Zero Budget Natural Farming Impact on Tribal Rabi Rice Farming: Economic Analysis

Abstract

This study examines the economic viability of implementing Zero Budget Natural Farming (ZBNF) interventions in rabi rice cultivation, focusing on cost-effectiveness and productivity outcomes. Data collected before (2014-15) and after (2018-19) ZBNF adoption in a selected tribal area of Visakhapatnam district of Andhra Pradesh, India were analysed. Results reveal a reduction in total variable costs by 10.20 per cent, primarily attributed to decreases in weeding and nutrient supply expenses. Despite a slight increase in operational costs, ZBNF led to a significant drop (51.30 per cent) in input expenditures. Yield experienced a notable 10.25 per cent increase, resulting in a decrease in production costs from ₹1161.23 to ₹934.34 per quintal. The calculated cost-to-benefit ratio of -1:1.17 demonstrates favourable economic outcomes, highlighting the potential of ZBNF to enhance economic viability and sustainability in rabi rice cultivation among tribal farmers.
