Forage Barley: Hay or Baleage, and When to Cut

By the XES Netting team — bale net-wrap manufacturer · Updated September 30, 2026 · ~10 min read

A thick stand of barley can look like the answer to a short hay supply. The difficult part is deciding what you are trying to save: this year's barley tonnage, a new perennial seeding underneath it, or a narrow opportunity to harvest before rain.

This guide is for US growers making barley forage for cattle. It brings together university guidance and questions from the AgTalk and HayTalk archives. XES manufactures net wrap, not seed or feed; we have not run a barley variety trial. Use local agronomic advice for the crop and a laboratory report with your veterinarian or nutritionist for feeding decisions.

Choose the forage barley variety before the harvest system

Barley forage is the harvested plant; barley straw is the residue after grain harvest. A quotation for one is not a quotation for the other. A second distinction matters just as much: the word “barley” does not tell you the variety's planting season, head traits or suitability for your market.

Utah State University Extension's November 2025 Small Grain Forage Production Guide, pages 2 and 11, identifies variety and harvest method as linked decisions. Its barley section allows spring or fall planting depending on variety, while warning that barley is less winter-hardy than some other small grains. Do not assume spring barley will behave like locally adapted winter wheat.

Before buying seed, establish:

• Growth habit and local adaptation: spring or winter type, a suitable planting window, and evidence from your region.
• Head characteristics: hooded, awnless, reduced-awn or rough-awned. Confirm the named variety rather than relying on a general “forage” label.
• Crop purpose: a stand grown mainly for barley forage, or a temporary companion over a perennial seeding.
• Buyer requirements: acceptable crop identity, package, forage analysis and intended livestock use.

Awns change the hay decision

Awns are the bristles on the seedhead. Utah State warns that awned small grains can cause mouth injury when grazed or fed as baled hay and advises harvesting those varieties before heading. Its discussion distinguishes ensiled forage from hay, but that is not a reason to declare any mature, sharp-awned bale suitable for any animal.

Montana State University's barley research describes hooded varieties developed for dry hay and differences among both feed and hay types. That irrigated trial covered 8 varieties over 3 years, 2000–2002. It supports checking actual traits; it is not a current nationwide variety ranking. Neither two-row versus six-row classification nor an old forum preference settles the whole purchase.

When to cut forage barley: boot or dough?

Boot means the developing head is still enclosed in the swollen upper leaf sheath. At heading, the head emerges. Later, kernels progress through milk and dough stages. These are crop observations, not calendar dates.

The broad trade-off is well established. University of Minnesota Extension reports that its spring-seeded small-grain research found the highest protein and digestibility at boot, when yield was only 38–42% of dough-stage yield. Those were fertilized, non-companion-crop trials in Minnesota. Do not use that percentage to forecast your field's yield or an undersown stand's response.

The question that changes the answer: what is growing underneath?

In a July 2025 AgTalk discussion, a grower asked whether boot-stage barley justified making silage rather than dry hay. A reply questioned cutting so early for the intended cattle. The grower then explained the constraint: dense barley was shading newly seeded sainfoin and perennial grasses.

That changes the objective. A recommendation aimed only at maximizing barley feed cannot resolve a decision about preserving the next several years of perennial production. Discuss the stand below the barley with a local agronomist, including shading, moisture competition and lodging. If your underseeding is alfalfa, our alfalfa establishment guide's companion-crop section covers that separate establishment decision.

Keep the two decisions in order: first identify the acceptable cutting window for the crop's purpose; then decide how to conserve the harvested barley. A need to remove a companion crop early does not automatically mean it must become baleage.

Barley hay or baleage: compare the complete job

Choose dry hay when you can cure the actual stem material to the appropriate moisture for your bale package and protect it afterward. Choose baleage when a shorter wilting period fits the crop and weather, and the entire wrapping, storage and feeding chain is ready. Wet bales without that chain are not a workable backup plan.

Penn State Extension's general baleage guidance gives 45–60% moisture as its optimal range. That is general baleage guidance, not a barley-specific experiment or permission to use any baler. Confirm the crop target with local Extension and the equipment requirements with the manuals. For the dry route, use our package-specific baling moisture guide rather than applying one moisture ceiling to every bale.

Net wrap holds a bale together; stretch film supplies the oxygen barrier for baleage. Net alone does not ferment or seal wet barley. Extra net also does not correct a poor wilt, damaged film or unsuitable equipment.

Do not use barley maturity or wrapping as a nitrate test

The most consequential question in the archive came from a grower whose early-boot barley baleage tested high in nitrates on fertile ground. The December 2025 follow-up explicitly says the forage had already had time to ferment. Waiting for fermentation was not a sufficient answer to that grower's problem.

North Dakota State University Extension lists barley among nitrate-accumulating crops. It explains that nitrogen supply and growth-limiting conditions matter, and that mature plants can still contain excessive nitrate. A different variety or later boot stage cannot clear an individual field.

Kansas State University's August 13, 2026 guidance adds two practical distinctions: nitrate concentration does not decline simply because forage is made into dry hay, and ensiled forage still needs testing before feeding. Its discussion of nitrate reduction during ensiling is not a guaranteed reduction for your barley bales.

• Before harvest: tell the receiving laboratory about the crop, stress and fertility history, intended cutting height and feeding method; follow its sampling instructions.
• Keep unlike areas separate: preserve the identity of stressed patches or differently managed fields rather than losing their records in one stack.
• Before feeding: obtain a representative analysis of the finished forage, including nitrate when indicated. Check whether the report uses nitrate or nitrate-nitrogen, and dry-matter or as-fed units.
• For the ration: have the veterinarian or nutritionist consider animal class, other feeds and water. Do not improvise a dilution ratio from a forum reply.

Our forage nitrate and prussic-acid guide explains why those hazards are different. A barley article does not need another unsourced threshold chart.

Compare feed, not water weight

A heavier barley baleage bale is not necessarily more feed than a lighter dry-hay bale. Start with actual weight and measured moisture. Dry-matter pounds = as-fed pounds × (1 − moisture fraction).

Consider these illustrative assumptions, not typical barley bale weights:

• A 1,000 lb dry-hay bale at 15% moisture contains 850 lb of dry matter: 1,000 × 0.85.
• A 1,500 lb baleage bale at 50% moisture contains 750 lb of dry matter: 1,500 × 0.50.

The heavier bale in this example contains less dry matter. That is an accounting comparison, not a judgment about which forage has better protein, digestibility or animal suitability. Add the actual forage test; our hay-test interpretation guide explains the report's different measures.

For a harvest budget, compare total seed, crop, harvest, transport, storage and feeding costs against usable tested dry matter. If comparing only the choice made after mowing, count the costs that actually change between hay and baleage. Label weather-loss assumptions rather than treating all dry hay as rain-damaged or all wrapped forage as loss-free.

Frequently asked questions

Is forage barley good hay for cattle?

Forage barley can supply useful cattle feed, but crop name alone does not establish its value or suitability. Variety, cutting stage, awns, conservation quality and nitrate concentration matter. Obtain a representative forage analysis and match it to the animals' requirements with a qualified nutritionist or veterinarian.

Should barley hay be cut at boot or soft dough?

Start with the objective. Earlier cutting generally favors protein and digestibility; later cutting can increase harvested dry matter. Rough awns and the needs of an undersown perennial can constrain waiting. Use local variety guidance and the intended conservation system rather than treating one stage as best for every field.

Can barley be planted in the fall for hay?

Some barley varieties are suited to fall planting and others are spring types. Utah State Extension cautions that barley is less winter-hardy than some other small grains. Confirm the named variety's growth habit, local adaptation and planting window instead of assuming any barley seed will overwinter like winter wheat.

Does making barley into baleage eliminate nitrate risk?

No. Fermentation can reduce nitrate under suitable conditions, but the reduction is not guaranteed to make the forage acceptable. The archive includes a grower reporting high nitrate after fermentation. Test the finished lot before feeding and have the report interpreted with the full ration, water and animal class.

Can net wrap alone preserve wet barley?

No. Net wrap binds the bale but is not an airtight preservation film. Barley intended for baleage needs appropriate moisture, suitable equipment, prompt stretch-film wrapping and an intact seal during storage. Wet barley held only by net is not equivalent to properly made baleage, regardless of the number of net layers.

Make the forage barley decision in the right order

Confirm the variety and the crop's purpose, choose an acceptable harvest window, and then select the conservation method you can complete. Keep nitrate testing and feed evaluation as separate decisions. That sequence is more useful than choosing “boot,” “dough” or “wrap it” before you know what the field must accomplish.

When round baling is the chosen route, select net wrap that fits your baler. It is one binding input in the system, not a substitute for curing, stretch film, testing or a feeding plan.
