A visit to the operational nerve centre of Heystek Farming, situated in the Pongola area of northern KwaZulu-Natal, reveals a highly organised and diversified farming operation that is clearly the pride of brothers Riaan and WJ Heystek. There are fields of irrigated sugar cane and green peppers, citrus orchards, banana plantations and cucumber tunnels.

Their father, Willie, established Heystek Farming, but today focuses on managing the farm’s finances, while Riaan and WJ run the operation. In addition, the pair manage a separate entity, Heystek Farm Produce (HFP), which they established in 2013 to farm mainly jam tomatoes.
Bananas, which the brothers first planted in December 2019, are HFP’s latest enterprise.
“We chose bananas because we know they grow well in Zululand’s subtropical climate,” explains Riaan. “They’re also very popular among fresh-produce hawkers. For years, we’ve been supplying our other fresh produce to local informal traders. We have a good business relationship with them, and they told us they’d be willing to buy our bananas.”
Riaan and WJ ploughed out the sugar cane fields closest to HFP’s ripening rooms and packhouse so that future banana harvests would not have to be transported far to these facilities. Bananas bruise easily, so the less they are handled, the less risk of the consumer ending up with unappealing fruit.
In addition, the soil of the ploughed-out sugar cane fields has a relatively high clay content (between 25% and 40%), a beneficial soil organic carbon content of 2% to 3%, and high water-holding capacity. Banana plants do well in such soil conditions.
MAKING A GOOD BED FOR BANANAS
“After harvesting the sugar cane, we let the field stand for approximately four weeks,” says WJ. “During this time, we irrigated it lightly to enable the sugar cane leaves to regrow so that we could apply glyphosate herbicide to the young plants.
“The glyphosate, which is systemic, kills whole sugar cane plants as well as any weeds growing in the fallow field before bananas are planted.”
The dying plants were then disced into the soil using a disc harrow. The decomposing plants helped improve soil structure and provide organic nutrients for the banana plants. Discing was followed by a subsoiler to loosen any compaction down to a depth of 600mm to improve aeration and moisture dispersion within the soil, and to enable the roots of the banana plants to grow unimpeded.
The soil was then disced again, and this was followed by a power harrow that created a fine soil tilth. The tilth was necessary for the important root-to-soil contact needed by the banana seedlings once they were transplanted into the field.

Growing sweet potatoes
The sweet potato is a warm-season crop and does not fare well in cool temperatures. Implementing a crop rotation strategy is also essential to keep pests and diseases at bay.
The evolution of power in SA's agri machinery market
It is unlikely that South Africa’s commercial agriculture sector would have achieved its internationally respected status were it not for the investment that farmers have made in mechanisation. Lloyd Phillips spoke to a number of experts about some of the main agricultural machinery sales trends.
Putting crop rotation into perspective
When developing a crop rotation programme, one must take into consideration the various pests and diseases that may infect different crops in order to avoid disastrous results, says Bill Kerr.
The changing environment
The Internet of Things, where machinery and devices (often fitted with sensors) share data online, has enabled tractors and other agricultural machinery to become far more efficient and easier to operate. This, combined with mechanical innovations, is helping farmers produce more with less. Glenneis Kriel reports.
Giving farmers the advantage!
New machinery is indispensable as a support for agricultural activities during difficult times such as COVID-19, says Jaco du Preez, product specialist at CNH Industrial, distributor of New Holland in South Africa.
Breeding for efficiency adds value for this cattle farmer
Anneri Otto, who farms near Coligny in North West, never planned on becoming a farmer. However, when unfortunate circumstances forced her to take charge of her husband’s operation, she rose to the challenge, and now produces Hereford and Angus cattle, as well as pecan nuts. Pieter Dempsey reports.
Improving the stud one animal at a time
Dirco Swart, owner of Blinkmeneer Beefmasters in Frankfort, says that the future of the Beefmaster is bright, thanks to the breed’s adaptability and breeders’ passion for improvement.
Controlling biting flies
Biting flies are not only a nuisance, but can also transmit diseases and deliver painful bites, says Dr Mac.
A soya bean range for all conditions
Nico Barnard, an agronomist in the central Highveld for Pannar, explains the importance of planting different soya bean cultivars to spread risk. This is how Pannar’s soya bean range can help!
Why plants need nitrogen
This element, which is found in the chlorophyll of plants, is responsible for vegetative growth and is therefore crucial to the success of the crop.
