The massive improvement in yields has been largely due to new hybrid maize varieties developed by scientists of the Ministry of Agriculture. They have evolved strains capable not only of resisting leaf blight and lodging, but also of returning grain yields comparable with those of the world’s major maize-producing countries.
At the Salisbury Research Station, the major breeding centre, no fewer than 1 400 new hybrid maize varieties have entered preliminary yield trials. Just over a year ago, Rhodesia achieved a spectacular maize yield of 220 bags/ha from experimental fields at the Henderson Research Station, and in the field, farmers have obtained yields of 175 bags/ha. The country’s national average yield per hectare last year was 36 bags. The world record is held by Canada with a national yield of 58 bags/ha, but it is possible that the current Rhodesian crop will break this record.
SR-52 HYBRID
Top of the trial list in Rhodesia is the SR-52 single hybrid. Demand for this white dent variety is enormous, and its popularity is not confined to Rhodesian maize producers. It is also in great demand by growers in South Africa, where massive crops of this variety are now regularly produced. Interest in it has also extended to neighbouring territories and as far afield as Canada and the US.

New farmers' seedling pitfalls
Inexperienced farmers may be tempted to grow seedlings from seed themselves, but they have much to gain by trusting a seedling grower at a nursery to perform this task for them instead
South African avocado production: a success story
Avocado production in South Africa has expanded markedly since the industry's humble beginnings over 80 years ago. From a small grove planted in 1938 in what was then Nelspruit, the industry has blossomed to seven million trees planted on 20 000ha. Dr Guy Witney, project manager at Great Brak Avos, spoke to Annelie Coleman about the country's avocado production.
Unlocking value through livestock exports
Exporting livestock might sound like a daunting business that's better left for big companies, but Gerrie Ferreira, who farms near Oudtshoorn in the Western Cape, has been doing it successfully for almost 30 years, sometimes in partnership with other breeders. He spoke to Glenneis Kriel about the huge potential this market holds, and offers some advice for farmers who are contemplating going this route.
