A field trial was carried out at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, to evaluate the effects of different levels of Mahogany biochar on growth parameters, yield attributes, and grain yield of rice BRRI dhan89. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications using fifteen treatments. These ratios comprised various proportions of rice fertilizer (RF) + Mahogany biochar (from 0 to 100% RF and from 50 to 100% biochar). Biochar was added prior to the transplantation of Boro rice. It was found that the least significant difference (LSD) analysis showed that biochar application had significantly affected growth parameters like plant height, tiller number, leaf count, leaf dimensions, and leaf area index at 40, 60 and 80 DAT. The other yield components such as harvest index, grain yield, straw yield, panicle length, number of effective tiller and 1000-grain weight were affected. maximum grain yield (9.82 t ha-1) and harvest index (49.70) were recorded in T1 treatment (100% RF + 100% Mahogany Biochar) and T6 treatment (100%RF + 75% Mahogany Biochar). On the other hand, the least values of harvest index (35.64) and grain yield (3.13 t ha-1) were obtained in T15 (0% RF + 50% Mahogany Biochar). On the basis of the results, T1 (100% RF + 100% Mahogany Biochar) was found effective for achieving the better performance of BRRI dhan89. More detailed research can be conducted to investigate the long-term impacts and the sustainability of biochar application in paddy soil.
