Jaco Fivaz, farm manager of Mohlatsi farm in Limpopo, is a pioneer of high-density mango orchards, which achieve a greater yield per hectare than conventional orchards. Pieter Dempsey visited this award-winning grower to find out more about his passion for experimentation, and how he manages a diverse mango business.

Jaco Fivaz has a wealth of experience in mango production and has been the farm manager on Mohlatsi farm near Hoedspruit in Limpopo for the past 17 years.

Jaco Fivaz是一家高密度芒果果园的先驱,他在竞标时种植以增加每公顷产量。

“人们始终联系我们希望直接从工厂或生产设施购买,因此我们决定创建一个单独的空间来销售各种各样的产品,如achars,mango mustard和chutneys,以及芒果烛台。”


“However, I soon became more involved with pruning instead of post-harvest research,” he says. After this, he worked as a researcher at Westfalia Technological Services and in 1998 started at Bavaria Fruit Estate, where he first started farming mangoes.

Fivaz believes that the key to growing good-quality mangoes is to plant the trees in sandy and rocky soils.

“I don’t believe in stressing the trees and it’s easier to apply nitrogen in sandy soils rather than heavy soils,” he says.

Mohlatsi farm covers 350ha, and 150ha of these are under production. When Fivaz arrived here in 2004, only 45ha were planted to mangoes, but the area under production has been expanding ever since.

The farm’s fertilisation programme is managed by two companies, Omnia Fertilizer and
Loskop ICT, on different blocks.


The normal fertilisation programme includes ammonium sulphate for nitrogen, potassium sulphate, calcium nitrate, boron and zinc. The total amount of nitrogen supplied during a year is usually about 80kg/ha.

The majority of the mango trees on the farm are spaced at 6m x 1m. This, says Fivaz, is not typical for the industry and the dense planting helps achieve higher yields per hectare without sacrificing quality.

“行业标准约为6m x 2米。不是每种品种都可以在这样的高处生长

For the Tommy Atkins cultivar, he plans to implement a 6m x 1,5m or 6m x 2m spacing, for the Keitt cultivar a 5m x 1m spacing, and for the Sensation and Lormey cultivars a 4m x 1m spacing.


Production management

“The blocks are farmed and managed independently. We decide on a block-by-block basis whether the fruit will be used for processing or fresh marketing.”

They spray the block only after it has been scouted for pests, adjusting the spraying programme to each block.

“We’re very light on chemicals, as there are many valuable insects in the orchards,
such as bees, that we need to protect.”

Environmental management takes a high priority and they work at eradicating invasive


The farm receives between 400mm and 500mm of rainfall per year, and also draws
water from the Lower Blyde River water scheme. Irrigation is carried out six days a week, with micro-irrigation used for mature trees and drip irrigation for young orchards. The micro system delivers between 38ℓ/tree/day and 45ℓ/tree/day and drip irrigation 16ℓ/tree/day to 20ℓ/tree/day.

所有品种跨越农场的平均产量在20t / ha和22t / ha之间,但Fivaz与Keitt品种设定了85t /公顷。平均断裂均匀的产量在18T /公顷相当高,生产成本可以是R80 000 / HA和R90 000 /公顷的密集操作。

“I’m convinced that we haven’t yet reached the ceiling for maximum yield for mangoes. There’s room for growth; it’s possible to achieve 100t/ha.”

He adds that they are currently running one of the largest cultivar and selection evaluation
programmes in the Southern Hemisphere.

“We’re doing this evaluation in conjunction with the ARC’s Institute for Tropical and
registration and released to mango growers.”

export, they use it sparingly, applying it as a drench application directly to the soil.

Pruning plays an important role in achieving higher yield. The trees are pruned in the same
manner as fruit trees in the deciduous industry, with pruning systems such as the central

“Ideally, pruning should be done throughout the year, but cash flow constraints make this difficult to achieve,” says Fivaz.


A performance incentive scheme is in place, and long-term employees are offered certain benefits. For example, permanent employees in the achar factory who have been with the company for more than 10 years are given profit shares in the business unit.


“It’s very important to do research about the type of cultivar you plant and to ensure that
it’s suitable for the area where you farm.
