PWOnlyIAS

August 28, 2024

A two-year field experiment on the efficacy of nano diammonium phosphate (DAP) by scientists from the Punjab Agricultural University (PAU) has found a substantial decrease in wheat yields compared to conventional nitrogen fertiliser application. 

In the study

  • The experiment revealed a significant decline in wheat yields compared to conventional nitrogen fertilisers.
  • The study observed a decrease in plant height and nutrient content in wheat grain and straw, impacting protein production.
  • When 100% Recommended dosage of phosphorus (RDP) was combined with two sprays of nano DAP, the yield was almost similar to that of traditional DAP.
  • Total plant uptake of nitrogen and phosphorus was lower with nano DAP (17.58 kg/ha) compared to traditional DAP (26.60 kg/ha).

About Nano DAP

  • Nano fertilizer developed by IFFCO using nanotechnology.
  • Contents – 8% nitrogen, 16% phosphorus vs 18% N, 46% P in regular DAP.
  • 500ml nano-DAP equals 50kg conventional DAP.
  • Nano-DAP cost ₹600/bottle vs ₹1350/50kg for subsidized DAP.
  • IFFCO has 20-year patent – entitled to 20% royalty on global usage.
  • Manufacturing facilities in Kalol, Kandla (Gujarat) and Paradeep (Odisha).
  • Expected to reduce annual subsidy bill on non-urea fertilizers.
  • Provides benefits to farmers, industry players across production and distribution chain.

About DAP or Di-Ammonium Phosphate

  • Di-ammonium Phosphate popularly known as DAP (46% P, 18% Nitrogen)  is a preferred fertilizer in India because it contains both Nitrogen and Phosphorus which are primary macronutrients and part of 18 essential plant nutrients.
  • It is the second most commonly used fertilizer in India after urea. 
  • It is thus applied just before, or at the time of sowing.
  • It is rich in phosphorus (P) that stimulates root establishment and development. 

Indian Farmers Fertiliser Cooperative Limited (IFFCO)

  • It was founded in 1967.
  • Headquarters: New Delhi.
  • It is one of India’s biggest cooperative societies which is wholly owned by Indian Cooperatives and is a multi-state cooperative society.
