Macadamia nut: description of culture

Macadamia Tree, up to 15 meters high, grows in Australia, mainly in the wet forests of Queensland. This “king” is also called “Australian nut” or “Queensland nut”. It begins to bear fruit only at the 8th year of its life.

Historical reference

This is a long-lived tree that can produce crops for up to 100 years in a row. The fruits of the tree - nuts - ripen in 6-7 months.

The world learned about this wonderful tree thanks to one researcher, whose name is John McAdam. This nut is named after him.

After this researcher discovered this tree, it was brought to the Hawaiian Islands, which are famous for their excellent volcanic soils, where these trees took root well and felt at their best.

Then for some time this culture for some reason turned out to be forgotten.

Where does macadamia nut grow?

Only starting from the 20s of the twentieth century, they began to show interest in the macadamia nut again, cultivating this most valuable plant.

How does Macadamia grow?

There has been a very strong increase in the area allocated for growing this crop. The geography of its growth itself expanded.

Since the 80s of the twentieth century, the cultivation of this crop has been taking place in Australia (in the states of Queensland and New South Wales), New Zealand, and in Africa (the countries of South Africa, Kenya, Zimbabwe, Malawi). And also in the USA (Hawaii Islands and California), a number of countries from South America (Costa Rica, Mexico, Brazil, Paraguay, Jamaica), and in China.

The largest center for the production of these nuts at the moment is the USA, the Hawaiian Islands. Hawaiian plantations are simply gigantic in size. To this day, macadamia cultivation is developing very dynamically! In 1970, almost 6 thousand tons of nuts were produced. And already in 1986 - almost 20 thousand tons, and already in 1999 - 26 thousand tons.

Currently, the production of this product is 50 thousand tons annually! The dynamics are noticeable. Delivery is made all year round.

The main suppliers of macadamia to the world market are Australia, the USA (Hawaii), South Africa, Brazil, and Costa Rica.

As mentioned above, this is the most expensive nut of all the nuts grown and cultivated in the world.

Currently only two species are grown: Macadamia tetraphylla And Macadamia integrifolia (ternifolia). They differ in the thickness of the shell, some properties of the kernels themselves and the climatic conditions that they need for good growth.

The yield of this crop greatly depends on the variety, soil, and climate in which the tree grows. For example, in Australia the yield from one tree is 45 kg, and in the Hawaiian Islands - 135 kg!

After ripening, the upper skin of the fruit cracks and the nut falls to the ground.
