Milo or Sorghum – What Say You?

I was recently asked by David Ocker (@davidocker286 on Twitter), “Where did the nickname for sorghum, “milo,” originate?”

While there are several sources that can enlighten us on the history of sorghum and its relatives, I thought this excerpt taken from the book, Crop Production – Evolution, History and Technology by C. Wayne Smith ( Wiley & Sons, Inc., 1995), provided valuable insight on how various sorghum types, including milo, came into production in the United States.

“The first grain sorghum introduced into the New World came by way of slaves imported from West Africa. These introductions were probably used as ship’s stores (food supply for consumption during the trip) for the voyage across the Atlantic. These were probably race guinea and became known as guinea corn and chicken corn. Although grain sorghum is a major food crop in much of the world, and indeed was domesticated as such, the fact that its first introduction into present-day United States was as a food for slaves probably destined it to become established as a food for the poor only and consequently found use predominately as a feed grain in the United States. The term chicken corn may denote that it was quickly established as a corn (feed grain) of appropriate size for chickens. At any rate, grain sorghum is today a feed grain in this country, while being a major food grain in most other countries where it is produced. It also is reasonable to assume that, since the industrialization of the food industry took place in the the northern tier of states, wheat and corn would predominate research and equipment development to the exclusion of grain sorghum, a regional crop of the South only used for feed. This same phenomenon occurs today with the major food companies ignoring gossypol-free cottonseed, which has protein quantity and quality for human consumption superior to many other seed crops.

Deliberate introduction of sorghum began in 1857 with the importation of a “sorgo” type used for the production of syrup. These are referred to today as cane sorghum, sweet sorghum or cane, not to be confused with sugar cane. In that year, seed of Chinese Sugarcane, a sorgo or syrup sorghum, was sent to Texas by the U.S. Indian Service for production in the Brazos and Comanche Amerindian reservations. Additional early introductions were:

  • 1874: Brown and white seeded durras called “gyp” corn, as they were falsely believed to have originated in Egyt;
  • 1876: Kafir type from South Africa:
  • 1880: Milo, milo maize, or giant milo: race and origin unknown;
  • 1890: Shallu, a guinea-kafir intermediate from India:
  • 1906-8: Feterita, race caudatum, or intermediate race durra-caudatum, from Sudan;
  • 1906-8: Hegari type, race dauatum, from Sudan; and
  • 1906-8: Pink kafir from South Africa.

All of the early sorghums were for forage or were dual-purpose – i.e., they were grazed, baled, and/or seed harvested as feed. Early farmers in the more arid plains of Oklahoma and Texas quickly realized the difficulty and uncertainty of producing corn as a feed for work animals and turned to the more drought-tolerant grain sorghum. The Texas Agricultural Experiment Station Bulletin No. 13 published in 1890 reported 23 varieties (i.e., cultivars) of sorghum available to Texas producers. That publication noted that farmers valued both the stalk and grain as feed stuffs. The need for more drought-tolerant crops in the arid plain states resulted in the majority of early plant improvement in grain sorghum being accomplished in Texas, Oklahoma, and Kansas.

The early sorghums in the United States were tall-growing and late-maturing, facts that we will return to subsequently. But the milo maize introduction of 1880, later referred to as Giant Milo, spread to Texas by 1890 and was particularly tall-growing. In fact, the common Texas folk tale of this sorghum was that it took a ladder to reach the head, an axe to cut the stalk, and a grubbing hoe to uproot the stubble. Seed of tall sorghums of that time were harvested by a person standing on a mule-pulled wagon to cut off heads and then of course accumulate the heads in the wagon for transport.

Shortly after the turn of the century, farmers found early-maturing heads of Giant Milo, which gave rise to a cultivar called Standard Milo. (Note that much of the literature will use the term “milo” to refer to grain sorghum of the durra race. Much of this race is characterized by a recurved peduncle such that the head is upside down at maturity.) Also about 1900, a farmer in Oklahoma selected Dwarf Yellow Milo from Standard Milo, seed of which were purchased by A B. Conner for the U.S. Department of Agriculture (USDA) and distributed to farmers in north Texas near the town of Chillicothe. The distribution probably occurred between 1905 and 1910, as the Texas Agricultural Experiment Station and the USDA began research efforts at Chillicothe in 1905. An earlier-maturing cultivar, Early White Milo, was selected from the yellow milos about 1910.”

So, did this excerpt really answer the question on where the name “milo” came from? I think given that milo was a type of sorghum introduced and cultivated throughout the United States since 1880, it stands to reason that the name carried over through the generations. At least in my travels throughout the south and Great Plains regions, milo and sorghum are used interchangeably. And given that a high percentage of it is for grain production, I understand both to mean the same. Perhaps other regions of North America call it something different?

In today’s world of grain production, varieties of sorghum other than the standard grain sorghums sold by the major seed companies are generally grown and sold by heirloom seed providers. Scouring the web, it’s easy to find providers of kafir, sweet sorghum and other old world varieties. You’ll often find old cane presses being demonstrated at country fairs and antique farming shows.

(If the reader is curious about the etymological origin of milo, look no further. The answer to that question lies here in the online American Heritage Dictionary: https://ahdictionary.com/word/search.html?q=milo.)

I want you to do well.

2020-21 Pioneer Hi-Bred Seed Catalog

It may not have the same feeling as the arrival of the Sears Catalog back in the old days, but the 2020-21 Pioneer Hi-Bred catalog has just been published. Different from yesteryear, this catalog comes to you digitally – as a PDF file. The print version will still be available for those that prefer to sit down at the kitchen table with a cup of coffee and a pair of reader glasses and leisurely browse through the newest hybrids and varieties. The PDF version provided below is great for use on smart devices where you can zoom in to see the small print and digitally “flip” through the pages. (Note: this catalog version is for South, Central and North Texas and Oklahoma.)

A sea of Pioneer Hi-Bred sorghum. Sorghum prices are up! Prepared to plant more?

I know, having a seed catalog available in August seems early. The thing is, for those of us further to the south, planting begins as early as January and grain harvest is nearly over by August. So, with plot results and field data fresh at hand, reviewing and talking about what to plant next year in late August and September is not unreasonable.

Nearly everything is here in this catalog – Corn (grain and silage), soybeans, sorghum (grain and forage), alfalfa, sunflowers, inoculants and seed treatments. Even the major crop protection products offered by Corteva Agriscience are included. Twenty pages of full bliss from an all-American company!

Side-by-side plots are the best sources for hybrid comparison data.

For students of salesmanship and marketing, I encourage you to compare the 2020 catalog to the 1946 catalog that I highlighted a few blogs ago. The formatting, photos, vernacular, etc. are quite different. Publishing styles and technologies have certainly changed over nearly 75 years – along with prices and yield.

It won’t be long before your sales representative visits again. Study the new catalog before he or she arrives. Be prepared – have your farm data available with field by field summaries if possible. Yield data from local plots may also be helpful and can be viewed at Pioneer.com (no, we don’t win them all). And don’t be afraid to ask for input from the Pioneer agronomist. Rumor has it that they’re very knowledgeable.

Please Focus!

After six years and 5,000+ followers on Twitter (of which one-fourth were women and bots who mistakenly thought agronomists were wealthy), and a change in job responsibilities, I decided it was time to refocus my energies on social media. Frankly, I wanted to separate personal life from work and give others an opportunity to step up and take the lead on providing agronomic expertise for the growers. Too, as followers grew, I found myself spending entirely too much time muting and blocking folks that were basically trolling, getting threads completely off target and otherwise wasting my time. So I shut down my main Twitter account (@texasagronomo), set up a new one for my woodworking hobby (@tejaswoodworker) and set about refocusing my role on social media platforms.


A fresh account and a fresh focus on Pioneer Hi-Bred and agronomy.

So we start anew with @Pioneeragronomo in a new job role – that as Product Agronomist covering from Oklahoma to the Rio Grande Valley. This account will continue to support Pioneer Hi-Bred (@PioneerSeeds) and Corteva AgriScience (@CortevaUS) and will focus only on agronomy. Nothing else. And, based on previous experience, I will be quicker to mute or block the drama queens and non-believers in Pioneer genetics and won’t bat an eye or lose a second of sleep in doing so.

Hail – Hell on Crops

They’re violent, loud, dangerous, destructive and often are precursors to tornadoes. Hail storms. The average hail storm lasts less than a couple of minutes but depending on the intensity and size of hail stones, damage can vary from barely noticeable to total crop destruction.

A healthy and complete crop canopy provides the highest yield potential for growers.

Hail damage to crops basically comes down to these questions – will the plants survive and, if so, will yield be affected? In my experience, more so for corn, the most noticeable effects of hail damage are three-fold: twisting of the leaf canopy, leaf loss, and stem bruising.

Twisting of the leaf canopy is the result of leaves being shredded by hail stones with the shredded remnants being wrapped or twisted by excessively strong winds. (This phenomenon is more prevalent in young corn, usually V6 or smaller.) The reason this can impact plant survival is that the newly emerging leaves in the whorl can’t advance as the plant recovers. Survival rates of plants can improve if the dying, twisted leaves can somehow detach from the plant, making emergence of the new leaves possible. The impact on yield depends on plant death (stand loss) and distribution down the rows (plants that recover quicker can shade out and out-compete adjacent plants.)

Leaf loss is the most obvious effect of hail on plants. The leaves are the photosynthetic factory – capturing sunlight and converting it to energy that supports plant growth. Believe it or not, there are times when complete leaf loss will not impact yield. Such is the case in corn where leaf loss up to about V3 is not detrimental. Reason being, this is before ear development commences and the plant is still dependent on the seminal root system for support.

An excellent chart on the effects of leaf loss on corn yield can found in the University of Nebraska publication: http://extensionpublications.unl.edu/assets/pdf/ec126.pdf. This is my go-to extension publication on this subject and it includes examples of various field situations. For a discussion on hail damage effects on forage/silage quality: http://corn.agronomy.wisc.edu/Management/L039.aspx.

Whorl or stem bruising is often overlooked in assessing hail damage. Hail stones are dense and hard. Young corn plants, however, are tender – very little lignin formation has occurred and so a somewhat rigid stalk rind has yet to develop. As the winds bend over the stalks, the lower sections are exposed and vulnerable to being struck by hail stones. The thing to remember is that the growing point is near or above the soil surface around V5 or V6. If the stone penetrates deep enough, it can bruise and kill the growing point. When this happens, the plant is finished. A sharp knife (and the appropriate protective gear) can help determine the depth of penetration of a hail stone. The growing point should be near white while a damaged or dying growing point will turn brown.

For a discussion of hail damage on young corn, I highly recommend this site, authored by Dr. Robert (Bob) Nielsen at Purdue University: https://www.agry.purdue.edu/ext/corn/news/timeless/HailDamageYoungCorn.html

As with most storm events, its too wet to do anything in the field afterwards so the best advice is to wait and assess plant recovery over a period of about a week. Give the plants time to recover! In the meantime, don’t hesitate to call your seed rep and agronomist and get their opinion. Here are some other resources for various crops:

Goodbye to a Hybrid

An Essay on the Rise and Fall of Hybrids in the Seed Business

Since the beginning of hybrid corn development in the early 1900s, breeders have made step changes in product performance.  (A step change is where the new hybrid is not just a little better than the previous generation of products but so much better that growers will demand only that hybrid.)  These changes might encompass significant improvements in disease tolerance, lodging or insect resistance and of course, yield.  Sometimes the step change is extraordinary.  The seed industry has seen this over the years where a hybrid performs at such a high level that it takes traditional breeding programs literally years, sometimes decades, to catch up to it.  Pioneer Hi-Bred has a wonderful history of these, most notable being corn hybrid Pioneer® brand 3394 (early 1990s) and sorghum hybrid Pioneer® brand 84G62 (late 1990s).

Understandably, growers can become emotionally attached to these extraordinary hybrids.  After all, their success is tied to the performance of the products they plant.  Yes, it’s mostly yield that drives this success, but not just yield in one year – yield across multiple years.  In the seed industry, we describe a hybrid that yields consistently over time and across environments as “stable.”   As an experienced agronomist with over 20 years of experience, stable hybrids are few and far between.  These are the hybrids that growers request for many years knowing that the hybrid will perform and that they won’t have to worry about whether the latest and greatest new product will let them down.  In a business that’s often “year to year,” this stability is often welcomed.  It’s peace of mind.

Unfortunately, or fortunately, depending on which side of the ledger you’re on, stability is not always the driving factor in selling hybrids.  It’s no secret that seed companies will literally introduce and drop a hybrid after only one year.  This speaks to the rapid improvements in breeding science but also the drive for yield and financial success in a very competitive market place.  So, hybrids that are stable – meaning, not always winning the yield contest but certainly above average – are not always in demand.  This makes life difficult for a seed company in deciding what to grow for the next selling season.

After harvest, a seed company must decide what hybrids to produce the following summer in order to have the seed supply needed for their customers to plant in the spring more than a year later.  To do this, they must predict what hybrids their customers will likely buy for the following year.  But growers often base their purchase decisions on the current year’s performance and don’t always consider previous years.  Weather plays a key role in product performance but no two years are alike and the best hybrid this year might not be the best next year.  As you might imagine, it’s very difficult to predict which hybrids will perform best when you don’t know what the weather will bring!  Given this, stability seems like a good thing, doesn’t it?

The complexity of growing hybrid seed is nearly overwhelming.  Below is an example of a corn hybrid that’s widely adapted (image courtesy of Pioneer Hi-Bred) that literally has 221 variations.  For this hybrid, there are nine versions of trait offerings for various market opportunities.  A few examples include a “conventional” version – no traits for the organic market; an herbicide tolerant version – no insect traits but needed for refuge acres and a below-ground insect protection version for areas with known corn rootworm pressure.  Next are seed treatments – various rates of insecticide, formulations, active ingredients, etc.  Then there are several packaging options of which the most common are boxes and bags but imagine various sizes of these units to accommodate field research needs.  My personal favorite is the last tier which is seed size – rounds and flats of which there are small, medium and large.  Depending on the hybrid, there can also be extra small and extra large.  Today’s high-tech planters can often be fickle about seed size.  Take my word for it, you can have all the right genetics, traits, seed treatments and packaging but if you don’t have the right seed size for the planter, you can lose the sale!  Seed size is mostly determined by genetics but can be manipulated to a certain degree by management.  Historically, hybrids have been dropped because they consistently produced seed that was either too small or too large.

This complexity in seed offerings for the grower has value.  A seed company is a business and assigns a cost to every one of the 221 variations in this example.  It must do this to keep track of production costs and understand what “value” each variation contributes to the overall picture.  So, what happens when a hybrid doesn’t perform to expectations and growers decide to move on?  Demand drops and now the cost of producing these variations starts to increase.  (Imagine growing seed based on demand that fizzles for one reason or another – you now have a bunch of processed seed sitting in storage that nobody wants.)   Again, this is a business.  Just as every company assigns a cost to each variation, they also assign a threshold cost where it doesn’t make sense to continue producing it.

As you observe sales of seed over time, you’ll notice that all hybrids have a “lifecycle.”  If they make the cut after the first year, sales grow for a time (they’re new and exciting), then stabilize (above-average but starting to fall behind), then drop (stable yield but just simply getting left behind by newer genetics).  Not long after the final stage, they are no longer produced.  The decision to drop a hybrid is not easy.  Typically, near the end of a hybrid’s lifecycle, production acres (the production fields where the male and female inbreds are grown to produce the hybrid seed) become more difficult to manage (small acreage needed at this point) and variability in production per acre tends to go up.  Thus, production costs also go up. 

Finally, regional differences (a hybrid does well in one area but not others) can often accelerate a product’s lifecycle.  This, honestly, is the demise of most hybrids in the industry.   When a hybrid is widely adapted –  grown on a lot of acres by a lot of producers – the production process is more efficient and frankly, more profitable.  But when demand drops quickly, as might be the case when a large growing area completely walks away from a hybrid, a decision to keep producing that hybrid must be evaluated even knowing that it might still be one of the best performers in other areas of the country. 

The seed business is complex, business-driven and very emotional.  Emotions around a hybrid can be strong as growers gain an affinity for something that feels like family.  Livelihoods thrive on the success of hybrid seed production and seed company employees often feel equally emotional at the loss of hybrids.  Given all of this, there’s an axiom about the seed business that I often share with customers: “Don’t fall in love with this hybrid. There’s a good chance it’ll be gone next year.”
