Black cumin (Nigella sativa L.; Family-Ranunculaceae) is an important spice crop. Mature seeds are consumed for edible and medical purposes and also used as a food additive and flavour. Seed of black cumin has great potentiality as spice crop due to nutritive and medicinal values. The experiments were carried out at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2011 to 2012 to determine optimum planting time for seed production of black cumin. The experiment was two factorials. Factor A: 4 genotypes were V1: Exotic, Iran; V2: BARI kalozira-1; V3: Local, Faridpur and V4: Local, Natore. Factor B: sowing date: D1: 16 October; D2: 1 November; D3: 16 November and D4: 1 December. Therefore, treatment combinations were 16 in total. So, in 3 replications total plot was 48. Result revealed that significantly the highest 2.37 t/ha in V1, followed by V2 (1.96 t/ha). V2 and V3 (1.97 t/ha) were statistically similar and maximum yield was obtained from D2 (2.65 t/ha). In combined effect, maximum yield 3.00 t/ha was obtained in V1D2.. Investigation on time of sowing revealed that performance of black cumin was better in earlier sowings (16 October, 1 November) than later ones. The highest yield (4g plant^-1; 2.65 tha^-1) was obtained when the crop was sown on 1 November. Among the genotypes, the exotic one with sowing in 1 November gave the highest seed yield (4.54 g·plant^-1; 3.00 t·ha^-1).
