PSB for Jackfruit Trees

Why PSB is Important for Jackfruit Trees

Jackfruit trees require proper phosphorus nutrition for strong roots, healthy flowering, and better fruit formation. PSB (Phosphate Solubilizing Bacteria) helps unlock fixed phosphorus from the soil and makes it easily available to trees.

Major Advantages of PSB in Jackfruit Farming

Better Root Development

PSB encourages deeper and stronger root systems, helping jackfruit trees absorb more nutrients and water.

Improved Flowering

Regular PSB application supports healthy flowering and reduces flower drop in jackfruit orchards.

Bigger and Healthier Fruits

PSB improves nutrient uptake, which helps increase fruit size, fruit weight, and overall fruit quality.

Enhances Soil Fertility

It increases beneficial microbial activity and improves long-term soil health naturally.

Reduces Chemical Fertilizer Use

Using PSB can lower the need for chemical phosphorus fertilizers, reducing farming costs.

Suitable for Organic Farming

PSB is eco-friendly and widely used in organic jackfruit cultivation.

Best Methods to Apply PSB in Jackfruit Orchard

1. Soil Mixing Method

  • Mix PSB with compost or farmyard manure
  • Apply around the root zone of trees
  • Irrigate after application

2. Drip Irrigation Method

Liquid PSB can be supplied through drip irrigation for better nutrient availability.

3. Sapling Root Dip Treatment

Before transplanting, dip jackfruit sapling roots in PSB solution for better establishment.

Ideal Time for PSB Application

  • During plantation stage
  • Before flowering season
  • After pruning operations
  • At active vegetative growth stage
  • During monsoon for better microbial activity

Recommended PSB Dosage for Jackfruit Trees

Application Type Recommended Dose
PSB Powder 2–5 kg per acre
Liquid PSB 1–2 litre per acre
Sapling Treatment As per nursery recommendation
