  • Context (IE | TH): Interim budget announced the expansion of the application of Nano DAP on various crops in all agro-climatic zones.

DAP (di-ammonium phosphate)

  • DAP is the second most used fertiliser in India after urea.
  • Water soluble, containing 18% Nitrogen and 46% Phosphorus, applied before or at sowing time.
  • Manufactured by reaction of Ammonia with Phosphoric acid.
  • Nitrogen is a major component of chlorophyll, essential for photosynthesis.
  • Phosphorus helps in root establishment and development.

Nano DAP

  • Liquid fertiliser with 8% Nitrogen and 16% Phosphorus by volume launched by IFFCO.
  • It has the advantage of a high surface area, as its particle size is less than 100 Nanometres (nm).
  • Nano size enables the fertiliser “to enter easily inside the seed surface or through stomata and other plant openings,” making it more efficient.


  • Intended crop Benefits: Higher seed vigour, more chlorophyll, photosynthetic efficiency, better quality and increase in crop yields.
  • Sustained release: With 50-75% delayed release, Nano DAP will help throughout the plant cycle.
  • Water solubility: It helps in targeted delivery and reduces leaching.
  • Subsidy relief: Less costly Nano DAP will help the government reduce fertiliser subsidies.
  • Easy to use: 500ml bottle is easier to transport, store and use than 50kg bags.
  • Self-reliance: Domestic Nano DAP is expected to ease the import burden of conventional DAP.
  • Allocation for the Fertilizer subsidies has decreased to ₹1,64,150.81 crore (2023-24).
  • The total food subsidy has increased to ₹2,05,250 crore for the Pradhan Mantri Garib Kalyan Anna Yojana (PM-GKAY) and ₹1 lakh crore for the Sugar Subsidy payable under the Public Distribution System from the last budget.
