Richness estimators (Chao 1 and Ace) and diversity indices of Shannon-Wiener (H′) and Simpson from bacterial communities sampled from floodwaters during reproductive and vegetative stages of rice using 16S amplicons. A 3% nucleotide dissimilarity was used for OTU discrimination.

| Vegetative | 25,981 | 8,483 | 7,348 | 1,551 | 2,282 | 2,266 | 5.77 | 0.03 |
