Abstract
IN 1913 the exports of citrus fruit from South Africa amounted to 70,000 cases; by 1929 this had risen to 1,200,000. At the present time only 22 per cent of the citrus trees in the Union of South Africa are more than eight years old. Citrus groves are established from the Zoutpansberg, in the north of the Transvaal, to Uitenhage, in the extreme south, and Clan William, in the extreme west of the Cape of Good Hope. Such are the very varying climatic and soil conditions under which this young industry is established. There is no well-defined citrus area such as exists in Florida and California. So far as possible, the author has drawn on South African experience, and much information has been collected from the successes and failures of the past. Where South African experience does not exist—and a large amount of research and investigation is shown to be still necessary—the author has of necessity to draw on work done elsewhere.
