Introduction
Sugar beet is a major industrial crop, grown for the extraction of the sugar contained in its root. It plays a vital economic role in many temperate agricultural regions and is an important source of natural sugar.
Benefits
- Very rich in sucrose (up to 18%).
- Good profitability per hectare.
- Relative drought resistance thanks to its taproot.
- Valorisation of by-products (pulp, leaves, green manure).
Main varieties
- Eloise : good yield, good wealth.
- Orbis : Strong disease tolerance.
- Isabella : suitable for heavy and wet soils.
Ideal growing conditions
Soil: deep, loose, rich in organic matter, well drained.
Climate: humid temperate with moderate temperatures.
Exposure: full sun.
Rotation: avoid short rotations to limit soil diseases.
Crop Cycle
Sowing: March to April.
Flowering: not sought after (biennial plant).
Harvest: September to November.
Maintenance techniques
Fine, clod-free soil preparation for good sowing.
Fractional nitrogen application according to the stage of growth.
Mechanical and chemical weeding.
Foliar and root disease surveillance.
Common issues
- Diseases: cercosporiosis, rhizomania, viral jaundice.
- Pests: flea beetles, aphids, soil nematodes.
Recommended Products
- Specific fungicides against cercosporiosis.
- Natural or selective insecticides against aphids.
- Balanced nitrogen fertilisers + trace elements (boron, manganese).
Anecdote
Sugar beet was introduced to Europe in the nineteenth century as an alternative to sugar cane. Napoleon I strongly encouraged its cultivation to limit the importation of sugar. Today, it is a major source of sugar in Europe.
FAQ
Sugar beet is grown to produce sugar, while fodder is used as feed for livestock.
Between March and April, on well-prepared, warmed and sufficiently moist soil.
By controlling irrigation, avoiding water stress and balancing nitrogen inputs.
