Context: A two-year field study conducted by Punjab Agricultural University (PAU) scientists on the effectiveness of Liquid Nano Urea has revealed a significant reduction in rice and wheat yields compared to the application of conventional nitrogen (N) fertilizer.
News:
These results highlight the importance of conducting extended, long-term field assessments spanning 5-7 years to determine the equivalence of nano urea to traditional urea and its sustainability in sustaining crop yields.
Key Findings on the Effectiveness of Liquid Nano Urea:
Liquid Nano Urea:
Composition:
- Liquid Nano Urea is urea presented in nanoparticle form, serving as a liquid nutrient alternative to traditional urea for supplying nitrogen to plants.
Characteristics:
- Urea is a chemical nitrogen fertilizer, typically white, providing essential nitrogen, a key nutrient for plant growth.
- The nano urea is engineered to substitute conventional urea, potentially reducing the requirement for the latter by at least 50%.
Concentration:
- A 500 ml bottle of Liquid Nano Urea contains 40,000 mg/L of nitrogen, equivalent to the nitrogen impact of one bag of conventional urea.
Launch:
- Introduced in June 2021, Liquid Nano Urea was launched by the Indian Farmers and Fertiliser Cooperative (IFFCO).
Development:
- Developed domestically at the IFFCO-Nano Biotechnology Research Centre in Kalol, Gujarat, aligning with the principles of Atmanirbhar Bharat (Self-reliant India) and Atmanirbhar Krishi (Self-reliant Agriculture).
Importance:
- Particularly significant as India relies on imports to fulfill its urea requirements.
Application Method:
- Liquid Nano Urea is applied as a foliar spray, intended for use once leaves have emerged on the crops.
