There are about 20 different varieties of species in our country. The major production is done in Jammu and Kashmir.

These AKHROTs are exported to Germany, U.K, Egypt, Netherland, and France. China is one of the largest producers of AKHROTs all over the world. AKHROT is one of the important temperate nut fruits in our country. In India, these are found in different shapes and also in different sizes. These are categorized into 4 categories like thin – shelled, medium – shelled, hard shelled and paper – shelled. All over the world and also in India the demand for the AKHROT is high in local and also in international market.

Exotic varieties:

Soil and Climate requirements for Growing Akhrots:

The soil, which is more suitable for Growing AKHROT is silt or loamy soils and also the soil, which is fertile and rich can be used in Growing AKHROT. The pH level of the soil should range between 6.0 – 7.5. If needed, we can provide the soil with zinc, lime and boron with supplements as this will help the soil from not getting a micronutrient deficiency of the soil.

For growing AKHROT, cool climate can are more suitable. But the crop should be protected from freezing and also from frosting. These AKHROTs will not grow in humid and hot climatic conditions. The temperature that is required for Growing AKHROTs are -2  to – 6˚C the rainfall which is required annually is 800 mm. In hot climatic conditions the shell of the nut and also the yield gets affected.

Land preparation and Planting for Growing Akhrots:

The land should be prepared by removing weeds, stones and also the unwanted material of the previous crop should be removed. The land should be ploughed several times as the soil attains fine tilth and also smooth texture. After ploughing the land, land should be levelling and tillering should be done. After all these the field should be applied with farmyard manure and also with green manure. This will help the soil to improve its organic matter.

We should adopt square planting in plant areas. If we are growing AKHROTs in hilly areas, then we can plant them on hill contours. The spacing which should be used for planting the plants is 12 m * 12 m until the seeds become seedlings. In case of grafting plants we need to plant those 10 m * 10 m space.

Propagation method for Growing Akhrots:

The propagation of AKHROTs can be done through seeds, grafting, rootstocks, planting large size trees.

Seed Propagation: Mostly the AKHROTs are propagated by seeds, we should sow the seeds during the autumn season in the nursery it takes 3 months for the seed to become a seedling and the required temperature for the germination is 2 – 4˚C.

Root stock Propagation: These root stocks or grafted budding scion should be planted in the main field directly. The root stocks which are picked should be taken from the lower part of the tree and these will produce their own root system. As the scions produce upper part of the tree and these AKHROT trees are propagated by budding the root stock from August to September. This grafting taken place during the spring season and then the rootstock produces the leaves.

Manure and Fertilization method in Growing Akhrots:

In the commercial cultivation of AKHROT, once in a year i.e. in summer July – August we should collect the leaves of the tree and send them to the laboratory so that we will now the requirement of nutrients for them. As well as at the time of planting, we should apply the farmyard manure and then we should apply them with  the following:

  • Nitrogen @ 2.15
  • Sodium Phosphorus @ 0.1%
  • Potassium @ 1%
  • Calcium @ 1%
  • Magnesium, Chlorine @ 0.3 %
  • Zinc @ 20 ppm
  • Copper @ 4 ppm

Irrigation methods in Growing Akhrots:

After the transplanting the seeds we need to irrigated the plants. The irrigation for the AKHROT depends upon the soil and also on the weather. For conserving the water we can use drip irrigation. Annually the required irrigation for growing AKHROTs is 1270 mm. The AKHROT tree needs more than 50 % during summer season like June, July and August.

Flowering and Pollination in Growing Akhrots:

The tree of AKHROT has both the flower like male and female flower parts. By the help of the wind naturally the pollen transfer from male flower to female flower. And all the AKHROT varieties are self – fertile.

Intercultural methods in Growing Akhrots:

Weeding: The unwanted weeds should be removed from the surrounding of the AKHROT plants. This will harm the plant by affecting their diseases and pests.

Pruning: Regularly the pruning should be done as the wanted and dead stems should remove. So this will help the plant so that the air penetrates into the plant easily.

Training: The plant should be trained from the seedling itself, and this will also help the plant in occupying less space.

Mulching: The weeded plants can be used for mulching as these plants can conserve the moisture in the soil.

Pest and Diseases control measures in Growing Akhrots:

The pests and diseases that affect the Akhrot crop are:

Pests and their controls:

  • European Walnut Aphis – The intensity of European Walnuts Aphis pest can be controlled by spraying nicotine dust.
  • Aphis – These aphids can be controlled by spraying nicotine sulphate.
  • Codling moth – By spraying the lead arsenate in appropriate amount with water the codling moth can be controlled.
  • Red spider – The red spider can be controlled by spraying dicofol or by wettable sulphur or profenophose or by spiromrsifen.
  • Erinose mite – The intensity of the pest can be controlled by spraying Dimethoate or Kelthane.

Diseases:                   

  • Die back or Winter Injury
  • Walnut blight
  • Crown – gall
  • Mushroom root rot

These can be controlled by natural methods and also sometimes we can use chemical sprays.

Harvesting techniques in Growing Akhrots:

The harvesting of the nuts is done in the months of August – September – October – November. These should be harvested after the 75 % of the nut is spilt from the shell. It is indicated that the fruit is mature completely. The harvesting can be done manually by shaking the tree the nuts that are matured will fall down on the ground.

Post harvesting techniques in Growing Akhrots:

Cleaning: After harvesting the fruits they should be washed and cleaned and then the hulls of the nuts should be removed. When the fruits mature completely they can come off easily.

Sorting: The nut should be sorted as per their size and shape.

Grading: The nuts should be graded as per their quality and colour.

Storage: AKHROTs With shells we can store these nuts up to 2 years.

Packing: These should pack in an air tight cover or boxes. They should be packed properly as they should be sent to the market.

Marketing: These can be marketed properly even in local and also in international market.

Yield of Akhrot or Walnut:
