Introduction

  • Citrus comprises the following broad categories: oranges, soft citrus, grapefruit, and lemons and limes.
  • These can be consumed as fresh fruit or processed for juice making, juice concentrates and dried fruit production. Citrus fruit can also be processed as essential oils obtained from fruit peels.
  • These are used by the flavour houses to add flavour to drinks and food, by pharmaceutical companies, in aromatherapy and by the cosmetics industry.

International business environment

  • The top producers of oranges are Brazil, China, EU, Mexico and Egypt (SA is at number 7) (USDA, 2023).
  • The top exporters of oranges are Egypt, SA, EU, US and Turkey (USDA, 2023).
  • Top importers of oranges are the EU, Saudi Arabia, Russia, Iraq and the UK (USDA, 2023).
  • The top producers of tangerines/mandarins: China, EU, Turkey, Morocco and Japan (USDA, 2023). SA is at number 7, but she is the third largest exporter.
  • The top producers of grapefruit are China, Mexico, South Africa, US and Turkey. SA is the top processor and exporter (USDA, 2023).
  • The top producers of lemons and limes: Mexico, Argentina, EU, Turkey and the US. SA is at number 6. The top exporters are Mexico, Turkey and SA (USDA, 2023).

South Africa: imports and exports

Citrus makes up 59% of South Africa’s fruit exports (FPEF, 2023).

  • In 2022, oranges were exported to Europe (32%), Far East & Asia (23%), Middle East (20%), North America (9%), Russia (8%), and the UK (7%) (FPEF, 2023).
  • Lemons went to Europe (39%), Middle East (29%), Far East & Asia (9%), Russia (7%), UK (8%) and North America (6%) (FPEF, 2023).
  • Grapefruit was exported to Far East & Asia (42%), Europe (35%), Russia (10%), North America (6%), UK (4%) and the Middle East (3%) (FPEF, 2023).
  • Soft citrus went to Europe (25%), UK (19%), North America (16%), Far East & Asia (15%), Middle East (12%) and Russia (10%).

Newly proposed European Union (EU) regulations threaten the export of oranges from the Southern African region to Europe (Burger, 2022). Infrastructure in SA is not geared towards the new demand (e.g. the temperatures required by the new protocol). The potential also exists that several cultivars, organic and non-chemically treated oranges will be disqualified (Fruitnet, 2022; Jansen, 2022, as cited by BFAP, 2022). South African producers and exporters are trying to find alternative markets for produce (BFAP, 2023).

Local business environment

Regions under citrus are climatically diverse. Examples are:

  • the semi-tropical areas of the low-lying eastern seaboard (Zimbabwe, Moçambique, and Limpopo, Mpumalanga and KwaZulu-Natal provinces of South Africa);
  • the higher lying subtropical areas (Nelspruit, Letaba, Zimbabwe middleveld);
  • the cool coastal areas of the Eastern and Western Cape.

The northern and eastern areas of Southern Africa are all summer rainfall areas, whereas the Western and Southern Cape enjoy a Mediterranean-type climate with winter rainfall. In the Eastern Cape a bimodal rainfall pattern exists with rains mostly occurring in spring and the fall. This broad climatic range from semi-tropical to Mediterranean-type climates has numerous, distinct advantages resulting in a wide range of cultivars being successfully produced from late February/early March through to late September/mid October.

Limpopo (40%), Eastern Cape (25%), Western Cape (19%) and Mpumalanga (8%) have the largest production areas for citrus in South Africa (CGA, 2023).

The largest portion of citrus produce (77%) is exported to foreign countries through export agents (CGA, 2023). The balance goers to local fresh produce markets and processing – juice making and dried fruit (BFAP, 2023).

Grower’s points of interest

Citrus Improvement Programme and nursery practices

South African citrus producers purchase their trees from nurseries accredited by the South African Citrus Improvement Scheme (SACIS). The SACIS serves the citrus Industry via a centralised budwood supply farmblock – Citrus Foundation Block (CFB) – near Uitenhage, close to Port Elizabeth. Currently the CFB supplies all certified propagation material to accredited citrus nurseries. A nuclear block of virus-free material of all cultivars is maintained at the Agricultural Research Council-Tropical and Subtropical Crops (ARC-TSC) and at Citrus Research International (CRI) in Nelspruit. All the propagation material, except lemons, has been inoculated with a mild strain of Citrus Tristeza Virus (CTV) to protect the trees against the more aggressive CTV strains that is commonly found in southern Africa.

Rootstocks

Since the 1980s, rootstocks rendering high internal quality fruit (such as Troyer and Carrizo, X639 and MXT citranges, and Swingle citrumelo) have become the rootstocks of choice. This aspect is important for the future competitiveness of the Southern African citrus industry to produce fruit of high eating quality to compete with citrus production regions such as Argentina, Uruguay and Australia where trifoliate orange rootstock is preferentially used due to the cold tolerance it imparts on the scion. Rough lemon rootstock is still the preferred rootstock for lemons. Where Eureka lemons are used, producers are aware of incompatibility with certain citrange rootstocks.

Planting time and procedure

Since most nurseries are producing trees in containers, time of orchard establishment is not critical. However, in the colder, windy areas the preferred planting time is early spring (September/October).

Nursery trees are commonly topped at 60 to 70 cm height to allow scaffold development to occur at a height of 40 to 60 cm. Growers ensure that trees with goose neck root systems are not planted.

Spacing trends

Citrus tended to be ranched in certain areas, especially the hot climatic regions. Due to increased establishment costs and the need for earlier economic break-even, and the need to have sunlight-, spray- and picker-friendly trees, there has been a move towards increasingly higher planting densities. Also, the new wave of technology development in tree size maintenance, particularly pruning, provide citrus producers with more confidence to plant at higher densities.

In the hotter regions, where Valencia oranges and grapefruit are produced, spacings of 7×3 meters or 6×3 meters are commonly used, whereas in the cooler regions, where Navel oranges, and Clementine and Satsuma mandarins are produced, spacings as wide as 6×3 meters and as close as 4.5 or 5×2 meters are used.

Preplant soil preparation

The high potential soils of the northern areas (with little or no need for pH correction) are usually only ripped and land preparation costs are thus quite low. In the Western Cape region a lot of money is spent on proper ripping and ploughing. Soil pH correction and other ameliorants (phosphorus, sometimes micro-elements) are added in a double ploughing action. Expensive subsoil drainage systems are often required. In addition, in many cases ridging is considered to provide for added drainage or where the soil is high in clay content.

In the case of replant soils the previous trees must be removed with their root systems, the soils must be ploughed and dried out properly to allow the incidence of soil borne pathogens such as Phytophthora to diminish, and replanting should only take place two years after the proper removal of the trees if the soils are not fumigated before replanting.

Windbreaks

In certain citrus producing areas windbreaks are necessary to reduce wind blemishes. Many windbreak types have been tested or are commonly used. The most well-adapted windbreak tree throughout Southern Africa is beefwood or Casuarina (Casuarina cunninghamiana Miq.). Pinus radiata D. Don and silky oak (Grevillea robusta A. Cunn) are sometimes used. Deciduous type windbreaks are often used as secondary windbreaks in conjunction with beefwood in the Western Cape, e.g. Dutch alder (Alnus cordata) and Chinese poplar (Populus simonii [syn. P. obtusa]).

Row orientation

Whereas it is not so critical to plant in north-south row directions in the northern regions (lower latitude, dry winters), it is still commonly done. In the more southern latitudes, with the more extreme angle of the sun and where rain or dew can keep the tree wet for extended periods during harvest, it is essential to plant in a north-south row direction, especially with Alternaria susceptible cultivars.

Irrigation and fertigation

Under-tree microsprinkler irrigation systems are most commonly used, while a few orchards still use overhead sprinkler irrigation. More recently, however, drip irrigation systems have become increasingly common, with an increased use of drip fertigation where pH and electrical conductivity are controlled in a balanced nutrient solution which is provided daily to restrict root system development in a bid to control tree phenology. To attain good eating quality, pre-harvest water stress (limited or deficit irrigation) has become an accepted practice, for example with Satsuma mandarin.

Fertilisation

Fertilisation of bearing trees is exclusively based on annual leaf analysis data from leaves from fruiting terminals and the previous history of the orchard with respect to yield, fruit size, quality and previous fertilisation record. Nitrogen phosphorus and potassium are most commonly applied as soil applications, whereas magnesium and the micro-elements (copper, boron, zinc, manganese and molybdenum) are applied as foliar applications, when required. Soil pH correction is achieved by the addition of calcitic or dolomitic lime, and water penetration or salinity problems are addressed by the application of gypsum.

Pruning

In some production regions there is a shift towards selective pruning by hand or with pneumatic pruning equipment. Most large orchards are, however, hedged and topped mechanically. Though higher density plantings are the norm, growers should guard against too dense plantings which could result in crops being pruned away. Managing post prune re-growth is critical.

National strategy and government contact

The National Development Plan (NDP) recognised the potential of commercial agriculture for job creation. In setting its targets for job creation, the NDP recognised:

  • The employment requirement to produce citrus fruit is estimated at one worker per hectare of an estimated 60 000 translating into about 60 000 workers employed on citrus farms.
  • Direct downstream labour requirements for citrus are estimated at one labourer per 2 500 cartons packed: with about 100 million cartons packed per year, some 40 000 jobs are created in packing plants for a period of six months, or 20 000 full-time equivalents.
  • In addition, there are labour requirements for transportation, warehousing, port handling, research and development, and processing

Citrus – like several other labour-intensive sectors like table grapes, apples, macadamias, pecans and avocadoes – has already reached and gone beyond the targets set by the NDP (BFAP, 2020, 2019).

For the country’s champion agricultural export to do better, additional market access and port efficiency are crucial. Both have been given priority under the newly signed Agriculture and Agro-processing Masterplan.
