dcterms.abstract	The experiment was conducted in the Research Farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during November, 2019 to June, 2020 to ascertain the role of zinc and sulphur on growth and yield of BRRI hybrid dhan2 (Oryza sativa L.). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Four levels of both nutrients i.e. sulphur and zinc, total 16 treatments were tested in this experiment. Data on different morphophysiological traits and yield were recorded and marked differences were observed in case of individual treatments and in most of the cases combined effect were insignificant. However, the tallest plant (97.3 cm and 101.7cm) at maturity and maximum tillers per running meter (119.58 and 109.75) were recorded at 60 days after transplanting (DAT) with application of 40 kg S and 6 kg Zn dependently. With the advance of stage, dry matter accumulation was increased irrespective of both nutrients treatment, it was not like the leaf area index (LAI) which was decreased after panicle initiation stage. The highest LAI (4.17 and 4.29) at anthesis was produced in the plots treated with 40 kg ha -1 S and Zn at 6 kg ha v -1 singly. But at maturity maximum LAI were achieved from30 kgha -1 S and Zn at 4.5 kg ha -1 discretely. Maximum grain yield (6.13 t ha -1 ) was achieved with combined application of 30kg sulphur and 4.5 kg zinc, whereas corresponding minimum rice yield (3.95 tha -1 ) was recorded with absolute control plots where no application of zinc and sulphur was done during entire experimentation period. In short, BRRI hybrid dhan2 produced the highest number of tillers, the highest number of filled grains panicle -1 . The longest panicle and the highest weight of 1000 grains, and consequently provided the highest grain yield.
