Beetroot Crop Management
Vegetable Farming in South Africa
Crop Rotation
Crop rotation should always be practiced in vegetable production to combat pests and diseases.
Yield (tonnes per hectare)
Conservative: 15 tonnes
Average: 25 tonnes
Good: 35 tonnes
Preserved beetroot in recyclable containers.
Harvesting
Harvesting is done when the average beetroot reaches about 7 centimetres in diameter. Earlier harvesting does take place if the market requests a smaller beet.
Harvesting can be done by hand, but most large commercial operations harvest mechanically.
Storage
Beetroot should be cooled to between four and five degrees centigrade and a relative humidity of over 90 percent within as short a time after harvest as possible, normally within 6 hours of harvest.
But when climate temperatures are higher, then the cooling must take place quicker. the beetroot can be stored for up to six months at one to two degrees centigrade at a relative humidity of 90+ percent.
Pests
Red Spider, Aphids, Cut worm and Nematodes.
Diseases
Some common diseases are Cercospora Leaf Spot, Scab, Brown rust, Downey Mildew and Root rot.
