITROGEN MONITORING TOOL

TRIAL OVERVIEW

• Each year, farmers need to make important decisions about nitrogen (N) fertilization: the right source, right rate, right time,and right placement. 5

• Farmers typically apply a standard fertilizer rate before planting and adjust for corn-on-corn versus corn/soybean rotation,or adjust for yield target.

• The nitrogen monitoring tool by Climate FieldView™ Pro adjusts N forecasts based on factors including soil type, tillage,percent organic matter, cation exchange capacity, and yield target.

RESEARCH OBJECTIVE

• This study was developed to provide information for farmers on how the Climate FieldView™ Pro nitrogen monitoring toolmay assist farmers in managing their nitrogen application and usage in the most profitable way when compared to localstandards.

• Climate FieldView™ Pro nitrogen monitoring tool can help add value throughout the growing season.• In a challenging year to research N, Climate FieldView™ Pro nitrogen management tool gave insights throughout the

season at these five locations to improve potential profit (Table 3).• As the growing season progressed, the Climate FieldView™ Pro nitrogen monitoring tool continued adjusting to current

conditions and gave insights to apply, on average, 14 pounds less N on Treatment #6 while maintaining yield levels topush profitability greater than $28/acre compared to Treatment #5.

• The nitrogen monitoring tool adjusted throughout the growing season as conditions changed (Figure 3). • The starting target was an extra 40 lbs on March 24th. By the middle of August, conditions were favorable for increased

mineralization which led to an increase of 25 lbs of N forecasted to remain at maturity.• How can a nitrogen stabilizer be used to affect the results? At the Storm Lake, IA location, N-Serve® nitrogen stabilizer was

applied to the field. The nitrogen monitoring tool forecasted reduced rates of N in Treatments #2, #4, and #6 which led togreater profitability in all three comparisons at that location (Figure 2).

• Conditions by year and location may have variable effects on available nitrogen.

HIGH YIELD MANAGEMENT SYSTEMS IN CORN

TRIAL OVERVIEW

• Many corn production factors are not easily altered so growers must focus on factors that can be changed. Annualproduction decisions include: soil fertility, seed treatment options, and pest management.

• With the current market trend, growers are contemplating cutting corn production cost by eliminating or reducing someinputs.

RESEARCH OBJECTIVE

• The objective of this trial is to help determine the value soil fertility management and crop protection practices bring tofarm operations in the face of lower commodity prices.

SITE NOTES:• A 112 relative maturity SmartStax® RIB Complete® corn product was selected for the trial.• Eight different treatments evaluated the use of seed treatments, fertilizer, and pesticide applications. Corn products were

planted in 30-inch row spacing with 6 rows/treatment.• Foliar fungicide and insecticide were applied at VT/R1 growth stage at manufacturers recommended rates. • 32% UAN was used for all sidedress applications at V5 (N1) and VT/R1 (N2) growth stages.


Table 1. Treatments to evaluate high yield management systems in corn.1QuickRoots® (Q) cost $6.00/acre; 2Starter Fertilizer (S) cost $12.00/acre;

3Sidedress Nitrogen (N1) cost $17.10/acre; 4360 Y-DROP® Nitrogen (N2) cost $17.10/acre; N1+N2 cost $ 17.10/acre;

5Fungicide and Insecticide application cost $32.00/acre.

• Nitrogen 360 Y-DROP® was applied at VT to R1 growth stage. • Fertility - All treatments received 115 lbs N/acre of anhydrous ammonia in the fall of the previous year.

-- Treatments A, AQ, AQS, and AQSFI received an additional 60 lbs N/acre of 32% UAN following planting. -- Treatments AQN1 and AQN2 received 105 lbs N/acre of 32% UAN in their respective applications. -- Treatments AQSN1N2 and AQSN1N2FI each received 60 lbs N/acre as sidedress and 45 lbs N/acre as 360 Y-DROP applications. The Climate FieldView™ Nitrogen Monitoring Tool was used to provide N application insight. • QuickRoots® and starter fertilizer did not improve yield potential.• Yield was nearly the same for all fertility treatments.• Timing of N application had minimal effect on yield potential.• Yield was nearly the same for the two fungicide and insecticide (FI) treatments.


14

• Foliar FI improved yield potential: -- FI applications provided ≈12 bu/acre yield increase with a revenue of $37/acre. (input cost of FI application $32/acre (Table 1); economic return of $5/acre (revenue $37–input cost $32) -- Treatments containing FI applications (AQSFI and AQSN1N2FI) were less economical due to costs of starter fertilizer and sidedress N components (S, N1, and N2) that did not contribute to improved yield potential.• Acceleron® Seed Applied Solutions ELITE (A) and Acceleron® Seed Applied Solutions ELITE + QuickRoots® (AQ) were the

most profitable treatments at $753/acre each.


• Yield response to agronomic inputs is highly dependent on the corn product, soil, and environmental conditions during the growing season causing different responses from year to year.• Early- and mid-season (especially during pollination) stresses have significant negative impacts on yields.

-- The FI application was necessary to help protect yields due to a wet spring which predisposed plants to stresses followed by the hot, dry midsummer. -- The 112-day corn product responded positively to FI applications with a 12-14 bu/acre yield advantage over the other treatments.• Corn product did not respond to starter fertilizer application.

-- Starter fertilizers are most beneficial when planting into cold, wet soils, or when soil fertility is marginal, opposite of the conditions for this trial. • QuickRoots® enhances nutrient mineralization and nutrient availability to plants.

-- QuickRoots may be the reason why the different N rates and timings had minimal effects on yield potential. -- In marginal fertility fields, QuickRoots may be a great input to optimizing yield potential.

DROUGHTGARD® HYBRIDS CORN PRODUCT PERFORMANCE BYPOPULATION DENSITY

TRIAL OVERVIEW

• In geographies where corn production is limited by water availability, products that can produce high yields while usingwater efficiently are in high demand. DroughtGard® Hybrids corn products are the result of a combination of traditionalbreeding and trait technology and are well suited for areas prone to high levels of water stress and drought, such as areasof the great plains including Kansas, Texas, and Nebraska. These products may also be beneficial in areas with traditionallyhigh yielding environments where water is typically not the most limiting factor, particularly when unexpected droughtconditions arise. The effect of population density on yield in expanded geographies will influence management decisionson a field-by-field basis.

RESEARCH OBJECTIVE

• Determine how DroughtGard® Hybrids corn products perform in expanded geographies of Iowa.• Evaluate the effects of planting population on the yield of DroughtGard® Hybrids corn products.

• In general, greater performance was seen in planting populations exceeding 32K seeds/acre. The highest plantingpopulation (40K) out-performed the lowest planting population (32K) by 12 bu/acre and the mid population (36K) by 4bu/acre.

• Variation by individual corn products was observed but yield remained above 220 bu/acre in all cases.


• Are DroughtGard® Hybrids corn products a good fit for your geography? - Even at planting populations considered to be low for the study area, the products evaluated yielded 229 bu/acre on

average and up to 255 bu/acre at the highest planting population of 40K seeds/acre. - Selecting DroughtGard® Hybrids corn products may protect yield in years with unpredictable rainfall, and still deliver

consistent yield in years where rainfall is not a factor (such as the study year).• What planting populations are appropriate when planting DroughtGard® Hybrids corn products?

- Individual products respond differently to variable populations and it is important to consider unique conditions whenselecting products and determining what populations are right for your operation.

EFFECT OF RELATIVE MATURITY ON YIELD POTENTIAL OFLATE-PLANTED CORN PRODUCTS

TRIAL OVERVIEW

• In situations where planting may be delayed due to environmental conditions or where re-planting decisions must bemade, making the proper relative maturity (RM) selection is critical.

• Individual growing seasons can vary depending on the number of growing degree days (GDD) accumulated, rainfallaccumulation, nutrient availability, and other factors.

• About 22 GDD are required for a one day increase in RM.1 • Earlier RM corn products can dry down earlier than late RM corn products, which is an important consideration as the

earlier harvest can occur, the more likely chance of avoiding poor weather conditions. Inclement weather late in the seasoncan lead to increased drying costs, increased wear on equipment, increased disease, and reduced grain quality.2

RESEARCH OBJECTIVE

• A demonstration was established to help provide information to growers about how the RM of corn products effects theyield potential of late-planted corn.

SITE NOTES:• Seven corn products spanning from 101 to 113 RM were selected and planted late on June 5, 2016.• This demonstration trial was planted as a single, unreplicated trial with 30-inch row spacing. All other agronomic practices

were standard for local conditions.• Cost and net profit were based on revenue ($3.50/bu) minus cost of drying ($0.04/point of moisture over 15%).• Average yields were normalized to 15% moisture.


Figure 1. Corn product average yield and revenue ($3.50/bu) minus cost ofdrying ($0.04/point of moisture over 15%).

• Later RM products ranging from 108 to 113 day RM averaged 27.25 bu higher and had an average of $39.83/ac higherincome including drying costs, than the earlier RM for this location and year.

• Overall GDD accumulation at Atlantic in 2016 was 334 units higher than the 15 year average, which likely provided fullerseason products with an advantage.3

• A combination of high moisture in May followed by hot and dry conditions in June and a hot July and August with amplerainfall contributed to high GDD accumulation and favorable conditions for full season corn products. Later RM productsbenefitted from continual favorable conditions.

• Corn product RM selection should be considered carefully and selected based on region, climate and potential yield.Planting a variety of corn products with appropriate RMs on a per operation basis can help spread risk and harvest interval.1

• When selecting corn products for re-plant or late planting, dry down should be an important consideration. In thisdemonstration, harvest occurred somewhat early with 101 to 104 RM corn products harvested at 20 to 22 percentmoisture content, and 108 to 113 RM corn products harvested at 26 to 31 percent moisture content. Typically, harvest of afull season corn product would not occur at such a high moisture content and drying costs would not impact profit asgreatly.

• The higher than average GDD accumulation resulted in more favorable conditions for late RM corn products, whereas inother years there would be a risk of corn not reaching blacklayer prior to the first frost.
