Productive but Priced Out: What the U.S./Brazil Yield Gap Really Says About Corn Seed Value

American corn growers out-yield Brazil roughly two-to-one — and pay roughly twice as much for the seed and chemistry that make it possible. A new NCGA report argues that the second ratio is no longer justified by the first.

There is a deceptively simple way to compare the value of a bag of corn seed in two countries: divide what the grower pays into what the crop returns. On a metric-ton-per-hectare basis, the United States and Brazil sit at opposite ends of the productivity spectrum, and the seed industry has historically priced accordingly. But a report released this week by the National Corn Growers Association — “Productive but Priced Out: The Input Cost Challenge Facing U.S. Corn Growers” (link) — makes the case that the price gap has drifted well beyond what the productivity gap can explain. This analysis lays out the yield picture, translates it into seed revenue per hectare, and reads the NCGA findings against that backdrop.

The yield gap: roughly two-to-one, and narrowing

USDA data tell a consistent story. For the 2025/26 marketing year, U.S. corn is estimated at a record 186.5 bushels per acre — about 11.7 metric tons per hectare — on roughly 37 million harvested hectares. Brazil, producing an estimated 138 million tonnes on about 22.8 million hectares, averages close to 6.0 t/ha. That places the U.S. national yield at nearly double Brazil’s, a ratio that has held for a decade even as both countries have pushed yields higher.

The long view matters for interpretation. In the mid-1990s the U.S. out-yielded Brazil by more than three-to-one. Brazil has since roughly tripled its yield — from under 2 t/ha to about 6 — while the U.S. climbed from roughly 7.5 to 11.7. The gap is closing, and the reason is structural: Brazil’s national average blends a smaller full-season first crop with the dominant safrinha (second crop), planted after soybeans on the same ground and grown through the drier back half of the season with lighter inputs. The safrinha is now roughly three-quarters of Brazilian output, and it is precisely where modern genetics and traits are being adopted fastest. Brazil’s best first-crop regions in the south already yield 8–9 t/ha — much closer to U.S. levels than the national average suggests.

From yield to seed revenue per hectare

If seed were priced purely to the productivity it unlocks, seed spend per hectare in the two countries would track the yield ratio. Remarkably, it nearly does. The 2026 University of Illinois (farmdoc) crop budgets put corn seed at $132 per acre — about $326 per hectare — on high-productivity central Illinois ground targeting 230 bushels. In Mato Grosso, Brazil’s largest corn state, IMEA’s 2025/26 safrinha budget puts seed at R$777 per hectare, roughly $155 at prevailing exchange rates. That is a U.S.-to-Brazil ratio of just over 2:1 — almost exactly mirroring the ~1.9× yield gap.

Two wrinkles keep this from being a clean apples-to-apples read. First, seeding rates differ substantially — U.S. growers drop roughly 85–90 thousand seeds per hectare versus 55–65 thousand in the safrinha — so on a per-seed or per-bag basis, Brazilian prices sit closer to U.S. levels than the per-hectare totals imply. Second, the per-hectare frame understates Brazil’s value to the seed industry: the same hectare sells a soybean unit and a corn bag in a single year, safrinha area is still expanding while U.S. corn area is mature, and trait-royalty capture in Brazil has improved markedly. The headline, though, holds: U.S. growers spend about twice as much on corn seed per hectare, and they harvest about twice the yield.

The NCGA report: when the price gap outruns the value gap

That rough parity between the seed-spend ratio and the yield ratio is exactly the equilibrium the NCGA’s new report argues is breaking down — not so much in seed alone as across the whole input basket. Prepared with the agricultural data firm Kynetec and released this week, the report compares 2023–2025 U.S. and Brazilian prices for the same crop inputs and finds the U.S. paying a persistent premium that, in the association’s view, “is simply too clear to ignore.”

The seed figure is the one that speaks directly to the yield analysis above. A 68% U.S. seed premium is, on its own, defensible against a ~90% yield advantage — seed priced to value should command more where it delivers more. The NCGA’s concern is that the crop-protection gaps have no comparable productivity justification: insecticides run 87% higher, herbicides approach double, and some fungicides cost more than twice the Brazilian price. Glyphosate — a decades-old, off-patent molecule — was still 35% more expensive in the U.S. in 2025. Chemistry that is chemically identical across the two markets should not, the report argues, diverge this far on price.

NCGA attributes much of the spread to market structure rather than pure economics. Brazilian growers enjoy broader access to generic and single-active-ingredient products, while U.S. farmers more often buy premium pre-mixes from a consolidated set of major manufacturers. Currency movements explain part of the gap, the analysis concedes, but not all of it — even matched active ingredients show “notable price differences.” Chief Economist Krista Swanson framed the stakes plainly: “We’re producing the same global commodity that’s largely sold at the same global price. When we’re at a disadvantage in terms of the costs to produce it… it becomes very difficult for U.S. farmers to remain competitive over the long term.”

Why it bites now

The timing sharpens the message. USDA projects 2026 corn production costs near $917 per acre while the season-average price has fallen roughly 37% from its 2022–23 peak of about $6.54 to an expected $4.10 per bushel — pointing to a fourth consecutive year of grower losses, with some budgets showing red ink near $100 per acre. Since 2007, NCGA notes, seed costs are up about 135%, chemicals about 117%, and fertilizer about 74%. A June Purdue survey found 47% of farmers naming high input prices as their top concern. NCGA President Jed Bower did not mince words: “These are scary numbers, and it’s not just corn.”

The productivity that makes U.S. corn the envy of the world is, in this framing, also what makes the squeeze so acute. High yields demand a high-input system — elite genetics, full trait stacks, and premium chemistry applied at rate — and when the price of that system runs ahead of the yield advantage it buys, the most productive growers on earth can still be, in the report’s phrase, priced out.

What NCGA is asking for

●       Greater pricing transparency from input suppliers, and pricing that reflects current farm-economic conditions.

●       Preserved access to generic and single-active-ingredient crop-protection products, including opposition to countervailing-duty petitions on imported glyphosate.

●       A legislative remedy to the countervailing-duty process, requiring trade authorities to weigh the public interest before imposing duties.

●       Federal engagement on competition — FTC scrutiny of anticompetitive behavior and USDA’s new dedicated input-price economist — plus parity on market access, including for ethanol.
 

Bottom line
 

On a metric-ton-per-hectare basis, the U.S. out-yields Brazil by nearly two-to-one, and U.S. corn seed costs about twice as much per hectare — a rough symmetry that is exactly what value-based seed pricing predicts. The NCGA’s contribution is to show that the symmetry stops at the seed bag. Across insecticides, herbicides, and fungicides, U.S. growers pay premiums of 87% to more than 200% for products that carry no comparable yield story and, in the case of off-patent molecules, are functionally identical to what Brazilian farmers buy for far less. In a stretch of sub-break-even corn prices, that is the gap the association wants explained — and closed.
