State-by-state crop yield data for US row crops
Corn, soybeans, wheat, cotton, and sorghum yields straight from USDA NASS — how your state compares to the national average, 6-year trends, and what closing the gap could be worth with precision ag.
Checked against USDA NASS on Oct 13, 2026 · Latest corn yield: 2026 Oct forecast · Last data change published: Oct 12, 2026
A national yield average flattens away the exact thing a farmer needs to know: whether their own operation is ahead of or behind the states growing under similar conditions. Irrigated corn in Washington and dryland corn in Kansas both feed into the same national number, but they run on completely different cost structures and yield ceilings — comparing your farm to the national average tells you almost nothing useful.
Comparing it to your own state's multi-year trend, and to states with similar rainfall and soil, tells you where the real opportunity is. We pull directly from the USDA NASS Quick Stats API, so the numbers match what's published in the Crop Production report — no third-party smoothing or estimation — and they refresh automatically whenever NASS publishes a new forecast or final estimate.

Estimate payback and 3-year ROI for your farm before opening a state page.
Estimate the payback on variable-rate seeding, zone-based fertility, and overlap reduction for your farm.
Estimate only — based on industry-average implementation costs (variable-rate seeding $18/ac, zone-based fertility $22/ac, overlap reduction $9/ac; $12,000 fixed + $17/ac ongoing) and USDA yield benchmarks, not a quote. Prices: USDA NASS national price received, Aug 2026 (updated automatically).

How often is USDA crop yield data updated on GreenMatrix?
GreenMatrix checks USDA NASS every 6 hours and updates a page as soon as the underlying number changes. For corn, soybeans, cotton and sorghum, NASS forecasts state yields from August to November (Aug 1 / Sep 1 / Oct 1 / Nov 1 conditions) and sets the final figure in the Crop Production Annual Summary each January. Wheat forecasts start in May and the final wheat figures come with the Small Grains Summary at the end of September. Last check: Oct 13, 2026.
How is the "vs US average" percentage calculated?
State yield divided by the national figure for the same crop and year, minus 100%. The national average is USDA's weighted figure across all producing states, not a simple mean of state values — so it isn't distorted by a handful of small states with unusual yields. While the season is in progress, both figures come from the same USDA forecast.
Why is my state's yield below the national average — is that bad?
Not necessarily. A negative percentage usually reflects climate, water access, or soil type rather than farming quality. Irrigated states and states with longer growing seasons will structurally outperform dryland, short-season states on raw yield regardless of management. Benchmark against states with similar growing conditions, and against your own state's history, rather than the national number alone.
Why does a yield say "forecast"?
Until USDA publishes the final estimate, the current-season figure is a USDA forecast. GreenMatrix labels it with the forecast month (for example "Sep forecast") and replaces it automatically with the next forecast or the final estimate.
Where does the yield data come from — is it reliable?
From USDA NASS — the same source used by land-grant universities, farm lenders, and federal crop insurance. We don't estimate, model, or adjust anything. NASS sometimes revises historical figures; every page is re-checked against NASS at least weekly, so revisions are picked up automatically. You can always verify at nass.usda.gov.
How does the Precision Ag ROI calculator work?
It estimates the annual dollar value of closing the gap between your current yield and your state's multi-year high, using a fixed model: potential yield gain scales with the size of the gap (capped at 12 bu/ac), plus flat per-acre savings from variable-rate seeding, zone-based fertility, and overlap reduction. Crop prices are the latest USDA NASS national prices. Costs assume a $12,000 fixed setup plus $17/ac ongoing. It's a screening estimate, not a vendor quote.
How does this connect to crop prices and EQIP grants?
Yield tells you the size of the gap; Crop Prices tells you what closing it is worth in dollars using this month's or the marketing-year-average price; Grants & Funding tells you what USDA will reimburse toward the equipment or practices that close it. Each state page cross-links to the matching page in the other two hubs.
