The experiment was carried out at the “Horticulture Farm” of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from November 2019 to March 2020 to study the influence of phosphorus fertilization and seed rates on yield components and yield of black cumin. The experiment consisted of two factors. Factor A: Four levels of phosphorus viz., P0= control, P1= 35 P kgha-1, P2= 40 P kgha-1 and P3= 45 P kgha-1and Factor B: Three seed rates viz., R1= 8 kg seeds ha-1, R2= 10 kg seeds ha-1and R3= 12 kg seeds ha-1. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on growth, yield components and yield of black cumin and significant variation was observed for most of the studied characters. Growth related data was maximum on P3 (45 P kgha-1) treatment but in case of seed yield, P2 (40 P kgha-1) treatment showed the best result. In case of growth characters, R1 (8 kg seeds ha-1) treatment revealed the best result but in case of seed yield, R2 (10 kg seeds ha-1) treatment showed the best result. The highest seed yield (1.27 t ha-1) was obtained from P2R2 (40 P kgha-1+ 10 kg seeds ha-1) treatment combination. On the other hand, the lowest seed yield (0.94 t ha-1) was obtained from of P0R3 (control + 12 kg seeds ha-1) treatment combination. So, it was revealed that the P2R2 treatment combination appeared to be best for achieving the higher growth and seed yield of black cumin.
