Top Crops in Kansas: What USDA Data Shows

Field crops cover 14.1M acres in Kansas, a meaningful share of the state's working land that anchors rural employment and downstream grain handling, livestock feeding, and processing infrastructure.

Corn leads the mix at roughly 39% of Kansas's tracked production, with the rest spread across 7 other major field crops. That balance is closer to a diversified row-crop state than a monoculture.

Corn is the backbone of U.S. row-crop agriculture, used for livestock feed, ethanol, sweeteners, and exports. Iowa, Illinois, and Nebraska anchor the Corn Belt, and weather across these states moves global feed and ethanol markets.

Kansas ranks #8 of 35 tracked states for total field-crop production, supplying roughly 5.3% of combined output. That places it in the upper-middle tier of U.S. crop-producing states.

Kansas shares its lead crop (Corn) with 3 other tracked states: Iowa, Illinois, Nebraska. Together these states form the core of U.S. corn production and tend to move in concert with weather, planting decisions, and price cycles.

National-level rankings, harvested acres, and yield-per-acre data for every U.S. crop are published by the USDA National Agricultural Statistics Service. Export demand for the same crops — a major driver of farmgate prices in Kansas — is tracked by the USDA Foreign Agricultural Service.

U.S. row-crop acreage shifts every spring with relative crop prices, input costs (fertilizer, diesel, seed), and the previous year's weather. Corn acreage in Kansas responds to the corn-soybean-wheat price ratio published each winter; a higher corn price relative to alternatives pulls more acres into corn the following season. Yields, in turn, are dominated by growing-season weather — June rainfall, July temperatures, and timely first-frost dates set the gap between a record harvest and a USDA disaster declaration.

Over the last decade, U.S. crop production has trended upward on yield improvements (genetics, precision agriculture, better nitrogen management) even as harvested acres have stayed roughly flat. Kansas's long-run trajectory follows that same arc: production records are typically set in years that combine modern hybrids with favorable weather, while disappointing years usually trace back to drought, late planting, or early frost rather than reduced acreage.

For Kansas farmers, this mix means revenue is meaningful but balanced — a bad corn year hits the bottom line, but secondary crops cushion the blow. For grain buyers, processors, and shippers, Kansas's output is a first-call sourcing region for corn and wheat. For policymakers, federal support programs (Title I commodity payments, crop insurance, ARC/PLC) flow disproportionately into states with 8-crop profiles like this one.

Crop insurance premium subsidies, marketing-loan rates, and ARC/PLC payment triggers are all calibrated against USDA NASS production data — the same dataset behind this page. That makes the official numbers more than a statistical curiosity: they directly determine federal farm-program payouts to Kansas producers in years when prices or yields fall below benchmarks.
