Zero Budget Natural Farming (ZBNF)


From UPSC perspective, the following things are important :

Prelims level : ZBNF

Mains level : Debate over efficiency of ZBNF

  • Addressing the COP14 to the UNCCD, PM mentioned that India was “focusing on Zero Budget Natural Farming (ZBNF)”.
  • The National Academy of Agricultural Sciences (NAAS) however, criticised the “unproven” technology of ZBNF citing no incremental value gain to either farmers or consumers.


  • ZBNF is a farming technique that seeks to bring down input costs for farmers by encouraging them to rely upon “natural products”, rather than spending money on pesticides and fertilisers.
  • The concept behind ZBNF is that over 98 per cent of the nutrients required by crops for photosynthesis — carbon dioxide, nitrogen, water, and solar energy — are already available “free” from the air, rain, and Sun.
  • Only the remaining 1.5 per cent to 2 per cent nutrients need to be taken from the soil, and converted from “non-available” to “available” form (for intake by the roots) through the action of microorganisms.
  • The idea is that since these too, need not be purchased, farming remains practically “zero-budget”.

Components of ZBNF

  • To help the microorganisms act, farmers must apply ‘Jiwamrita’ (microbial culture) and ‘Bijamrita’ (seed treatment solution).
  • It uses ‘mulching’ (covering plants with a layer of dried straw or fallen leaves) and ‘waaphasa’ (giving water outside the plant’s canopy) to maintain the right balance of soil temperature, moisture, and air.
  • To manage insects and pests, ZBNF recommends the use of ‘Agniastra’, ‘Brahmastra’ and ‘Neemastra’, which, like ‘Jiwamrita’ and ‘Bijamrita’, are based mainly on urine and dung of Indian cow breeds.

Arguments for

  • Proponents claim this system is also more environment-friendly, since it does not require chemical fertilisers and pesticides.
  • Apart from increasing crop yield and leading to healthier produce, this model can also help prevent farmer suicides.
  • Farmers fall into the debt trap mainly because input cost of agriculture is high, they claim, and ZBNF brings it down.

What is the criticism?

  • Scientists say there isn’t much evidence to support claims of the efficacy of ZBNF, and that giving up modified high-value seeds and fertilizers can actually hurt agriculture.
  • There is no verifiable data or authenticated results from any experiment for it to be considered a feasible technological option.
  • 78 per cent of air is nitrogen, but it is not freely available to plants.
  • Being non-reactive, atmospheric nitrogen has to be fixed into a plant-usable form such as ammonia or urea.
