Rice-azolla produced the most grain, which was at par with rice-fish-azolla-calotropis system. Rice-fish-azolla-calotropis system was more profitable than rice alone, recording an additional income of US$40.70/ha and the highest benefit-cost ratio (1.30) of the systems studied. Rice yield was slightly less under rice-fish system because of the trenches; the fish harvest, however more than compensated for the reduced rice yield. This study indicates that rice-fish-azolla farming is possible in low-lying ricefields of Tamil Nadu
