| Abstract | ||
| The purpose of the investigation was to determine how biochar affected the yield of Boro rice cultivars, including growth dynamics, and yielding characteristics. The investigation was performed at Sher-e-Bangla Agricultural University in Dhaka. Two elements made up the experiment's treatments, such as factor A: Biochar treatment (B0=No Biochar, B1= Rice husk + cowdung Biochar, B2= Mango Biochar, and B3= Me-hogoni Biochar) and Factor B: (V1= BRRI Dhan100, V2= BRRI Dhan89, V3= BRRI Dhan84, and V4= BRRI Dhan69). Three replications were used in the tests, which were conducted according to the RCBD design. Prior to boro transplanting, biochar was added to the soil. Plant height, tillers and leaf number, leaf length, leaf breadth, leaf area index at 40, 60, and 80 DAT, as well as harvest and effective and non-effective tillers, panicle length, filled and unfilled grains, weight of 1000 grains, grain yield, straw yield, and harvest index of rice are all greatly impacted by the variety, the biochar and its interaction effect. Variety V3 (BRRI dhan89) outperformed the other four varieties in terms of rice yield, growth qualities, and yield attributes. The results showed that compared to other biochar treatments, applying the appropriate dose of biochar B3 (Mehogoni biochar) demonstrated increased growth and yield potential. In conclusion, using variety V3 and biochar B3 together can be regarded as an effective agricultural technique for enhancing rice development and grain yield. | ||
