Key Messages

This report examines the nuances of Zero Budget Natural Farming (ZBNF) for select crops - paddy, groundnut, chilli, cotton and maize - in terms of water and energy consumption, emission, yield, and cost of cultivation.

Reduction potential: Water and electricity consumption (50%-60%), life cycle energy consumption (45%-70%), life cycle emissions (55-85%), cultivation cost (10%-40%) in select irrigated crops

Yield: The yield difference between ZBNF and non-ZBNF for chilli and paddy is negligible. For the remaining crops, non-ZBNF exhibits higher yields, with an increase in the range of 0.3–0.7 Mt/acre

Improved farmer income: Reduced dependency on inorganic chemical-based fertilisers shows higher revenue potential, even when yields from select crops are lesser.

Improved health: Reduced dependency on inorganic components promotes healthier farming lifestyle.

Road to sustainability: Promotion of mulching reduces environmentally-damaging practices like residue burning; similarly, multiple aeration method reduces methane emissions from paddy fields.
