Wheat Harvest and Double Crop Considerations for 2024

Originally Published in the C.O.R.N. Newsletter

Authors: Laura Lindsey, Osler Ortez

Winter wheat maturation is about 10-14 days ahead of normal with harvest beginning late last week in southern Ohio. Last year, winter wheat yield was extremely high with a state average of 90 bu./acre (USDA NASS, 2024). During the previous five years, the state average wheat yield ranged from 56 to 85 bu./acre (average of 73 bu./acre). Last year, we attributed high yields to low rainfall (and consequently low disease) and cool temperatures, leading to a long grain-fill period. This year, we’ve experienced warmer temperatures, greater disease, and shorter grain-fill periods. Between March 1 and June 16, 2024, there were 1,000, 1,135, and 912 growing degree days at the Northwest Agricultural Research Station, Western Agricultural Research Station, and Wooster Campus, respectively (Table 1). During the same time period last year, there were 738, 816, and 617 growing degree days at the Northwest Agricultural Research Station, Western Agricultural Research Station, and Wooster Campus, respectively.

This year, wheat yield will likely be lower than last year. However, earlier wheat harvest opens opportunities for a second crop following wheat. In Ohio, double-crop soybeans are the most common crop after wheat harvest, but other crops, such as sunflower, may be planted. The two primary requirements for successful double cropping are: 1) There must be time for the production of a second crop, and 2) There must be adequate water to produce two crops, whether from stored soil moisture, rainfall, or irrigation. The first requirement will likely be met, with earlier wheat harvest and a predicted later first freeze date, but continued dry weather in areas of the state may be problematic. However, several management practices will help maximize double crop yield potential.

Double crop soybean management considerations.

  1. Soybean relative maturity. Relative maturity (RM) has little effect on yield when soybeans are planted during the first three weeks of May. However, the effect of RM can be larger for late plantings. When planting soybean late, the latest maturing variety that will reach physiological maturity before the first killing frost is recommended. This is to allow the soybean plants to grow vegetatively as long as possible to produce nodes where pods can form before vegetative growth is slowed due to flowering and pod formation.

  1. Row spacing. Double-crop soybeans should be produced in narrow rows- 7.5 or 15-inch row spacing. The later soybeans are planted, the greater the yield increase due to narrow rows. Soybeans grown in narrow rows produce more grain because they capture more sunlight energy, which drives photosynthesis.
  1. Seeding rate. Soybean plant population at harvest for mid-to-late June plantings should be between 130,000-150,000 plants/acre. The harvest population for early July plantings should be greater than 180,000 plants/acre. Harvest population is a function of seeding rate, quality of the planter operation, and seed germination percentage and depends on such things as soil moisture condition, seed-soil contact, and disease pressure.

Double-crop sunflower management considerations.

In addition to double cropping with soybean, other alternatives may become feasible within the crop system. In 2022-2023, field experiments were established to study sunflowers’ viability as a double crop after wheat or barley harvest in Ohio (Figure 2).

Figure 2. Double crop agronomic sunflowers planted at 30-inch row spacing after wheat harvest during 2022-2023 field projects in Ohio.

The study had three commercial high oleic sunflower varieties: “ultra-early” maturity (N4H161 CL), “early” maturity (N4H302 E), and “mid-early” maturity (CP 455 E). These varieties were studied across three seeding rates: 17,000 seeds per Acre, 22,000 seeds per Acre, and 27,000 seeds per Acre. Preliminary results showed sunflower yields ranging between 1,012 lbs./Ac and 2,740 lbs./Ac (Table 3). The average yields per site were in the 1,400 to 1,900 lbs./Ac range, with the two highest yield sites being comparable to the average U.S. sunflower seed yields in the past two years.

From the preliminary results on the sunflower work, crop production challenges have included weather, equipment availability, bird damage, plant lodging, and variable/low stand counts which have possibly limiting crop yields. This project is in progress and will be planted again in 2024, more results are forthcoming. Future considerations for sunflowers should include consistency of results across sites/years, variety selection, seeding rate, germination, fertility, bird control, seed/oil quality, and marketing options as major priorities.

Beef with a Business Mindset

– Haley Shoemaker, OSU Extension AGNR Educator, Columbiana and Mahoning Counties (originally published in the Ohio Farmer on-line ; sourced from the Ohio Beef Cattle Letter)

These days dropping a cull or feeder calf off at the local auction can feel a little bit like Christmas in July – prices are solid, and markets are strong, largely due to a decline in cattle inventory following years of drought and

Find out where your ‘benchmarks’ fit among your peers.

production challenges.  And while as cattle producers we’re naturally inclined to keep the “when will these prices end” thought in the back of our mind, we also sometimes find ourselves getting comfortable with the idea of $135/cwt for culls or upwards of $300/cwt for calves.

Periods of high prices, such as those the industry is experiencing now, have been known to make the good farm business manager look great, and the mediocre farm manager look good.  Anyone who’s been in business for any amount of time knows that these trends have a way of evening themselves out, but the factor that remains is that a well-managed farm business will stand the test of time, and volatile markets.  One of the tools utilized by beef herd managers across the U.S. is called FINPACK, a financial analysis software service offered in Ohio through the Farm Business Analysis and Benchmarking Team.  Each year, farm analysis teams throughout the country collect data from a variety of enterprises, ranging from beef, dairy, and crops to specialty products and small ruminants.  The data collected from balance sheets, income statements, and enterprise analyses not only provide invaluable information to the producer and their operation, but also compile the national database, known as “FINBIN”, managed by the University of Minnesota.

Taking a look at FINBIN’s five-year financial report for beef cow-calf enterprises, a couple trends stick out – net return, an indicator of the farm’s profitability, has only recently climbed into the positive during 2023 at an average of $125.31 per cow, preceded by four years ranging between ($41.50) and ($113.13) per cow.  2023’s rise in net return was accompanied by increased direct and overhead expenses, totaling $1,019.85 per head on average, indicating that even with elevated feed and operating costs, managers who took a calculated approach to business decisions “made the most” so to speak, of a favorable marketing landscape.  Those producers who managed their way into the top 20% of beef herds included in the 2023 database saw an average net return of $564.09 per cow, and an average of $812.14 per cow in direct and overhead expenses.  This represents a nearly $438 break separating the “average” and “top” herds, which can be the difference between a profit or loss during a year of weaker markets.

So, how do you know where your farm falls?  Is your business average, slightly above, or excelling – and how does your operation measure financial success?  If “I don’t know” was the answer to any of those questions, completing a farm business analysis may be a logical next step.  Beginning a financial analysis can be an eye-opening experience for a farm business.  In addition to gaining perspective on how a farm compares to similar operations throughout the state, producers also learn how to keep more targeted and detailed records, allowing for historical data and trends to be identified over years of participation in the program.  These trends provide insight into the operations’ reaction to business decisions and market variability, and can help producers clearly decipher financial strengths, areas of potential concern, and opportunities for improvement.

Producers throughout Ohio have the option of completing either a whole farm analysis, or whole farm with enterprise analysis.  Both provide individualized reports that take into account beginning and ending balance sheets and income statements, however those who complete an enterprise analysis will also receive summaries breaking down costs of production per unit (per head, cwt, acre, etc.).  All data is handled with care to preserve confidentiality.  Additionally, personalized benchmark reports serve as a useful tool in visualizing an operations percentile ranking among peers, which has often been stated as one of the most beneficial outputs of completing a farm business analysis.

Getting started is as simple as reaching out to your county Agriculture and Natural Resources Educator, or to Clint Schroeder, Program Manager, at 567-242-6693 or via email at schroeder.307@osu.edu.  It’s tempting during times of favorable prices to shift resources and attention to putting out the next most demanding fire, but recent history has proven that consistent, diligent management is what prepares a farm for years where financial efficiency matters most.  In the long run, you can’t manage what you don’t measure – don’t let your financial success fall into that category.

Growing Degree Day (GDD) Summary, May 2024

Authors: Amy Stone
Published on:

The Plant Phenology and Growing Degree Day (GDD) posts and impacts have been a Buckeye Yard and Garden onLine (BYGL) staple for years. GDD will continue to be an important part of the blog written to assist green industry professionals, Extension professionals, Extension volunteers, and people with a passion for plants and pests too.

Readers will continue to see those updates in the BYGL on a monthly basis, but there is no better way to track GDD and ultimately the plant blooms and insect activity on your own. Be sure to save this website ( https://weather.cfaes.osu.edu/gdd/default.asp ) as a favorite, and set those calendar reminders now to check the website regularly.

Here is a Growing Degree Day Refresher if GDD is new, or you need a little review!

GDD are a measurement of the growth and development of plants and insects during the growing season. Development does not occur at this time unless the temperature is above a minimum threshold value (base temperature). The base temperature varies for different organisms. It is determined through research and experimentation. The actual temperature experienced by an organism is influenced by several factors. These factors affect growth and development. For instance, depending on the weather, an organism’s temperature may be a few degrees more or less than that recorded. An organism may spend its time in the shade or under direct sunlight. The fertility and nutrient content of the soil directly affect the growth rate of plants and thereby indirectly influence insect growth rates. The presence of weeds and precipitation may indirectly influence development. Due to these factors and some other scientific considerations, a base temperature of 50 degrees Fahrenheit is considered acceptable for all plants and insects. (Source: OSU Plant Phenology Website)

The one thing that we do know is that the sequence of events – both plant and pest development – consistently occurs in the same order no matter the weather.

At the end of each month this calendar year, there will be a GDD Summary Alert Posted to BYGL. While today’s post has some areas seeing zeros – it is the start of the calendar year – we will have to see if that is true. As you can see below, 21 Ohio locations (City, County, and Zip Code) have been chosen across the state and will continue to be used for the monthly updates.

Crop Response to Phosphorus Fertilizer in Ohio

Authors: Dr. Manbir Rakkar, Greg LaBarge, CPAg/CCA; Original published in the C.O.R.N. Newsletter

Phosphorus (P) is an essential plant nutrient and P fertilizers are added to supplement the soil’s available P. There are economic and environmental benefits to making informed decisions about P fertilizer use. The under-application of P fertilizer can result in reduced yields, while over-application adds to input costs, with economic losses resulting from both scenarios. From an environmental perspective, excessive P going into streams and lakes can result in toxic algal blooms.Young Corn Plants

A few frequent questions about P fertilizer use are: Does P fertilizer always result in a positive yield response? How much yield increase is expected with applied P? What is the likelihood of yield penalty if P fertilizer is not applied?

A recently published factsheet‘Soil Phosphorus and Crop Response to Phosphorus Fertilizer in Ohio’ (https://ohioline.osu.edu/factsheet/anr-0146), provides a general overview of soil P and highlights the findings of Culman et al. (2023) to answer these practical questions (Rakkar and LaBarge, 2024). The study summarized 457 replicated field P trials conducted over the last 45 years across 40 counties in Ohio. The robust dataset evaluated corn, soybean, and wheat response to added P fertilizer in trials conducted on farms and at research stations.

Below are some key takeaways:

Does P fertilizer always result in a positive yield response?

No. Out of the 457 field P trials, a significant increase in crop yield was observed in 107 trials with P application. The crop response to added P also varied among crop types. Corn responded to P application in 29.9% of trials, soybean in 14.2%, and wheat in 36.8% (Fig. 1).

Fig. 1. Relation of relative yield and soil Mehlich-3 P for corn, soybean, and wheat across 457 field trials

Fig. 1. Relation of relative yield and soil Mehlich-3 P for corn, soybean, and wheat across 457 field trials (Culman et al., 2023).

How much yield increase is expected with applied P?

It depends on the Mehlich-3 soil test P level. The Mehlich-3 soil P measures the readily available soil P for crop uptake. Culman et al. (2023) classified Mehlich-3 soil P levels into five categories: <10, 10–20, 20–30, 30–40, and >40 ppm to evaluate the yield increase for each soil P category.

The crop yields were presented as Relative Yield, which refers to the yield with no P application divided by the maximum yield obtained across all P treatments. In other words, 100% relative yield means no yield increment with added P. The lower the relative yield, the higher the yield increment.

Generally, as the soil test P levels decreased, the yield increment increased with P input (Table 1). When the soil test P was less than 10 ppm, the median relative yield was 87%. As the soil test P level increased above the critical level of 20 ppm, the median relative yield ranged from 97% to 99%, signifying minimal yield increment with added P.

What is the likelihood of yield penalty if P fertilizer is not applied?

We can also determine the likelihood of yield penalty based on Mehlich-3 soil P with the information in Table 1. When the soil P level was less than 10 ppm, 67% of trials showed increased crop yields with applied P. When the P levels were above the critical level of 20 ppm, only 12-14% of trials showed increased crop yields. In other words, the likelihood of yield penalty with no P application decreases as soil P levels go above 20 ppm. If the soil test P level is less than 20 ppm, there is an increased risk of yield penalty with no P application.

A Minimalist Approach to Ensuring Fall through Spring Vegetable Harvests

– Matt Kleinhez, Article Originally Posted on Fruit, Vegetable, & Specialty Crop News)

Interest in marketing locally-grown, freshly-harvested vegetables fall through spring is strong and increasing among high tunnel growers in the Midwest, Great Lakes, Mid-Atlantic, Mid-South, and Northeast. Scanning the agendas of industry meetings and listening to growers and others in these areas makes clear that fall through spring harvest and marketing of high tunnel-grown crops is an established and increasingly common practice. Importantly, some growers have transitioned to cash cropping their high tunnels only fall through spring and leaving summer to grow cover crops and focus on other priorities, including field-based production. Conversations with and public presentations by these growers and other experts make clear that fall through spring income from high tunnel production can be significant if the correct crops and varieties are chosen and suitable practices are used.

We have long wondered which crops, varieties, and practices may be ideal for Ohio high tunnel growers looking to harvest fall through spring. Much of our previous research focused on a relatively small number of crops and the use of various tools and practices (e.g., films, fabrics, and/or soil heating). Our goal was to describe potential production outcomes when high tunnel growers invested in the process to various levels. Results from those experiments suggest that yields are likely to be greatest when investments are also highest, for example, when soil heating, plastic films, and row covers and the effort to maximize their utility are used. Those studies were summarized previously in this blog.

We are asking a different question in Winter 2023-2024. As the three panels below describe, seven crops were seeded in two high tunnels in October-2023 and grown without any supplemental heating, films, or row covers. This “minimalist” approach explores the worst-case scenario, the minimum that can be expected from these crops under the conditions they have experienced since seeding. This approach may appeal to growers unfamiliar with fall through spring production and/or those who are unwilling or unable to invest much time, money, or effort in it, at least at this time. The test outlined below is one example of what can be expected but many others exist. Of course, different outcomes may be possible when other varieties, planting dates, and growing practices are used. Upcoming evaluations will push the “minimalist” approach further as all crops capable of being grown and harvested fall through spring do not require a high tunnel.

Tips to Stretch Short Hay Supplies

– Dr. Jeff Lehmkuhler, PhD, PAS, Beef Extension Professor, University of Kentucky

Below are a few tips to consider stretching limited hay supplies. For additional information contact your local Extension agent. It is recommended to consult with your feed nutritionist or County ANR Agent before making drastic changes in your feeding program.

  1. Inventory hay – know how much hay you have available; weigh a few bales to get an average weight or estimate the weights based on available information from Extension publications.
  2. Minimize storage losses – keep hay off the ground on a surface that will allow water to drain away; keep bales covered or stored inside a barn; if bale grazing limit the number of bales placed in the field to provide 2-4 weeks of feeding to reduce weathering losses.
  3. Reduce feeding loss – consider minimizing feeding losses; using hay rings with skirts / metal on the bottom, tapered ring designs, chains to suspend bales, or cone inserts to keep hay inside the feeder has been proven to reduce hay feeding losses compared to hay rings with openings at the bottom; using an electrified temporary poly-wire placed down the center of unrolled hay will reduce losses from cows laying on the hay, trampling it into the mud, and defecating on the hay; feeding processed hay into a bunk or large industrial tire reduces waste compared to feeding processed hay on the ground.
  4. Cull – consider selling less productive females, open cows, and cows with structural/functional issues to reduce the number you must over winter; consider selling the bull as the market may provide the opportunity to sell a mature bull and replace him with a younger bull next spring.
  5. Limit time access to hay – research has shown dry cows in mid-gestation can be maintained on good quality hay when they have restricted access time to only 6-8 hours a day; the hay savings comes from less waste as feeding behavior is altered; all cows must be able to access hay at any given time; this is not recommended young or thin cows, lactating cows or growing animals.
  6. Substitute hay with grain – calories and protein can be provided from supplements; grain/commodity mixes can be used to replace hay; cows can be maintained on a low hay diet by using grain supplementation that balances the nutrient supply and animal requirements; consult a nutritionist before making extreme feeding changes.
  7. Deworm young animals – animals with an internal parasite burden will have reduced efficiency.
  8. Feed an ionophore – if grain supplementation will be used, consider adding an ionophore to increase the energy efficiency of the feed consumed. Consult your nutritionist to discuss inclusion rates and developing a supplement program. Previous work has shown that feeding 200 mg of monensin allowed cows to maintain body condition on 10-15% less hay.
