    Scientific Classification

    • Common Name: Almond
    • Botanical Name: Prunus dulcis
    • Family: Rosaceae
    • Origin: Central and South-West Asia
    • Type: Deciduous tree
    • Lifespan: 30–40 years

     

    Importance & Uses

    • Almonds are nutrient-rich and contain proteins, healthy fats, vitamins (E & B), and minerals (calcium, magnesium, potassium).
    • They are used in the food industry (chocolates, bakery, confectionery, and oil extraction).
    • Almond oil is used in cosmetics and pharmaceuticals.
    • It has medicinal properties—good for brain health, heart health, and skin care.

     

    Major Producing Countries

    • Top Producers: USA (California), Spain, Iran, Italy, Australia
    • In India: Himachal Pradesh, Jammu & Kashmir, Uttarakha

     

    Introduction

    • Almond (Prunus dulcis) is a highly valued nut crop belonging to the Rosaceae family.
    • It is rich in proteins, vitamins, minerals, and healthy fats.
    • It is mainly grown in temperate and Mediterranean climates.

     

    Climatic and Soil Requirements

    Climate

    • Almond requires a Mediterranean climate with:
      • Cool winters (300–600 hours of chilling below 7°C for dormancy and flowering).
      • Warm, dry summers for fruit development.
    • Susceptible to late spring frost; avoid frost-prone areas.

    Soil

    • Well-drained, sandy loam or loamy soil is ideal.
    • Soil pH: 6.0–7.5.
    • Avoid saline, waterlogged, or heavy clay soils.

     

    Varieties

    Self-compatible Shalimar, Mukhdoom, Waris, Pranyaj

    Self-incompatible (Require Cross-Pollination) Nonpareil, Carmel, Drake, Peerless, IXL, Neplus

    Indian Varieties Kagzi, California Paper Shell

     

    Propagation Methods Almond is propagated through vegetative methods such as:

      • T-budding
      • Tongue grafting (on peach, plum, or wild almond rootstocks)

     

    Land Preparation and Planting

    Land Preparation

    • Deep plowing and harrowing to ensure proper root penetration.
    • Land should be leveled to facilitate irrigation.

    Planting Time December–February (Dormant season).

    Spacing

    • Low-density planting: 6m × 6m (277 trees/ha)
    • High-density planting: 4.5m × 3m (740 trees/ha)

    Pit Preparation

    • Pit size: 1m × 1m × 1m.
    • Fill with a mixture of FYM (Farm Yard Manure) and topsoil before planting.

     

    Orchard Management

    Pollination

    • Most almond varieties require cross-pollination.
    • Honeybee colonies (5–8 per hectare) enhance pollination.

     

    Irrigation

    • Almond trees require regular irrigation, especially during:
      • Flowering and fruit set.
      • Kernel development.
    • Drip irrigation is recommended to save water.

     

    Mulching

    • Organic mulching helps in:
      • Moisture conservation.
      • Weed control.
      • Soil temperature regulation.

    Training and Pruning

    Training System Open center or modified leader system is commonly used.

    Pruning

    • Conducted during the dormant season to:
      • Maintain tree shape.
      • Improve sunlight penetration.
      • Remove dead or diseased branches.

     

    Pest and Disease Management

    Major Pests

    Pest

    Symptoms

    Control Measures

    Almond Leaf Roller (Archips argyrospilus)

    Rolls and feeds on leaves

    Spray neem oil or insecticides

    Aphids

    Sucks sap from young leaves and shoots

    Use insecticidal soap or neem-based formulations

     

    Major Diseases

    Disease

    Symptoms

    Control Measures

    Blossom Blight

    Flower rot and fruit drop

    Spray copper-based fungicides

    Root Rot

    Wilting and yellowing of leaves

    Use resistant rootstocks, ensure good drainage

     

    Harvesting and Post-Harvest Handling

    • Harvesting Time September–October (when hulls split open).
    • Harvesting Method Hand-picking or mechanical tree shaking.
    • Drying Sun-dry for 7–10 days to reduce moisture to 6% before storage.
    • Storage Store in cool, dry conditions to prevent mold and insect infestation.

     

    Yield

    • First bearing: 3–4 years after planting.
    • Economic yield: From 6th year onward.
    • Average yield: 10–15 kg/tree (Mature tree).
    • Lifespan: 30–40 years.
