Field Crops

Irrigated wheat is grown by many South African grain farmers in rotation with summer grains such as maize and soya bean. André du Toit, a senior wheat breeder with Pannar Seed SA, shares his knowledge and experience on how farmers can maximise the productivity, and therefore profitability, of these wheat crops.

According to agronomy expert Leonard Oberholzer, weeds’ resistance to herbicides is expected to be one of the greatest threats to food production in years to come.

Tunnel production may seem a relatively simple and profitable way to farm, but it involves high capital costs and has a narrow margin of error. Nico Laubscher Jnr spoke to Glenneis Kriel about the lessons that he and his team have learnt at Alzanne, near Vredendal, over the years.

Through perseverance and applying strict business principles, Elias Pangane proved that farming could produce a viable income for him. The Hazyview vegetable and macadamia farmer spoke to Lindi Botha about the success that comes from combining passion with grit.

The 2018 Toyota South Africa New Harvest competition winner, Whernit Dirks, formerly worked as a general labourer on a farm in Piketberg. Today he farms wheat, barley, oats, rooibos and a flock of 900 Meatmasters on 1 700ha. He spoke to Jeandré van der Walt about his farming journey.

South Africa imports most of the garlic sold in the country, but the local industry can thrive if farmers work together and produce good-quality crops. Jacques Terblanche of Graceland Garlic Seed explains to Gerhard Uys how producers can optimise garlic production.

Fall armyworm has caused significant damage to croplands in South Africa since first detected in early 2017. However, Dr Annemie Erasmus, a senior researcher of entomology at the Agricultural Research Council’s Grain Crops Institute, writes that an integrated pest management strategy has been shown to be an effective weapon against infestation.

Establishing a healthy orchard starts with choosing the correct plant material. In South Africa’s only laboratory of its type, banana plants are cultivated from tissue culture to produce clones that offer farmers vigorous growth and high yield.

To weather the impact of market fluctuations and extreme climatic conditions, producers have to think strategically about farming. Pieter de Jager spoke to Glenneis Kriel about his strategy.

It is often assumed that implementing no-till production is the immediate next step towards restoring degraded soils. Not so, says Guy Thibaud, a veteran soil scientist with the KwaZulu-Natal Department of Agriculture and Rural Development.

Plant parasitic nematodes pose a serious threat to food security in Africa as they damage crops and hamper production. Dr Nancy Ntidi, a nematologist at the Agricultural Research Council, spoke to Annelie Coleman about the effects these pests have on African leafy vegetables, and how they can be effectively managed.

The availability of improved varieties, mandate contracts and storage infrastructure promise to turn barley into a lucrative option in the Swartland. Gert Claassen, who five years ago started producing barley on a commercial scale, spoke to Glenneis Kriel about this opportunity.

Cotton production in North West can be extremely lucrative, according to Arno Janse van Vuuren, manager of agricultural management at agribusiness NWK. A comprehensive survey by the company shows that the province is well suited to cotton cultivation if production is managed effectively.

A unique microclimate in the southern Eastern Cape has given rise to a niche cropping industry that requires intensive precision production over a five- to seven-year cycle. Sabrina Dean paid a visit to large pineapple producer Mark Harris to find out more.

By switching from micro-irrigation to low-flow drip irrigation, macadamia farmer Dawid de Kock has reduced his irrigation water usage by 50%. With the subsequent savings on electricity, fertiliser and labour, the system has significantly improved his bottom line.

Many people who enjoy lettuce in their salad may not be aware that it can be a fairly challenging crop to grow commercially. Dicky and Koshik Sitaram, whose family have been producing fresh produce for many years in KwaZulu-Natal, shared the lessons they learned with Lloyd Phillips.

Researchers have estimated that, over the past four decades, the world has lost a third of its arable land due to erosion or pollution. Solutions are constantly being sought. Frans Joseph and Mias van der Westhuizen of the Free State Department of Agriculture and Rural Development recently tested the mitigating effect of a simple, inexpensive method to address soil erosion.

Up-and-coming commercial farmer Daniel Maqala is diversifying further by investing in asparagus. Sabrina Dean visited him to find out more about his journey so far.

Efficient in-field mechanisation is a major contributor to higher yield and lower production costs. Unfortunately, mechanisation also means that machinery wheels regularly compact the soil. According to precision farming specialist Ian Beecher-Jones, traffic-induced soil damage can be limited by implementing controlled traffic farming.

Leafroll virus is a serious threat to South Africa’s viticulture industry: it shortens the lifespan of vineyards and has a negative impact on wine quality.
