Cashew Farming

Cashew farming is a very old and traditional business in many countries around the world. Both price and demand of cashew (cashew nut) are much higher in the market, so it is a highly profitable business.

The cashew tree is actually a tropical evergreen type tree that produces the cashew seed and the cashew apple accessory fruit. And like the tree, the nut is often simply called cashew

The cashew trees are much larger and can grow as high as 46 feet. The largest cashew tree in the world covers an area of 81,000 square feet and is located in Natal, Brazil.

But the dwarf cultivars grow around 20 feet and they are more productive, with earlier maturity and greater yields.

The fruits of the cashew tree is a kidney or boxing-glove-shaped drupe that grows at the end of the cashew apple. The drupe develops first on the tree and then the pedicel expands to become the cashew apple.

The cashew apple is a light reddish to yellow fruit, whose pulp and juice can be processed into a sweet, astringent fruit drink or fermented and distilled into liquor.

Along with the popularity of cashew nuts and fruits, the plant has several other uses. The shell of the cashew seed yields derivatives that can be used in many applications including lubricants, waterproofing, paints etc.

4 million tonnes of cashew nuts were produced globally in the year of 2019, with Ivory Coast and India as the leading producers. Burundi, Vietnam, and the Philippines also had significant production.

However, commercial cashew farming is a very old and popular business. You can make good profits from this business if you can do everything perfectly.

How to Start Cashew Farming

Starting commercial cashew farming is just like starting other fruit farming business. It’s very easy and simple, even the beginners can also start this business easily.

We recommend having practical knowledge before starting this business. Here we are trying to describe more information about starting and operating a successful cashew farming business from planting, caring to harvesting and marketing.

Site Selection

Cashew plants ca be grown in a variety of soil types, but the production will be much better on good/fertile soils. Deep and well-drained sandy loam soils without a hardpan are considered best for cashew farming.

These plants can also thrives on sandy soils, but mineral deficiencies in the plants are more likely to occur. Water stagnation and flooding are not congenial for cashew.

Heavy clay soils with poor drainage and soils with pH more than 8 are not suitable for cashew farming. Excessive saline and alkaline soils are also not good for these plants. Red sandy loam, lateritic soils and coastal sands with slightly acidic pH are best for cashew farming.

Prepare the Soil

Plough the land thoroughly and level it. Total costs of land preparation will vary depending upon the type and method of soil working. Land preparation should be completed during May to June.

Climate Requirement For Cashew Farming

The cashew tree is cultivated in the tropics between 25°N and 25°S, and is well-adapted to hot lowland areas with a pronounced dry season, where the mango and tamarind trees also thrive.

Temperature range between 20°C and 30°C is considered best suited for cashew farming. Cashew needs a climate with a well-defined dry season of at least 4 months to produce the best yields.

Choose a Variety

Many different cashew varieties available to choose from. You can choose the dwarf variety as it is highly productive and start fruiting faster.

Cashew Propagation

Cashew can be propagated by seeds and also vegetatively propagated by grafting. One year old shoots as well as current season shoots (3-5 months old) are used for grafting.

Purchase Plants

If you want to avoid the hassle of propagation, then you can purchase ready-plants from the nurseries. Today, there are many nurseries available for ready cashew plants.

Planting

Planting cashew plants is very easy. But you have to be conscious about the planting space. Generally planting space of 8 meter x 5 meter is recommended.

The trees grow vigorously in the first 3 years and as soon as the crowns touch each other alternate trees should be removed until the permanent planting distance of 10-12 meter is reached.

Caring

The cashew plants are very strong and hardy and they generally require less caring and other management. Although, taking additional care will help the plants to grow well and produce more.

Fertilizing

Application of 10-15 kg of farmyard manure per plant is recommended to ensure adequate organic matter in the soil.

And chemical fertilizers recommended for a mature cashew tree are 1.1 kg urea, 750 grams single super phosphate and 200 grams muriate of potash.

Watering

Watering or irrigation is a very important factor in cashew production, especially during the establishment of young trees. Because, providing adequate irrigation doubles the growth tempo of young trees in a dry season.

Although, the trees can survive several months without irrigation, mainly due to the deep root system. The mature cashew trees should receive 1800 liters of water per tree every 2 weeks.

Mulching

Mulching helps to retain moisture into the soil, and at the same time it helps to control weeds. You can use organic materials for using as a mulch.

Controlling Weeds

In commercial cashew farming, weeding with a light digging should preferably be done before the end of rainy season. Hoeing, cutting the weeds off the underground is more effective than slashing.

Pruning

Branches hanging on the ground should be removed because they interfere with harvesting.

Inter-cropping

Tall growing inter-crops like certain varieties of sorghum and millet should not be encouraged between young cashew plants (because they will provide too much shade).

Leguminous crops such as groundnut and beans are very suitable for intercropping. Cultivation of horse gram, cowpea, groundnut etc. are also recommended as inter-crops in cashew farming.

Pests & Diseases

Like many other commercial crops, the cashew plants are also susceptible to many pests and diseases. There are about 30 species of insects infesting in cashew farming.

Out of these tea mosquito, flower thrips, stem and root borer and fruit and nut borer are the major pests which are reported to cause around 30% loss in yield of cashew nut.

The cashew crop basically doesn’t have any serious disease problem expect the powdery mildew caused by a fungus (which affects the young twigs and inflorescence and makes it wither).

This disease generally appears when the weather becomes cloudy. You can easily control this disease by dusting with 2% sulfur W.P.

Harvesting

Cashew plants start bearing after 3 years of planting, and they reach full bearing during the 10th year and counting giving remunerative yields for another 20 years.

The cashew nuts are generally harvested during February to May. Harvesting generally consists of picking of nuts that have dropped to the ground after maturing.

However, if the apples are also used for making jam, juice, syrup etc. then the fruits have to be harvested before it falls naturally.

Post-Harvesting/Processing of Cashew

Post harvesting tasks or processing of cashew involves these steps

• Preliminary cleaning
• Roasting
• Shelling
• Separation
• Drying
• Peeling
• Grading and
• Packaging

Yield

It’s actually very tough to tell the exact amount. And total yield also depends on numerous factors.

Marketing

Marketing raw cashew is very easy and simple. You will probably be able to sell your products easily in the market. Although, you should set your marketing strategies before starting this business.

These are the common steps and ways for starting and operating a successful cashew farming business. Hope this guide has helped you. Good luck & may God bless you!
