PSB for citrus crops


Citrus crops such as orange, lemon, mosambi, mandarin, kinnow, grapefruit, and lime require balanced nutrition for healthy growth and quality fruit production. Among all nutrients, phosphorus plays a major role in root development, flowering, and fruit formation.

Most phosphorus present in soil remains unavailable to plants. PSB helps unlock this fixed phosphorus and converts it into plant-available nutrients naturally.

PSB = Phosphate Solubilizing Bacteria

These are beneficial soil microorganisms that:

  • Dissolve unavailable phosphorus in soil
  • Improve nutrient absorption
  • Increase microbial activity
  • Enhance soil fertility naturally

PSB acts as a natural nutrient booster for citrus orchards.

Top Benefits of PSB for Citrus Crops

✔ Improves Root Strength

Healthy roots absorb more nutrients and water, resulting in stronger citrus plants.

✔ Boosts Flowering

PSB improves phosphorus availability which supports heavy flowering and better fruit setting.

✔ Increases Fruit Size & Shine

Regular PSB use helps produce:

  • Bigger fruits
  • Uniform fruit size
  • Better peel color
  • Attractive market quality

✔ Enhances Sweetness & Juice Quality

Citrus fruits become juicier and sweeter due to better nutrient utilization.

✔ Reduces Chemical Fertilizer Use

PSB lowers dependency on DAP and synthetic phosphorus fertilizers.

✔ Improves Soil Fertility

Beneficial microbes increase soil health and maintain long-term productivity.

✔ Suitable for Organic Farming

PSB is eco-friendly and ideal for organic citrus cultivation.

Citrus Crops That Benefit from PSB

PSB is highly effective in:

  • Orange farming
  • Lemon cultivation
  • Mosambi farming
  • Mandarin orchards
  • Kinnow cultivation
  • Grapefruit farming
  • Lime plantations

Best Application Methods of PSB

1. Soil Application

  • Mix PSB with compost or FYM
  • Apply near root zone

2. Drip Irrigation Application

  • Liquid PSB can be used through drip systems for uniform distribution

3. Root Dip Treatment

  • Citrus saplings can be treated before transplanting

Best Time to Apply PSB in Citrus Crops

For maximum results apply during:

  • Planting stage
  • Vegetative growth
  • Before flowering
  • Fruit development stage
  • After pruning

Recommended Dosage

Type Recommended Dose
Liquid PSB 2–5 Liters per Acre
PSB Powder 2–4 Kg per Acre

Dosage may vary depending on soil fertility and orchard age.

Why Citrus Farmers Prefer PSB

Farmers choose PSB because it:

  • Improves citrus yield naturally
  • Enhances fruit quality
  • Strengthens soil fertility
  • Improves nutrient efficiency
  • Reduces farming cost
  • Supports sustainable agriculture
