While South African blueberry production is showing double-digit growth, savvy growers warn that first testing the appropriate variety selection for each production area is essential, writes Brian Berkman.

This leafy vegetable is a voracious feeder that requires plenty of nitrogen, and must be protected from frost and eelworm, says Bill Kerr.

Hlobi Yende is part of a new generation of young, energetic female farmers making waves in the agriculture sector. She is leading the charge by defying stereotypes and creating an inclusive space for women on farms.

A carrot plant’s fine roots can reach up to 2m deep. Most farmers do not exploit this potential and irrigate more or less the same as they do for other vegetables, writes Bill Kerr.

GA Erasmus en Seuns Boerdery in the Western Cape Overberg won the award for the best income per hectare for pears at Two-a-Day Awards Ceremony in 2023. George Erasmus and Nico Ferreira spoke to Glenneis Kriel about the farm’s pear production strategy.

With continuous management of the insects that predate on sunflowers, significant success can be attained with this crop, which is suited to growing in the drier parts of South Africa, writes Zunel van Eeden.

The process of eating a litchi reveals a greater truth about the fruit’s production: crack the hard part and reap the sweet rewards. While many have opted out of this journey, litchi farmer André Schoeman has continuously placed his bets on the crop, focusing on timing to get maximum returns.

Carrots have a deep root system and this needs to be taken into account when preparing the soil for this crop, says Bill Kerr.

Addressing the challenge of Russian wheat aphid in South Africa requires a multifaceted approach that combines host-plant resistance and biological, cultural and chemical control.

Potatoes are a notoriously tricky crop to produce, making transformation in the sector extra-challenging. However, through collaboration with Potatoes SA and mentorship, Limpopo farmer Walter Mathidi has boosted production. Lindi Botha reports.

Oedema, bursting cabbages, tip burn and cold damage may cause concern but they can be prevented and managed, writes Bill Kerr.

Cauliflower is very sensitive to a boron deficiency, much more so than other cruciferous crops, writes Bill Kerr.

Kathryn Eybers and Ross Dwyer have transformed a degraded ostrich farm into an economically viable, vibrant healthy ecosystem.

Carrot farming has changed considerably over the past 30 years, making it difficult for new entrants to get into the market, says Bill Kerr.

Farmers know that nitrogen is necessary for growing cabbages and other crops, but many do not fully understand its importance for maximising yields, writes Bill Kerr.

While the presence of weeds strongly influences the pest status of cutworm, the influence of soil moisture on factors such as their biology and behaviour are often overlooked. Entomologist and Bt-maize expert Prof Johnnie van den Berg and Zunel van Eeden, a master’s student at North-West University’s Integrated Pest Management group, have undertaken research on cutworm behaviour, control and insecticide resistance.

This year, Two-a-Day’s Stewart Murray Champagne Orchard Trophy went to a Cripps Red apple orchard at Dunmanway Farm. Owner James Downes spoke to Glenneis Kriel about his exceptional orchard.

Plant breeding has progressed to the point where one can now plant two or three varieties of broccoli over the year, says Bill Kerr.

The macadamia industry has yet to make the quantum leap in yield seen in older industries like apples and citrus. But with a greater focus on genetics, and fine-tuning every step in the production process, tripling macadamia yields could soon be a reality. Lindi Botha reports.

At a Vineyard Workers’ Development course held recently in Paarl, Rosa Kruger and Trix Quixley spoke about the importance of the safe and responsible handling and use of agrochemicals.
