... of herbicides significantly affected DMA, CGR, and NAR of T. Aman rice at 30, 45, 60 and 90 DAT (Fig. 8). The maximum DMAs (9.2, 27.5, 63.8 and 108.1 g plant −1 at 30, 45, 60 and 90 DAT, respectively), CGR (3.94 mg cm -2 day -1 ), and NAR (7.46 mg cm -2 day -1 ) were recorded in acetochlor 14% + bensulfuron methyl 4% WP treated plots. The minimum DMAs (5.7, 20.9, 49.5, and 90.3 g plant -1 at 30, 45, 60, and 90 DAT respectively) and CGR ...

... the quantity of dry matter accumulation and crop growth rate of rice. The dry matter accumulation (DMA) differs with the varieties due to the differences in leaf area, growth stage, and resources utilization ability of the varieties. In this study, varieties had significant effect on DMAs of T. Aman rice at 30, 45, 60 and 90 DAT and also on CGR (Fig. 8 and Figure 9). BR11 had the maximum DMAs (8.32, 32.61, 74.26 and 125.85 g plant −1 , respectively) at 30, 40, 60 and 90 DAT and the maximum CGR (4.59 mg cm −2 day −1 ). While Chinigura rice had the minimum DMAs (7.18, 15.42, 39.27, and 72.95g plant −1 at 30, 40, 60 and 90 DAT, respectively) and the minimum CGR (2.99 mg cm −2 day −1 ). ...
