  4. Sugar Beet • Sugar beet belongs to the Chenopodiaceae family. • It is a biennial plant with a 15–20% sucrose content at harvest. • It has a number of by-products which are important in agriculture.

  5. By-products of Sugar Beet • Sugar is extracted from the sugar beet plant and sold to consumers or used as a food additive. • Beet tops: Tops are cut from the plant during harvest and can be used to feed cattle and sheep.

  6. By- products continued • Beet pulp: Dried and shredded remains of the root which can be used as animal feed. • Molasses: A black syrup left over from sugar production which is used as an additive in animal feeds and is also used as an additive in silage production.

  7. Cultivation of Sugar Beet Soil suitability • Deep, well drained soils are needed for sugar beet production. • Compacted soils lead to forked roots. • Sugar beet also needs a pH of 6.5–7.0. Climate • Sugar beet is not frost resistant and best suited to a temperate climate. • Sunshine is also needed for sucrose production. • Sugar beet was traditionally grown in south-east Ireland.

  8. Cultivation of Sugar Beet Preparation of seedbed • Land should be ploughed and rotovated in spring for production of a fine seedbed. Time, rate and method of sowing • Sow in spring to avoid frost damage. This also allows for a long growing season. • Seed is sown at the rate of 100 000 /ha with a precision seeder.

  9. Fertilisers • Sugar beet fertilisers contain Boron (B) and Sodium (Na). • A lack of boron causes heart rot/crown rot in sugar beet. • Sodium is needed as sugar beet is descended from sea beet, a salt-loving plant.

  10. Weed Control and Rotation • Weed control • Weeds in the crop can be controlled by spraying a herbicide twice before full leaf cover. • Rotation • Beet should not be grown more than one year in three in a cereal-grassland rotation. • Rotation can be used to control the beet cyst nematode, the main pest of sugar beet.

  11. Diseases, Pests and Weed Control • Virus yellows • Transmitted by aphids • Causes chlorosis • Spray aphicides in spring and summer to reduce populations and control the spread of the viral disease • Rhizomania • Caused by Beet Necrotic Yellow Vein Virus (BNYVV) • Stunts root production • Increases root hair production • Prevents N uptake • Reduces sugar yield by 80% • Sow resistant seed varieties to slow spread of the virus

  12. Beet cyst nematode • Main pest of sugar beet • This worm causes stunted growth • Foliage turns yellow in colour • Plant wilts even with high moisture • Can be controlled using a nematicide

  13. Harvest, Yield and Storage • Sugar beet is harvested between September and December using a sugar beet harvester. • Tops are removed and left in the field, roots are transferred to a trailer. • Roots are stored in clamps, covered in straw to prevent frost damage. • Yield: • 40 t/ha roots • 25 t/ha tops • Beet tops are left in the field and must be wilted before feeding to cattle as they contain oxalic acid which causes scour. Wilting reduces the acid concentration.
