Beet harvesting: expert advice on timing and techniques

Beet (Beta vulgaris) is a crop of interest to several professional supply chains: from the fresh produce market to food processing, as well as the commercialisation of younger leaves.

For farms, achieving a uniform, high-quality crop depends not only on agronomic field management, but also on the ability to identify the right time for harvesting and to use equipment suited to the product’s intended market.

Beet harvesting involves different operations depending on the product. When the main product is the root, it must be lifted from the soil while minimising breakage, abrasions and losses. When the leaves are also marketed, however, cutting must be precise and gentle, especially for markets that require a fresh, uniform product ready for subsequent processing stages.

In this article, we analyse crop development, harvesting techniques and post-harvest best practices, with a focus on Ortomec solutions designed for the professional management of leafy vegetables. 

Beet development before harvesting

To plan harvesting correctly, it is important to monitor plant development throughout the entire crop cycle. Beet initially goes through a phase of emergence and leaf growth, followed by the progressive enlargement of the root.

During the first few weeks, the crop directs its resources towards developing the leaf canopy and root system. Uniform growth at this stage is essential for achieving an even field and making subsequent mechanised operations easier.

As the crop cycle progresses, the root gradually increases in diameter and weight. The rate of development depends on several factors:

• cultivated variety;
• planting density;
• water availability;
• soil structure and fertility;
• weather conditions;
• intended market for the crop.

For farms, it is important to assess maturity at several points across the field. A field that appears uniform may in fact show significant differences between different areas, affecting product sizing and commercial yield.

Before harvesting, it is therefore advisable to carry out regular sampling, checking:

• average root diameter;
• crop uniformity;
• surface integrity;
• flesh firmness;
• health of the leaves;
• presence of cracks, deformities or damage.

These checks make it possible to schedule machine operations more accurately and coordinate harvested volumes with the farm’s sorting, packaging or processing capacity.

How to harvest beet

The harvesting technique varies depending on the part of the plant intended for commercialisation.

When harvesting the root, the soil is generally loosened using lifting or extraction systems. The machine must work at the correct depth, separating the root from the soil without causing excessive cuts, impacts or abrasions.

A professional harvesting process may include the following stages:

1. removal or management of the leafy part;
2. loosening the soil around the roots;
3. lifting and extraction;
4. removal of excess soil;
5. conveying and collection;
6. preliminary product sorting.

Equipment settings must take soil texture and moisture into account. Soil that is too wet can increase the amount of soil adhering to the roots and encourage compaction, while excessively dry and hard soil can increase the risk of abrasions or breakage.

Forward speed must also be adapted to field conditions. The aim is not simply to increase hourly capacity, but to maintain a steady flow that reduces mechanical stress and preserves the product’s commercial value.

Can beet remain in the ground for too long?

Leaving beet in the ground beyond the optimum harvesting time can lead to several problems. Roots may become excessively large, lose uniformity or develop a texture that is less suitable for their intended commercial use.

Remaining in the soil for too long can also increase exposure to:

• temperature fluctuations;
• waterlogging;
• pathogen attacks;
• pest damage;
• cracks or deformities;
• loss of uniformity among roots.

Harvesting should therefore not be determined solely according to the calendar. The size required by the customer, weather conditions and the actual state of the field must also be considered.

For farms working with supply contracts or industrial processing schedules, delaying harvesting excessively can result in batches that fall outside the required size range, increase waste and complicate subsequent processing operations.

When to harvest beet

The ideal time depends on the variety, crop cycle and intended use of the product. Beet intended for the fresh market is generally harvested once it has reached the required commercial size and has an intact surface, regular shape and suitable firmness.

The assessment should take into account:

• average root diameter and weight;
• crop uniformity;
• colour and firmness;
• market or industrial customer requirements;
• forecast weather conditions;
• daily harvesting and processing capacity.

It is preferable to harvest when the soil is dry enough to allow machinery to operate, but not so compact that extraction becomes difficult.

Planning must also be coordinated with subsequent stages. Harvesting volumes that exceed cooling, sorting or packaging capacity can lead to product build-up and increase the risk of deterioration.

Harvesting beet leaves

Beet leaves can represent a commercial product in their own right, especially when harvested young and intended for the fresh market, fresh-cut produce or baby leaf mixes.
In this case, harvesting is very different from root extraction. The leaves must be cut evenly, avoiding fraying, crushing and contamination with soil.

The main factors to control are:

• cutting height;
• crop uniformity;
• integrity of the leaf blade;
• presence of yellowed or damaged leaves;
• gentle conveying;
• rapid transfer to the post-harvest line.

When the aim is to allow the plant to regrow, cutting must not damage the heart of the plant. An incorrect cutting height can damage the growing point and reduce the plant’s ability to regrow.
For this type of product, Ortomec harvesters for leafy vegetables are designed to provide precise, gentle and adjustable cutting. Height control systems allow the machines to follow the ground profile and preserve the plant, while the conveying system helps limit mechanical damage to the leaves.

For farms marketing beet leaves, mechanisation offers significant advantages:

• greater working capacity;
• reduced labour requirements;
• more consistent cutting height;
• more uniform batches;
• less product handling;
• improved organisation of field operations.

Ortomec solutions are developed to combine precision, gentle handling and productivity when harvesting leafy crops, while also helping to improve working conditions and the hygienic quality of the product.

Post-harvest management of beet

Beet quality can decline rapidly if the product is not handled correctly after lifting or cutting. Post-harvest operations should therefore be planned before machinery enters the field. 

Root management

After harvesting, the roots should undergo an initial sorting process to remove:

• broken or damaged produce;
• deformed roots;
• specimens outside the required size range;
• produce showing signs of rot;
• plant residues and excess soil.

Washing, grading and packaging depend on the intended market. In all cases, impacts and drops should be minimised, as surface damage can accelerate deterioration and reduce shelf life.

When the product is not processed immediately, it should be transferred to suitable environments, maintaining temperature and humidity conditions compatible with the planned storage period.

Leaf management

Leaves require even faster handling. After cutting, they should be:

• protected from direct sunlight;
• collected in clean, ventilated containers;
• transferred rapidly to cooling;
• sorted to remove damaged or non-compliant parts;
• maintained throughout an uninterrupted cold chain.

The time between the field and cooling directly affects turgidity, colour and commercial shelf life. For this reason, harvester capacity and the organisation of the processing facility must be correctly matched.

Using machines that provide uniform cutting and gentle conveying helps reduce subsequent sorting work and preserve a higher percentage of marketable product.

Conclusion

Beet harvesting is a process that must be planned according to the final product. Root extraction requires equipment capable of working the soil and lifting the product while minimising breakage and abrasions; leaf harvesting, on the other hand, requires cutting precision, gentle handling and rapid post-harvest management.

For a farm, efficiency does not depend solely on machine speed. It is the result of coordination between:

• field uniformity;
• correct identification of maturity;
• equipment adjustment;
• daily processing capacity;
• logistics management;
• quality standards required by the customer.
