How many bales of hay per acre can you yield? A guide to maximising output
Hay is a vital nutrient for livestock globally, particularly in dairy farming operations. When you're a hay farmer preparing for harvest, you're likely wondering about the projected yield. Thus, what factors should you take into consideration? And approximately how many bundles of hay per acre can you anticipate?

However, beyond these fundamental elements, what other factors should you take into account to optimize your hay production?
What is the average bales of hay yield expected per acre of land?
According to Graduate Farmer, in Kenya, hay farming can yield between 200 and 300 bales per acre per harvest. Nevertheless, these yields can differ depending on various factors including the type of grass, soil quality, and weather conditions.
In a worst-case scenario, where conditions are unfavorable, the hay yield per acre can drop significantly. Poor soil fertility, lack of adequate moisture, and suboptimal grass varieties can decrease productivity. In such cases, it is advisable to harvest around 100 to 150 bales per acre per cutting.
Are all hay bale sizes the same? No, they are not.

Hay bales are available in various sizes and differ based on a country or region. For instance, Smart Farmer Kenya indicates that the conventional two-string hay bale should have dimensions of 90 cm x 45 cm x 35 cm and a minimum weight of 15 kilograms, while 18-22 kilograms is considered optimal.
Internationally, the size of bales of hay varies. According to Measuring Know-How, the most common dimensions (average) for hay bales are:
- A general size dimension for this object is 46 × 89 × 36 centimetres or 18 × 35 × 14 inches, and it typically weighs around 23 kilograms or about 50 pounds.
- The object is measured at 5 feet in width and 6 feet in diameter, equating to approximately 1.5 by 1.8 meters, and it weighs approximately 1,500 pounds, which is around 680 kilograms.
What is the estimated amount of small square bales per acre?
In Kenya, the average yield for small square bales is approximately 200-275 bales, each weighing 15 kilograms, per acre of land for Boma Rhodes grass. Worldwide, the yield per acre ranges from 70 to 150 bales, each weighing 50 pounds or 22.6 kilograms, for Orchard grass.
What quantity of round bales can one acre yield?

Large-scale farming operations often favour round bales due to their size. Normally, you can anticipate realizing a yield of 2 to 4 round bales per acre on average. This estimate takes into account optimal growth conditions and a robust hay stand.
When using a standard 4x4 round baler, you may potentially achieve a greater yield, whereas larger 5x5 round bales may yield fewer bales per acre due to their size.
How many 5x5 round bales can be expected per acre?
A typical round hay bale, measuring 5x5 in size, generally weighs between 800-1,200 pounds depending on its density and moisture levels. In terms of yield, a bale of this size would produce around 1.5 to 2.5 bales per acre.
To achieve maximum output, be certain to cut at the right time and avoid drying the bales excessively, as too much moisture loss can reduce bale density.
What is the typical yield of hay per acre?
"Bales of hay" is another term often used for round bales. The expected yield depends on the bale size. For standard 4x5 foot bales, you might obtain 2 to 3 rolls per acre.
What is the expected output or production per unit area of land for hay?

There are three standard hay bale sizes. Large cylindrical rolls generate about five bales per acre, whereas large rectangular bales yield approximately 40 per acre. Small rectangular bales typically produce between 100 and 300 bales per acre.
How many bales of hay are typically found per acre in Kenya?
In Kenya, hay farmers can harvest between 200 and 300 bales of hay per acre, depending on the type of grass grown, the quality of the soil, and the farming methods used.
What is the average number of bales in one acre of land?
For Boma Rhodes grass (commonly found in Kenya), you can generally produce between 200 and 300 average bales of hay per acre, each weighing roughly 15 kilograms. In the US, Canada, Australia, Spain, and Italy, alfalfa hay (a type of legume plant) can yield up to 120 bales per acre, while orchard grass typically produces around 20 to 60 bales per acre.
How do you determine the number of bales per acre?
To calculate the number of bales per acre, you can use the following formula from Build Wise Calculator:
The number of bales equals field size in acres times yield per acre in tonnes times 1000, then divided by bale weight in kilograms.
Here's a step-by-step explanation:
- The entire land area from which you are gathering hay is included in this total.
- The total volume of hay generated per acre, measured in metric tons. One metric ton equals 1,000 kilograms.
- The weight of each bale is 15 kilograms in this case.
For example, if the area of your field is 1 acre, and you produce 2 tonnes (2000 kilograms) of crop per acre, the calculation would be:
Number of bales = 1 × 2 × 1000 / 15 ≈ 133 bales per acre
In this scenario, you would produce around 133 bales per acre, weighing approximately 15 kilograms each.
What are the financial prospects of hay farming in Kenya?

Livestock farming in Kenya can be lucrative with some farmers generating a substantial income. Variables that may impact hay profitability include investment costs, storage costs, and hay market prices.
In Kenya, what is the most commonly used type of grass for producing hay?
The most widely used grass for hay production in Kenya is Boma Rhodes grass, which boasts a high yield, excellent nutritional value, and good drought resistance. Another preferred option is Napier grass, commonly referred to as elephant grass, renowned for its rapid growth capabilities and ability to thrive in diverse soil and climatic conditions.
Alfalfa (Lucerne) is the most widely used legume plant for producing hay. Due to its high protein content and digestibility, alfalfa hay makes an ideal feed for dairy cattle, horses, and other livestock.
Final word
Now that you've calculated your hay yield per acre, you're ready for a successful harvest. It's crucial to harvest at the optimal time, maintain soil health, dry the harvested hay effectively, and ensure your equipment is in good working condition. Additionally, staying informed about the weather and preparing your fields properly will significantly impact your outcome.
