The video provides an overview of macadamia nuts, including their uses, varieties, cultivation methods, and costs associated with farming in India. It also covers the harvesting, post-harvest management, and storage of macadamia nuts, highlighting their profitability and the care needed to maintain quality.
Introduction to Macadamia Nuts Farming
Welcome to Discover Agriculture! In this post, we will explore the fascinating world of macadamia nuts. These high-energy nuts are commonly used in the preparation of cakes, confectionery, ice creams, salads, and roasts. Let’s dive into the details of macadamia cultivation, particularly focusing on macadamia farming in India.
Understanding Macadamia Nuts
What are Macadamia Nuts?
Macadamia nuts belong to the Proteaceae family and are native to Australia. They are also known by various names such as Queensland nut, bush nut, maroochi nut, Hawaii nut, and bauple nut.
Varieties of Macadamia
There are only two edible varieties of macadamia nuts:
- Macadamia tetraphylla
- Macadamia integrifolia
Macadamia Tree Characteristics
Tree Growth and Appearance
The macadamia tree can grow between 2 to 12 meters (7 to 40 feet) in height. Its flowers can be white, pink, or purple with four petals. The fruit is hard, woody, and globose, usually containing one or two seeds encased in a hard shell that requires significant effort to crack.
Fruit Bearing
A macadamia tree typically starts bearing fruit in the fourth to fifth year on a small scale. It’s important to note that the cutting propagation method is much faster than seed propagation. Seed propagation can take 10 to 12 years to produce fruits, whereas cutting propagation takes only 4 to 6 years.
Macadamia Farming in India
Choosing the Right Variety
For successful macadamia farming in India, selecting the best variety is crucial. The cost per plant ranges from ₹80 to ₹100. On average, you can plant around 200 macadamia trees per acre.
Farming Costs and Profitability
The price of macadamia nuts in India (as of 2021) ranges from ₹2,500 to ₹3,000 per kilogram. Each tree produces an average of 15 to 35 kilograms of nuts per year. Commercially, the yield in India is about 1 kilogram per tree for the first few years. However, in Australia, a mature macadamia tree can yield 20 kilograms per year after 10 years of growth.
Harvesting and Post-Harvest Management
Harvesting Period
Macadamia nuts are typically ready for harvest from late May to July. The harvesting period may vary depending on the variety, and nuts are often picked by hand or swept up mechanically. A long pole can also be used to carefully knock down mature nuts that are out of reach.
Post-Harvest Management
1. Dehusking: Dehusking should be done within 24 hours of harvesting, followed by the drying process.
2. Drying: The objective of drying is to produce crisp, light-colored nuts free from blemishes. Drying should start with ambient air, followed by a gradual increase in temperature, not exceeding 60°C in the final stage. It’s essential to protect the dried kernels from moisture and oxygen to maintain quality.
Storage
Hard unshucked nuts: These provide protection against insects during storage.
Shelled nuts: These are susceptible to insect damage and should be kept in cold storage, especially for long-term storage, to prevent infestations.
