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.

Land restitution farms in South Africa have a patchy success rate, with many going to ruins after the change in ownership. Failure is usually attributed to the sudden change in management from those with a farming background to those without, as well as a critical lack of operating capital. Lindi Botha spoke to Tom Mdluli of the Matsafeni Trust about surviving despite the challenges, and their plans to expand the operation.

Xanthomonas campestris can destroy a cabbage plant. It can also occur on dead organic matter under the proper conditions, warns Bill Kerr.

Lowveld farmers have limited options to get around the cost-price squeeze in order to remain profitable amid rising input costs and decreasing crop prices. Father-and-son team Charles and Carel Burger have an innovative approach: they are intercropping coffee and macadamias to maximise returns. Lindi Botha reports.
