Conservation agriculture (CA) stands out as a recognized alternative to conventional tillage methods, aiming to conserve natural resources while delivering various farm benefits. A field experiment on Kharif rice was conducted during 2019–2020 at the BCKV Farm, Balindi, West Bengal. By integrating different tillage techniques, such as zero, reduced and traditional methods, along with considerations for crop residue quantity and fertilization. CA practices were constructed to minimize energy expenditure for crop cultivation. The performance of these practices was evaluated using diverse indicators encompassing energy usage, benefit-cost ratio, soil criteria, crop criteria (Agronomic) and plant protection criteria. Three multi-criteria decision-making methods (MCDM), namely (i) Analytic Hierarchy Process (AHP), (ii) Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and (iii) Weighted Sum Model (WSM) were applied to identify and validate the most suitable tillage approach for Kharif rice. TOPSIS ranked reduced tillage as the top choice for Kharif rice cultivation, followed by conventional tillage. The same was validated by WSM by deriving the similar ranking. This underscores the potential for promoting and adopting reduced tillage as a viable alternative. AHP played a crucial role in establishing the relative importance of various criteria, ensuring the reliability of decision-making processes. By pinpointing areas for improvement, particularly in addressing weak links, the integration of AHP and TOPSIS facilitated decision-makers in discerning the effects of different criteria on Kharif rice under various CA regimes. This approach provides valuable insights for optimizing agricultural practices and enhancing overall performance. It will assist stakeholders in making cost-effective decisions to improve crop productivity and promote eco-friendly farming practices.
