When to Cut Triticale for Hay: Maximizing Forage Quality and Yield
The optimal time to cut triticale for hay is at the late boot stage to early heading stage, balancing yield and quality. This timing ensures the highest digestible energy and protein content while minimizing fiber.
Understanding Triticale for Hay Production
Triticale, a hybrid of wheat (Triticum) and rye (Secale), has emerged as a valuable forage crop, offering a unique combination of desirable traits from both parent plants. It boasts high yield potential, cold tolerance, and disease resistance, making it a versatile option for livestock producers seeking high-quality hay. Understanding its growth stages and nutritional value is crucial for optimal hay production.
Benefits of Triticale Hay
Triticale hay provides numerous advantages for livestock operations:
- High Yields: Triticale generally produces higher dry matter yields compared to other small grain forages like oats or barley.
- Nutritional Value: When harvested at the correct stage, triticale offers a good balance of energy and protein, suitable for various livestock needs.
- Flexibility: It can be planted in the fall or spring, providing flexibility in cropping systems.
- Soil Health: As a cover crop, triticale can improve soil health by suppressing weeds, reducing erosion, and increasing organic matter.
- Adaptability: Triticale is adaptable to a wide range of soil types and climates.
Key Growth Stages and Harvest Timing
Determining the optimal harvest timing is paramount for maximizing forage quality. Here’s a breakdown of key growth stages and their relevance to hay production:
- Vegetative Stage: Rapid growth of leaves and stems. Nutrient concentration is high, but yield is low.
- Boot Stage: The developing seed head is enclosed within the boot (the sheath of the flag leaf). This is the early point for considering harvest.
- Late Boot Stage: The boot is swelling, and the seed head is almost ready to emerge. Ideal harvest timing starts here.
- Heading Stage: The seed head has fully emerged from the boot. Quality starts to decline more rapidly at this point.
- Milk Stage: Kernels are developing and contain a milky fluid. Fiber content increases significantly.
- Dough Stage: Kernels become doughy. Forage quality declines further.
- Mature Stage: Kernels are fully developed and hardened. Quality is at its lowest.
The window of opportunity for harvesting high-quality triticale hay is relatively narrow. Delaying harvest beyond the early heading stage leads to a rapid decline in digestibility and protein content.
Factors Influencing Harvest Timing
Several factors can influence the ideal harvest time:
- Variety: Different triticale varieties may mature at different rates. Consult variety-specific recommendations if available.
- Climate: Warm, dry conditions can accelerate maturity, while cool, wet conditions can delay it.
- Soil Fertility: High nitrogen fertility can promote vegetative growth and potentially delay heading.
- Livestock Needs: The intended use of the hay (e.g., for lactating dairy cows vs. beef cattle) may influence the desired forage quality.
The Harvesting Process
Harvesting triticale for hay involves several key steps:
- Cutting: Use a sickle bar mower or disc mower to cut the triticale.
- Conditioning: Use a mower-conditioner to crimp or crush the stems, promoting faster drying.
- Tedding (Optional): Tedding involves spreading the hay to increase surface area and speed up drying, especially in humid conditions.
- Raking: Rake the hay into windrows when it is partially dry.
- Baling: Bale the hay when it reaches the desired moisture content (typically 15-20% for small square bales and 12-18% for large round bales).
- Storage: Store bales in a dry, well-ventilated area to prevent spoilage.
Common Mistakes to Avoid
- Delaying Harvest: This is the most common mistake. Harvesting too late results in lower-quality hay.
- Baling Too Wet: Baling hay with excessive moisture can lead to mold growth, spoilage, and even spontaneous combustion.
- Insufficient Conditioning: Properly conditioning the hay is essential for fast and even drying.
- Improper Storage: Storing hay in a damp or poorly ventilated area can lead to significant losses.
- Ignoring Weather Forecasts: Harvesting hay requires favorable weather conditions. Closely monitor weather forecasts to avoid rain damage.
Monitoring Moisture Content
Accurate moisture measurement is essential for preventing spoilage. Several methods can be used:
- Electronic Moisture Testers: These devices provide a quick and convenient way to measure moisture content.
- Oven Drying: A more accurate but time-consuming method involves drying a sample in an oven and calculating the moisture loss.
- The “Twist Test”: While less precise, experienced hay producers can often estimate moisture content by twisting a handful of hay.

Frequently Asked Questions (FAQs)
What happens if I cut triticale for hay too early?
Cutting too early, before the boot stage, results in lower yields and potentially higher moisture content, making drying more difficult. The nutritional value may not be significantly higher to compensate for the yield loss. You’ll have less tonnage of a slightly more nutritious product.
How can I tell if my triticale is at the boot stage?
Carefully examine the flag leaf sheath (the boot). If you can feel the developing seed head inside, and the boot is starting to swell noticeably, your triticale is at the boot stage. Begin to regularly check your fields as this stage approaches.
What is the ideal moisture content for baling triticale hay?
The ideal moisture content for baling triticale hay is typically 15-20% for small square bales and 12-18% for large round bales. Consistent monitoring with a moisture tester is highly recommended.
Does the type of livestock I’m feeding influence the ideal harvest time?
Yes. For lactating dairy cows or young, growing animals, earlier harvest (late boot stage) is preferable to maximize protein and digestibility. For mature beef cattle, a slightly later harvest (early heading) may be acceptable, as they can tolerate higher fiber content. Always consider the specific needs of your livestock.
How does conditioning affect drying time?
Conditioning, by crimping or crushing the stems, creates more surface area for moisture to escape, significantly reducing drying time. This is especially important in humid climates.
What are the risks of baling hay that is too wet?
Baling hay that is too wet creates an environment conducive to mold growth and bacterial activity, leading to spoilage, nutrient loss, and the potential for spontaneous combustion. Safety is paramount; never risk baling overly moist hay.
How can I prevent my triticale hay from molding during storage?
Ensure that the hay is properly dried before baling, store bales in a dry, well-ventilated area, and consider using hay preservatives if necessary. Proper ventilation is key to preventing moisture buildup.
Can I use triticale silage instead of hay?
Yes, triticale can be ensiled. The optimal stage for ensiling is typically the dough stage. Ensiling preserves nutrients and can be a valuable option in regions with frequent rainfall.
How many cuttings can I get from a triticale crop?
Typically, triticale is a single-cut forage. Regrowth is generally slow and not sufficient for a second harvest of hay.
What kind of fertilizer should I use for triticale grown for hay?
A balanced fertilizer program that includes nitrogen, phosphorus, and potassium is essential for maximizing yield and quality. Soil testing is recommended to determine specific nutrient needs. Base your fertilizer plan on accurate soil analysis.
Can I graze triticale after cutting it for hay?
While possible, grazing after cutting for hay is generally not recommended as it can hinder regrowth. Prioritize either hay production or grazing. Consider managing triticale specifically for grazing as a separate strategy.
What are the key indicators of high-quality triticale hay?
High-quality triticale hay should have a bright green color, a pleasant aroma, a soft texture, and minimal stemminess. Lab analysis can provide more precise information on nutrient content and digestibility. Visual inspection is a good start, but laboratory testing provides definitive data.
