Macadamia farming profit per acre | macadamia nuts cultivation project report

Macadamia belongs to the Proteaceae family and genus of four species of trees indigenous to Australia. Macadamia is native to North Eastern, New South Wales, Central and South Eastern Queensland. Macadamia is also known as Queensland nut, Bush nut, Maroochi nut, Hawaii nut and Bapul nut. In Australia this fruit is well known as bauple, gyndl or jindilli. 

Australian macadamia seeds were first introduced in Hawaii. Hawaii is a constituent state of the United States of America. Hawaii is the 50th state of the USA which is known for first growing macadamia nuts commercially on a large scale. In 2015 Global production of macadamia was only 160,000 tonnes which is 180,000 short in tonnes. People often ask why macadamia nuts are so expensive? We would say the less production of macadamia is still one of the reasons for most expensive macadamia nuts. South Africa has been the biggest producer of macadamia in the world since 2010.

Macadamia nut tree information 

Macadamia tree information is given below in a few steps so that you understand easily. 

  • Macadamia nut tree height - Macadamia tree height is between 2m to 12m or 7ft to 40ft
  • Macadamia nut tree leaf - Macadamia tree leaves are arranged in verticil of three to six. Verticil or whorl is an arrangement of leaves, petals, semans, carpels that are wrapped around the stem or stalk. Macadamia leaves are 60-300 mm (2-10 in) long and 30-130 mm (1-5 in) broad. 
  • Macadamia nut tree flowers - Macadamia tree flowers are long and slender in shape; they are 50-300 mm (2-10 in) long. Individual flowers 10 to 15 mm long. 
  • Macadamia flower color - Macadamia tree flowers are white, pink or purple with four tepals. 
  • Macadamia nut fruit tree - Macadamia fruit is hard, woody and globose and it contains one or two seeds. It has a hard nutshell that needs good effort to crack. Macadamia tree bear fruit in the 4th to 5th year but on a very small scale. However, macadamia tree fruiting time needs patience and it bears commercial level fruits after 10 to 12 or 15 years.

Macadamia farming costs per acre

Macadamia plant cost - Rs 80 to Rs 200 per plant accordingly 

Macadamia plants in 1 acre - 120 plants 

If Rs 100 per plant then 

Rs 100 x 120 plants = Rs 12000

Planting material cost = Rs 12,000 (242.42 $AUD)

Labor cost - Rs 20,000 (374.04 $AUD)

Land preparation cost - Rs 15,000 (280.53 $A)

Fertilizer and manure cost - Rs 6000 (112.21 $AU)

Plant protection charges - Rs 5,000 (93.52 $A)

Miscellaneous cost - Rs 5000 (93.52 $AU)

Total Cost = Rs 63,000 (1,177.34 Australian dollar)

Macadamia farming profit 

Macadamia price per kg 2021 India - Rs 2500 per/kg  to Rs 4000 per/kg and above accordingly

An average macadamia tree produce 15 to 35 kg per tree per year

Let's take 20 kg macadamia production per tree 

Number of macadamia trees per acre - 120 trees 

Let’s find macadamia nuts produced by 120 trees in 1 year 

120 trees x 20 kg nuts = 2400 kg 

120 macadamia trees will produce - 2400 kg macadamia in 1 year

Macadamia nuts 1 kg price Rs 2500 

Rs 2500 x 2400 kg nuts = Rs 6000000 

Macadamia nut profit per acre = Rs 60 lakh (1,12,131.10 A$ or Australian dollar)

Net profit = macadamia farming profit - macadamia nuts cost in India (farming)

Net profit = Rs 60 lakh (1,12,131.10 $AUD) - Rs 63,000 (1,177.34 $ AUD)

Net profit = Rs 59,37,000 (1,10,997.62 $AUD)

Macadamia nut production per tree

  • Macadamia needs 5 to 6 years to produce fruits commercially
  • Macadamia nut production in India is 1 kg per tree for 5 years 
  • Macadamia nut production Australia is much better 
  • Macadamia tree yields 20 kg per year after 10 years
  • An average macadamia nut production per tree is 15 kg to 35 kg nuts per year
  • Mature macadamia tree can produce 50 kg nuts per year 

How to start a macadamia nut farm

How to grow macadamia treeTo start macadamia nut farms in Australia, India or anywhere you need to grab the basic details of macadamia nut tree cultivation. Details related macadamia cultivation is given below 

Macadamia tree planting spacing per acre

macadamia nuts plant spacing - With the spacing of 8 x 4 meters 120 - 135 trees per acre will be good enough due to much sunlight needed by the trees. So avoid the density in macadamia farming for good growth of the tree. With the spacing of 10 by 10 meter 70-80 macadamia plants can be planted in 1 acre and nearly 350 plants can be planted in 1 hectare.

Varieties of macadamia nut trees

Varieties of macadamia trees are given below 

  • Macadamia tetraphylla - edible macadamia

Best soil for macadamia trees

Soil requirements for macadamias - Well drained sandy loam light soils are the most preferable soil for macadamia cultivation. However, macadamia can also grow in free drainage soils but drainage conditions are best for commercial macadamia production. Moreover, for successful commercial Macadamia farming in Kenya, New Zealand, India or globaly minimum depth of 0.5 meters of friable and well drained soil is indispensable. To minimize the chances of trunk canker disease it is necessary to dig the pit around 1 meter. 

Avoid soils

Soil with heavy clay or rocky soils. 

Macadamia tree soil pH level

Macadamia soil ph level should be between 5 to 6.5

Macadamia temperature requirements

Macadamia temperature climate is classified in various forms that are given below

  • Blossoming temperature for night below 19°C.

Macadamia nut growing conditions

  • Macadamia nut tree growing conditions are given below 
  • Macadamia nut cultivation prefers subtropical conditions.
  • Macadamia nut trees like high summer and low winter temperatures.
  • Sandy loam soil with a good drainage system Is preferred for commercial macadamia cultivation.
  • Sandy loam soil should contain pH level ranging from 5.0 to 6.5.
