Advantage of Phosphorus Solubilizing bacteria in bitter gourd

06/02/2019Posted on
  • Increase micronutrients availability to plant from the soil like Mn, Mg, Fe, Mo, B, Zn and Cu in addition to P2O5.
  • Encourage faster root growth for water and nutrient uptake.
  • PSB produce organic acids like malic, succinic, fumaric, citric, tartaric acid and acetic acid which fasten the P2O5 uptake, maturity and increase yield.
  • Increase resistance towards diseases and drought tolerance due to rapid cell development in the plants.
  • Reduce 25 – 30% phosphatic fertilizer requirement.

  • Increase crop yield and the quality of the produce
  • Increase hormones activities
  • Increase Plant growth and root growth
  • Increase photosynthetic activity
  • Increase soil fertility and the effect can be seen on next crop season because of bacterial multiplication and presence.
