2011 Annual Report

Northwest Missouri Demonstration Site

http://extension.missouri.edu/atchison/Graves/Main%20page.htm

Page 2

The Graves - Chapple Research Center is a University of Missouri research and demonstration

site located in southwest Atchison County. Graves - Chapple East is located on the east side of

I-29 at the foot of the bluffs. Graves - Chapple Heitman Farm is on the west side of I-29

adjacent to State Highway111.

The site was established in 1988 as a collaborative effort between Atchison County Extension,

Holt County Extension, the University of Missouri’s Agricultural Experiment Station, local

agribusinesses and local producers. Primary funding is provided by University of Missouri

Extension and the Agricultural Experiment Station.

Projects at this site are devoted to various agronomic practices, with a major emphasis on the

production of corn and soybeans. Work with forages, other row crops and alternative crops is

also conducted. This site is somewhat unique in the state due to the soil types and the

predominance of no-till planting techniques. Soil conservation and water quality issues are also

addressed. The farm strives to perfect practices that will maintain or increase the profitability for

area crop producers.

As everyone involved with agriculture knows, raising crops can be a challenge and 2011 was

no different. Parts of Northwest Missouri saw record floods while other parts received devastating

hail and wind storms. At the center, we were not spared from Mother Nature as our west side plots

were under flood water for over 3 months. While the flood waters provided excellent weed control, it

also presented us with a variety of other challenges and opportunities.

In 1988, one of the major changes occurring was the promotion of the no-till farming system.

No-till was seen as a way to reduce input costs and reduce erosion on our agricultural ground.

Agriculture was being singled out as the major source of pollution in our nations lakes and rivers.

The concept of not tilling the soil was so foreign to most farmers that the concept was thought to be

impractical in Northwest Missouri. “It will not work up here” was a common refrain. Under that

premise, the Graves-Chapple Farm was founded and has proven over the years that no-till is a viable,

profitable and environmentally friendly farming process for Northwest Missouri.

Why do we give you this background? Because the Graves-Chapple Research Center is here

to provide research based information to area producers under local conditions. While the flood was

devastating, we have chosen to look at it as an opportunity to conduct research on restoring flooded

ground to production. We are using the 2011 flood of our plots to develop information on the

impacts to the soil and how best to resume productive agriculture in these situations.

Another change in 2011 was in the name of the farm. The College of Agriculture, Food and

Natural Resources conducts research at outlying locations throughout the state. For the sake of

consistency across the state, all research locations were renamed Research Centers to more closely

represent the activities taking place at these locations. The name may have changed, but the quality

of research and demonstrations you have come to expect has not diminished.

Visitors are always welcome whether you are attending a field day, special tour, meeting, or

just passing through the area. We are pleased that you have picked up this copy of the annual report.

The information in this report is a brief overview for some of the current research and demonstrations

at the farm and we hope that you find the information beneficial to your operation.

If you are not on our mailing list or email list for flyers or meetings and would like to be,

please let us know. We encourage you to ask questions. You are the reason this center exists and

sometimes your questions or suggestions become an entire experiment or demonstration that benefits

many people.

We would also like to thank the members of our Advisory Board for their support and

guidance. Their time and efforts are greatly appreciated.

Objective

Methods & Materials

The objective of this demonstration is

to evaluate the effect of different tillage

systems on corn yields and profitability of the

enterprise. This is the 20th year for this

demonstration.

The four most common tillage systems

practiced in this region were used for this

demonstration. The tillage systems used

were:

Fall & Spring Disk

Spring Disk

No-till

Fall Chisel & Spring Disk

Each plot consisted of eight rows

spaced 30 inches apart and 250 feet long.

Yield results were taken from the center six

rows of each plot. The plots were planted on

May 4, 2011 with a population of 32,401

seeds/acre into a field that raised soybeans in

2010. Harvest was conducted on October 6,

2011.

Tillage Systems in Corn

Results and Discussion

In 2011, the Spring Disk plot had the

highest yield with 245.3 bu/acre. The lowest

yielding system was the Fall chisel and Spring

disk plot which yielded 197.9 bu/ac. The

average for the four systems was 220.5 bu/ac

with a standard deviation of 19.8 bu/ac. Yield

results for all four tillage systems are shown in

Table 1 and Figure 1.

Perhaps the best comparison can be

made by looking at the cumulative results of

the study as shown in Figure 2. This long

term collection of data allows the weather

variable to be minimized since we have had

greatly varying weather patterns during this

time period. During this 21 year period, the

Spring Disk system averaged 173.7 bu/acre.

The Fall and Spring disk treatment had the

lowest average of 168.1 bu/acre. With a

standard deviation of only 2.6 bu/acre over

this period, there is no significant difference

between the yields.

The most important aspect of the

tillage trials is the net bottom line. The

application of fertilizer, herbicides, seed,

planting and harvesting were identical for

each of the tillage systems used. Thus, the

economic differences shown are a result of the

tillage procedures conducted on each plot and

the associated costs.

It is very difficult to estimate tillage

costs as each grower’s operating costs will be

different. Age and size of the equipment, field

shape and size as well as soil type will all

effect the tillage costs. A large variable most

seasons is fuel cost. To come up with a

standard comparison value, we used the rates

from the MU Custom Rates guidesheet for the

various tillage operations performed. These

values are based on data collected from

producers across Missouri. The most recent

guide was updated in 2009. There is no

assurance that these rates would cover a

particular producers costs. However, this is

the best estimate we can find for a comparison

One factor not considered in the

economic analysis is labor. It is almost

impossible to place a value on a producer’s

labor per hour. Therefore, no labor costs are

included in the analysis.

Table 2 provides a summary of the

gross income per acre minus the costs for the

tillage work that was conducted. If we use a

value of $6.00 per bushel, over this 21 year

period the no-till plots grossed $4.81 less than

the Spring disk plots and $40.47 and $43.56

per acre more than the other tillage systems.

Another important factor that is

sometimes not considered is the benefit to the

environment of different tillage practices. No-

till programs greatly reduce the amount of soil

erosion caused by wind and water runoff. Soil

particles are the number-one contaminant

found in the rivers and streams of Northwest

Missouri. These particles not only cloud the

water but they also may have other pollutants

(herbicides, insecticides, fertilizer) adhered to

them which may contaminate the water.

Page 8 Tillage Systems in Soybeans

Disk treatment had the lowest average yield

for any of the treatments with an average of

55.5 bu/ac per year. These yields are shown

in Figure 2.

With eleven years of data, you can see

a trend developing in the yields for each

tillage method. This longer term collection of

data allows the weather variable to be

minimized since we had varying weather

patterns during this time period. The ten year

average for all the plots is 56.5 bu/acre with

only a 0.7 bu/acre standard deviation. This is

not a significant variation between the various

tillage systems.

Objective

Methods & Materials

The objective of this demonstration is

to evaluate the effect of different tillage

systems on soybean yields and profitability.

This is the tenth year for this demonstration.

The four most common tillage systems

practiced in this region were used for this

demonstration. The tillage systems used

were:

Fall Chisel & Spring Disk

No-till

Spring Disk

Fall & Spring Disk

Each plot consisted of eight rows

spaced 30 inches apart and 250 feet long.

Yield results were taken from the center six

rows of each plot. The plots were planted on

May 18, 2011 with a population of 175,402

seeds/acre into a field that was planted in corn

in 2010. Harvest was conducted on October

26, 2011.

In 2011, the highest yielding system

was the No-till plot with a yield of 68.1 bu/ac.

The lowest yielding system was the Fall and

Spring Disk plot which yielded 57.1 bu/ac.

The average yield for the four systems was

59.8 bu/ac with a standard deviation of 5.5 bu/

ac. Yield results for all four tillage systems

are shown in Table 1 and Figure 1.

If you compare the data obtained over

the eleven years of the study, the No-till

treatment has had the highest average yield for

any of the tillage methods with an average of

57.3 bu/acre per year. The Fall Chisel/Spring

The economic analysis follows the

trend we have seen in the corn tillage

demonstrations. The application of the

fertilizer, herbicides, seed, planting and

harvesting were identical for each of the

tillage methods used. With only a 0.6 bu/acre

variation between the treatments, the

economic difference is a result of the tillage

procedures conducted on each plot and the

associated costs. It is very difficult to

estimate tillage costs as producer's operating

costs will be different. Age and size of the

equipment, field shape and size, and soil type

will all effect the tillage costs. As with the

corn tillage demonstration, we used the 2009

MU Custom Rates guidesheet to estimate the

tillage costs for each system used.

One factor not considered in the

economic analysis is labor. It is almost

impossible to place a value on a producer’s

labor per hour. Therefore, no labor costs are

included in the analysis.

Table 2 provides a summary of the

gross income per acre minus the costs for the

tillage work that was conducted. The No-till

plots grossed between $18.10 and $49.59 per

acre more than the other tillage systems

assuming a price of $12.00 per bushel for

soybeans.

Another important factor that is

sometimes not considered is the benefit to the

environment of different tillage practices. No-

till programs greatly reduce the amount of soil

erosion caused by wind and water runoff. Soil

particles are the number-one contaminant

found in the rivers and streams of Northwest

Missouri. These particles not only cloud the

water but they also may have other pollutants

(herbicides, insecticides, fertilizer) adhered to

them which may contaminate the water.

Page 10 Effect of Quadris Fungicide on Yield of

Different Corn Hybrids

Introduction

Methods & Materials

The effect of fungicides on corn yields

has been hybrid specific. University research

indicates that if hybrids are resistant to a

particular disease, there will be little or no

benefit to treating the hybrid with a fungicide.

Check with your seed dealer regarding the

disease package of your hybrid.

Results and Discussion

An off-set boom was fabricated and

attached to the loader bucket of our spray

tractor to apply fungicides to corn after tassel.

Six rows of corn and soybeans were planted

alternating allowing one to drive in the

soybeans and reach over the corn to apply the

spray. The carrier was water applied at 23

GPA. Quadris was applied July 11th at a rate

of 1 pint per acre.

The yield data statistical analysis did

not indicate any significant differences

between treated and untreated. However, the

Pioneer 1395HR shows a trend of the

fungicide application increasing yield.

Each set of bars indicates the yield of

untreated followed by treated. The first two

sets of bars are corn following soybean

residue. The remaining six bars are corn

following corn residue. Again, there were no

significant differences among yields.

/A High water table

Compacted layer 18-inches

Flanary 2011

The high yielding site had water within

one foot of the surface of the plot area by a

drainage ditch. This caused the water table to

be extremely high at this site causing lower

corn yields. Furthermore, the high water table

created a lot of plot to plot variability.

As far as the compacted plot area,

yield was maximized yield at 36,500 plants

per acre. Higher populations caused yields to

decline in these plots.

Results and Discussion Two sites were chosen for testing in

different yield environments. One area is a

compacted site located at the south triangle of

the Graves Chapple Research Center and the

other plot area is located further south. The

compacted layer starts at 18 inches then is

approximately two feet of compacted soil

which was caused by heavy equipment used

during the building of Interstate 29. The other

area is a very productive area that has yield

potentials of over 200 bushels per acre of

corn.

Page 12 The Effect of Different Nitrogen Application

Timings on Corn Yield

Introduction

Methods & Materials

The objective is to measure impact of

split, pre and side-dress application timings of

nitrogen on corn yield. Nitrogen application

timing, given the wet springs, has created

attention with many growers adding

supplemental nitrogen to nitrogen deficient

corn and obtaining excellent responses.

Growers question whether they should split

nitrogen, or if they split nitrogen, what rates of

splits should be used.

The pre-plant nitrogen yielded

significantly better than the side-dress

application. This is the same result as in

2010. The 60 pound pre-plant followed by

120 pounds was not significantly different

from the pre-plant treatment. These results

are shown in Figure 1.

The standard deviation indicated

variability with this treatment however. We

continue to find in loess derived soils with

good drainage, that pre-plant nitrogen

applications at the time of planting perform

better than later side-dress treatments.

In another experiment looking at pre-

plant compared to side-dress nitrogen

application, the same results were found as

shown in Figure 2.

Results and Discussion

Urea treated with Agrotain was used as

the source of nitrogen. Pre-plant nitrogen

was applied May 16th and side-dress

application made June 13th. The corn planting

date was May 16th.

Objective Methods & Materials

Measure the effect of different

nitrogen fertilizer products on corn yield.

A urease inhibitor is used to prevent

volatilization. Thiophosphoric triamide,

commonly referred to as NBPT, has the trade

name Agrotain. This product inhibits the

urease enzyme that converts urea to ammonia.

The addition of this product reduces the

potential volatilization of surface applied urea

containing products.

Nitrification inhibitors retard the

conversion of ammonium to nitrate. The

nitrate form of nitrogen is susceptible to losses

by denitrification or leaching. The benefit

from using an inhibitor varies. Soil

conditions, time of year, type of soil,

geographic location, rate of nitrogen

application, and weather conditions that occur

after the nitrogen is applied and before it is

absorbed by the crop affect the value of

nitrification inhibitors.

Super U contains the urease inhibitor

Agrotain and a nitrification inhibitor DCD

(dicyandiamide).

ESN stands for Environmentally Smart

Nitrogen and is manufactured by Agrium.

Polymer coated urea has a special polymer

coating. Water moves through coating to

dissolve urea. The nitrogen diffuses through

the porous polymer membrane.

Nitrogen products were applied at the

rate of 180 pounds of nitrogen per acre. ESN

was applied with ammonium nitrate per the

recommendation by manufacturer. This is to

insure that enough nitrate nitrogen would be

available soon enough for early season crop

growth. The mix was 75% ESN plus 25%

ammonium nitrate.

The products Super U, urea, urea plus

Agrotain, ESN and ammonium nitrate were

tested. The check did not have any nitrogen

applied.

The Effect of Different Nitrogen Application Timings on Corn Yield

Objective

The objective was to measure the

effect of different nitrogen fertilizer rates on

corn yield.

Nitrogen fertilizer rates are based on yield

goals and contributions of nitrogen from

various sources.

Nitrogen efficiency is affected by

uncontrollable factors such as precipitation

and temperature. Controllable factors are crop

type, past crop, yield goals, organic matter,

application timing and sources of nitrogen.

These factors should be carefully considered

when modifying nitrogen application rates.

Methods & Materials

Ammonium nitrate was used as a pre-

plant nitrogen source.

Previous Crop: Soybean

Variety: Pioneer 1395HR

No. of replications: 5

Results and Discussion

The 2011 growing season had little

loss of nitrogen resulting in high yields even

at low application rates of nitrogen. This is

different from past years in which we had

losses from denitrification caused by heavy

rain events during late May and early June.

The 120 pound nitrogen rates

produced maximum yields. The yield results

are shown in the following chart. The

nitrogen rate plots located on the Heitman

Farm were flooded.

Page 17 The Value of Narrow Row Spacing with a

June Soybean Planting Date

Objective

The objective was to demonstrate the

yield advantage of 15-inch row spacing

compared to 30-inch when seeding later

planted soybeans. The Extension Service

recommends using narrow row spacing during

delayed planting. When planting late, the time

for vegetative growth is shorter and this

reduces the canopy development. By

narrowing the row spacing, the crop can

compensate by producing more pods per area.

Methods & Materials

Ten foot wide plots were planted and

the center rows were harvested. Each variety

was an individual test comparing the 30-inch

row spacing with 15-inch.

Previous Crop: Corn

Variety: Various

Results and Discussion

Each variety was a single experiment

that compared 30-inch row spacing to 15-inch.

The chart compares each variety with a 30-

inch row spacing to the 15-inch. The means

are provided at the top of the bar. Each variety

performed better in narrow rows compared to

wider rows in the June 6 planting date.

Page 22 FFA Student Field Day

Two hundred fifty four high school

students from 8 area schools attended the

annual Student Field Day at the Graves-

Chapple Research Center on September 16.

The goal for the event is to show some of the

various aspects of agriculture to demonstrate

to our youth that there is more to agriculture

than planting crops.

Each learning station was designed to

provide hands on learning opportunities for

the students on some of the cutting edge

technology and practices used in today’s

agriculture and how it affects their everyday

lives.

The learning stations were:

1) Is Ugly Only Skin-deep? The Relationship

Between Log and Lumber Defects - Using

a portable sawmill they demonstrate why

some timber is more valuable for wood.

2) Representative from MU with

opportunities in ag at MU

3) Conducting an Energy Audit - With the

rising

cost of energy, the need for and how to

conduct energy audits.

4) Precision Ag - How the use of technology

can reduce input cost, maximize yield and

make producers more efficient.

5) Wind and Solar Energy - As energy costs

increase, more people are looking at

installing alternative energy sources to

generate their own electricity.

6) Composting/vermiculture – Composting

can help reduce the materials added to

landfills and produce a valuable product.

7) Biomass Energy Production - The

Renewable Energy Standards of 2006

make the production of ethanol from

biomass a mandate.

8) Turf grass Management - One of the

fastest growing industries is the care of

turf grass in both lawns and public spaces.

9) GPS and Community Resource Mapping -

How the use of handheld GPS devices can

be a useful tool for people in urban

settings.

10) Field tour to show some of the projects

and research being conducted at the farm.

A lunch of hotdogs and hamburgers

was provided by the research center and local

area businesses and prepared by the Rock Port

Rotary club. Volunteers from the Atchison

County Extension council helped serve the

meal.

Assignments were given to each class

to do a simple energy assessment of their

farms and/or homes in order to evaluate what

the students learned at the field day. They

were asked to identify energy saving

Dr. Brad Fresenburg, Assistant Extension

Professor and turf grass specialist explains

some of the differences in varieties using the

turf grass plots at the Graves-Chapple

Research Center.

Handheld GPS devices can benefit us in

everyday life according to Charlie Ellis,

MU Extension Natural Resource Engineer.

opportunities and to list the energy saving

changes they and their parents were likely to

install as a result of their assessment.

Many of the students identified

changing light bulbs as an opportunity for

saving energy. Others identified changing to

Energy Star appliances, turning off lights, and

alternative fuels. Some said they would raise

the temperature in the home in the summer

and lower it in the winter.

Students were asked to rate their

knowledge on four subjects before and after

the field day using the following scale: No

knowledge, Some knowledge, Average

knowledge, Above average knowledge,

Excellent knowledge

1) Why energy conservation is important.

Before the field day averaged 3.2

After averaged 4.5.

2) Knowledge of increasing energy

efficiency on farms.

Before the field day averaged 2.4

After averaged 4.1.

3) Knowledge of how to calculate energy

savings and simple payback.

Before the field day averaged 1.65

After averaged 3.4.

4) Knowledge of sources of energy assistance

Before the field day averaged 2.5

After averaged 4.1.

From these figures, the attendees

increased their knowledge on all the subjects

as a result of the presentations made at the

field day.

The Department of Energy developed

metrics for farm energy field days. Based on

these metrics we would expect energy saving

from this field day of 12936 million Btu’s of

energy. There would be a reduction of 235

metric tons of carbon. Electricity reduction

would be 726 megawatts and reduction of

6759 gallons of propane use would be

achieved.

Kent Shannon, MU Extension Natural

Resource Engineer, demonstrates how GPS

benefits producers in todays agriculture.

With Bob Chapple and Wayne Flanary as

their guides, a group of students sets out on

a tour of the research and demonstration

plots at Graves-Chapple Research Center

Demonstrating how composting naturally

or using worms to break down materials

can reduce landfill wastes and provide a

useful product is MU Extension Regional

Horticulturalist Tom Fowler.
