Nevada grows far more than most people expect from the driest state in the country. Alfalfa hay dominates the landscape, but farmers across the state also produce onions, potatoes, garlic, barley, wheat, and a growing range of specialty and forage crops. Nearly all of it depends on irrigation, which makes water availability the single biggest factor shaping what gets planted and where. The story of Nevada’s crops is really a story about creative farming in a place where rain alone cannot sustain a harvest.
Alfalfa and Hay Run the Show
If you fly over the green circles dotting northern Nevada’s valleys, you’re almost certainly looking at alfalfa. It is by far the state’s most valuable crop and the backbone of Nevada agriculture. Alfalfa hay feeds cattle and dairy operations both inside the state and across the West, and Nevada ships large quantities of it to markets in California and beyond. The crop thrives in Nevada’s high-desert climate because it tolerates alkaline soils, benefits from the intense sunshine, and produces multiple cuttings per season when irrigated. Most alfalfa fields rely on center-pivot or flood irrigation fed by a mix of surface water diversions and groundwater wells.
Other types of hay, including timothy and grass hay blends, also contribute to the state’s agricultural output, though on a smaller scale than alfalfa. Timothy hay, in particular, has found a steady niche market supplying feed for horses and small animals. Together, hay crops account for the vast majority of Nevada’s cultivated acreage.
Onions, Potatoes, and Garlic
Nevada’s volcanic and alluvial soils, combined with wide temperature swings between day and night, produce root vegetables and alliums with a reputation for strong flavor. Onions are one of the state’s signature crops, grown primarily in the Fallon area and parts of northern Nevada. The region’s dry air reduces the risk of fungal diseases that plague onion growers in more humid climates, and the sandy loam soils drain well enough to discourage bulb rot.
Potatoes have a long history in Nevada, particularly in the Elko and Humboldt County areas, where cooler temperatures at elevation suit the crop’s growing requirements. Nevada potatoes tend to be sold for processing or fresh markets within the region. Garlic rounds out the allium picture, grown in small but dedicated operations that capitalize on the same dry, sunny conditions that benefit onions. These crops all share a common need for reliable irrigation water, which becomes more difficult to secure as competition for water intensifies across the state.
Cereal Grains and Field Crops
Barley and wheat are both grown in Nevada, though on far less acreage than hay. Barley has historically been the more common of the two, partly because it matures quickly enough to fit within Nevada’s short growing season at higher elevations. Some Nevada barley goes to livestock feed, while a portion enters the malting market. Winter wheat appears in valleys with enough irrigation capacity to carry the crop through, but grain farming in Nevada faces stiff economic headwinds: yields per acre tend to be lower than in the major grain-producing states of the Midwest, and the cost of irrigating a grain crop in the desert eats into already thin margins.
Corn, while not a major Nevada crop, does appear in small acreages, primarily as silage for dairy and beef operations rather than as grain corn. The hot summers in some Nevada valleys provide enough heat units for silage corn, but the water demands are significant. As a result, corn tends to show up only where farms have secure water rights and enough acreage to justify the investment.
Forage Sorghum as a Water-Saving Alternative
One of the more promising developments in Nevada agriculture is the exploration of forage crops that use less water than alfalfa. Sorghum-sudangrass hybrids have attracted attention because they are drought-tolerant warm-season grasses that can produce a substantial tonnage of livestock feed on less irrigation. A varietal evaluation trial conducted in Fallon, Nevada, tested multiple sorghum-sudangrass cultivars during an unexpectedly shortened irrigation season. Even with reduced water, the trial produced biomass yields averaging about four tons per acre across all varieties, with a range from roughly 2.7 to 5.4 tons per acre depending on the cultivar.1University of Nevada, Reno Extension. Forage Sorghum-Sudangrass Varietal Evaluation During a Short Irrigation Season in Fallon, Nevada
Those numbers are notable because the yields were comparable to sorghum-sudangrass grown under rainfed conditions in Texas, a state with substantially more rainfall. The differences among varieties appeared to come down to varying tolerance for water deficit rather than simply plant height or vigor. For Nevada ranchers looking to stretch limited water supplies, sorghum-sudangrass offers a legitimate fallback when irrigation allocations get cut. It won’t fully replace alfalfa, which commands a higher price per ton and has well-established markets, but it gives producers a way to keep growing feed in dry years rather than leaving fields idle.
Specialty and Niche Crops
Small-scale and specialty agriculture has been growing in Nevada, particularly near population centers like Reno and Las Vegas. You’ll find farms producing:
- Herbs and greens: Basil, lettuce, microgreens, and other leafy crops grown in greenhouses or under shade structures, often for local restaurant supply.
- Melons and peppers: The extreme summer heat in southern Nevada, which most crops cannot tolerate, actually works well for melons, chili peppers, and other heat-loving produce when irrigation is available.
- Grapes and wine: A small but real wine grape industry exists in parts of northern Nevada, where elevations and diurnal temperature swings can produce grapes with concentrated sugars and acidity.
- Lavender and other aromatics: Several farms in the Reno-Tahoe region grow lavender for essential oils, dried flower products, and agritourism.
These niche operations rarely show up in statewide agricultural statistics because their total acreage is tiny compared to hay and livestock. But they matter for local food systems and are often the farms most visible to the public through farmers’ markets and farm-to-table supply chains.
Why Water Determines Everything
Nevada receives an average of roughly nine inches of precipitation per year across the state, making virtually all crop production dependent on irrigation. The water comes from two main sources: surface water diverted from rivers and streams, much of it originating as mountain snowmelt, and groundwater pumped from underground aquifers. Many agricultural valleys use both sources together, switching to groundwater when surface flows decline in summer or during drought years.
This dual-source system is under increasing strain. An integrated modeling study of an irrigated river valley in the northwestern Nevada and northern California border region found that as climate change reduces snowpack, farmers will need to lean more heavily on supplemental groundwater to offset reduced surface water deliveries. But even with that shift, total crop water consumption, which serves as a proxy for crop yield, is projected to decline. The problem is that the timing and distribution of water supply changes hit some growers harder than others, depending on where they sit in the irrigation system and what water rights they hold.2Water Resources Research. Integrated Hydrology and Operations Modeling to Evaluate Climate Change Impacts in an Agricultural Valley Irrigated With Snowmelt Runoff
In practical terms, this means that the mix of crops grown in Nevada is likely to keep shifting toward less water-intensive options. Alfalfa, for all its economic importance, is a thirsty crop. Pressure to fallow alfalfa fields or convert them to lower-water alternatives like sorghum-sudangrass, native grasses, or dryland pasture will grow as aquifers decline and snowmelt becomes less predictable.
The Role of Native Plants and Restoration Seeding
Not all planting in Nevada is about producing crops for market. A significant amount of effort goes into restoring native vegetation on former farmland, particularly in areas where irrigation has been curtailed and bare soil creates dust pollution problems. When fields are abandoned without revegetation, the loose, dry soil generates fugitive dust that degrades air quality across wide areas.
Research in Nevada has shown that a combination of furrowing fields across the prevailing wind direction and direct-seeding native perennial shrubs and grasses can cut dust emissions by more than 95%. Among the species tested, Indian ricegrass performed best in deep sandy soils, while fourwing saltbush established most consistently across a range of conditions. Living plant cover from seeded species varied between roughly 35% and 97% from year to year, tracking closely with how much rainfall the site received.3Journal of Environmental Quality. Seeding Native Plants to Restore Desert Farmland and Mitigate Fugitive Dust and PM10
This kind of work sits at the intersection of agriculture and land management. Some of these native seed species are themselves commercially produced on Nevada farms, creating a small but meaningful market for native plant seed. As more marginal cropland comes out of irrigation, the demand for restoration seed is only going to increase, and the farms that grow it occupy an unusual niche: they’re farming the plants that replace farming.
Livestock and the Crops That Support Them
It’s impossible to talk about Nevada’s crop picture without mentioning livestock, because cattle ranching is the largest single sector of the state’s agriculture, and most of the crops grown in Nevada exist to feed animals. The vast majority of alfalfa, other hays, silage corn, and grain barley produced in the state goes directly into cattle feed, either on the same ranch or sold to feedlots and dairies in neighboring states.
Nevada’s rangelands are enormous but sparse, meaning cattle rely on irrigated hay and supplements to get through winter months and drought periods when open range can’t sustain them. A bad hay year, whether caused by water curtailments, frost, or pest pressure, ripples immediately through the livestock economy. Ranchers sometimes respond by reducing herd size, buying hay from out of state at premium prices, or switching to cheaper forage options. This tight coupling between crop production and livestock operations is one reason why experiments with alternative forages like sorghum-sudangrass carry real economic significance for the state.
How Geography Splits the State
Nevada’s agricultural geography breaks into a few distinct zones, each with its own character. The northern valleys, places like the Lahontan Valley around Fallon, the Lovelock area, and valleys in Elko and Humboldt counties, account for the bulk of the state’s crop production. These areas benefit from rivers fed by Sierra Nevada and Ruby Mountain snowmelt, plus relatively cooler summers that keep evapotranspiration somewhat in check. Alfalfa, onions, potatoes, and small grains concentrate here.
The southern part of the state, dominated by the Mojave Desert and the Las Vegas metro area, has very little traditional field crop agriculture. Summer temperatures regularly exceed 110°F, and surface water is essentially limited to Colorado River allocations, which face their own well-publicized shortages. What farming does exist in the south tends to be small-scale produce, date palms, and greenhouse operations. Clark County’s agricultural footprint is a fraction of what exists in the north.
The central part of the state is a patchwork. Valleys like Diamond Valley, Smith Valley, and Mason Valley support irrigated agriculture where groundwater or river water is available, but many of these basins face over-appropriation, meaning more water has been legally allocated than the aquifer or river can sustainably provide. Diamond Valley, for instance, has been at the center of discussions about groundwater management reform precisely because decades of pumping for agriculture have drawn the water table down to levels that threaten long-term viability.
What the Future Looks Like
Nevada’s agricultural sector is small in absolute terms compared to neighboring California or Idaho, but it punches above its weight in the state’s rural economy, where ranching and farming are the primary employers and land uses outside of mining. The trends shaping the next few decades are fairly clear: less snowmelt, more competition for groundwater, growing urban demand for water from Las Vegas and Reno, and continued pressure to do more with less.
That pressure is already changing what gets planted. Trials of drought-tolerant forages, investments in more efficient irrigation technology, and the gradual retirement of the most marginal cropland are all underway. Some growers are exploring controlled-environment agriculture, growing leafy greens and herbs in hydroponic or aquaponic systems that use a fraction of the water required by open-field farming. These operations are tiny today but align well with a state where water is the binding constraint on everything.
The crops Nevada grows in twenty years will almost certainly still include alfalfa, onions, and potatoes. But the acreage devoted to each, and the share of water they receive, will depend on how the state navigates a set of hard trade-offs between agricultural tradition, urban growth, and a warming climate that is making the desert even drier. For now, if you drive through the green valleys of northern Nevada in summer, the fields of alfalfa and onions look remarkably lush for a state that averages less than ten inches of rain. That contrast tells you everything about how much ingenuity and infrastructure goes into growing food here.
