Beetroot Planting
Vegetable Farming in South Africa
Beetroot seedlings grown in a container.
Propagation
Propagation is from seed.
Planting Method
Plant beetroot seeds directly into plant area 20 mm deep. Seeds are planted in rows that are 20 cm apart and at first 2 cm apart and once established are thinned out and these plants can be used to fill gaps.
Seeds can also be planted into seedling trays and once seedlings are established and grown about 10 cm can be planted out. This tends to not be adopted by big commercial growers as a good production requires about 500 000 plants per hectare and this process is costly.
Spacing
Plants should finally be spaced 5 to 10 cm apart depending on the size of beet desired. They are planted in rows that are 20 cm apart. With paths left for implement wheels and for labour you should be left with about 600 000 to 800 000 plants per hectare. Again this varies from producer to producer depending on what usage the crop is destined for.
Sowing Time
Beetroot can be planted throughout the year in mild temperate climates. But the best resultant crops in South Africa are planted from August to December.
Growth Period
Two months (Eight weeks) for smaller beets of 40 to 50 mm diameter and 3 months (12 weeks) for bigger beets of 60 to 70 mm in diameter. If left too long in the ground they can start to harden and quality for fresh sales is diminished.
Fertilization
Before planting and during the preparation of the raised planting beds compost and an allocation of chicken manure can be worked into the top 200 mm of soil. After planting, an organic mulch can be applied over the planted area.
Once the plants have established themselves at about three weeks after emergence apply 400 kg of LAN or equivalent liquid fertilizer. Three weeks after the first application apply the same level of Nitrogen as the first application in the form of a Potassium Nitrate.
Irrigation
Drip irrigation can be used on Beetroot seedlings.
Irrigate lightly after planting to ensure the soil area is properly moistened. Do not over irrigate as this will effect germination. About 25 mm during the first ten days should suffice. Once the plants emerge between 35 and 50 mm per week will be the level of irrigation. The higher applications of as much as 50 mm per week are needed if the temperatures and evaporation levels are high.
