The present investigation was undertaken with seven rice varieties to assess their responses to three management practices, namely System of Rice Intensification (SRI), Recommended Practice (RP) and Traditional Practice (TP) towards morpho-physiological and yield parameters. The results indicated that all the cultivars under study performed better under SRI as compared to other two practices with respect to different morphological and yield traits including grain yield. All the cultivars exhibited delayed panicle initiation, increased leaf area, leaf area index and leaf area duration under SRI practice as compared to other two cultivation practices. Among the varieties, PAC 837 recorded the highest grain yield (7.83 t/ha), followed by Arize 6444 (6.55 t/ha) and IR-64 (5.07 t/ha) under SRI practice.
