The experiment was conducted at Spices Research Centre, Shibgonj, Bogra during rabi season, 2012-13, to determine optimum plant spacing for maximizing seed yield of black cumin. The experiment was laid out in a randomized complete block design with three replications. Six plant spacing viz., T1= 3o cm x 10 cm (33 plants/m2), T2= 25 cm x 10 cm (40 plants/m2), T3= 20 cm x 10 cm (50 plants/m2), T4= 30 cm x 5 cm (66 plants/m2), T5= 25 cm x 5 cm (80 plants/m2) and T6= 20 cm x 5 cm (100 plants/m2) were compared. The highest seed yield (1204 kg/ha) was obtained from 20cmx 10cm spacing which was identical to 30 cm x 5 cm spacing (1083kg/ha) but differed significantly from other treatments. The lowest seed yield (889 kg/ha) was obtained from 25cmx 5cm spacing.

To find out optimum plant spacing for black cumin.
The experiment was conducted at Spices Research Centre, Shibgonj, Bogra during rabi season, 2012-13, to determine optimum plant spacing for maximizing seed yield of black cumin. It was a coordinated program with agronomy division, BARI, Gazipur. The experiment was laid out in a randomized complete block design with three replications. Six plant spacing viz., T1= 3o cm x 10 cm (33 plants/m2), T2= 25 cm x 10 cm (40 plants/m2 ), T3= 20 cm x 10 cm (50 plants/m2), T4= 30 cm x 5 cm (66 plants/m2), T5= 25 cm x 5 cm (80 plants/m2) and T6= 20 cm x 5 cm (100 plants/m2) were compared. The unit plot size was 3m x 4m. The cv. BARI Kalizira 1 was used as a test crop. The crop was sown on 13 November 2012. The seeds were continuously sown in line as per treatmens. In addition to 5 t/ha of cow dung, the crop was fertilized with N100P30K45S20Zn2B1 kg/ha. The entire amount of cow dung, P, K, S, Zn, B and 1/3 N was applied during final land preparation. The rest N was applied in two equal splits at 25 and 50 days after sowing (DAS). Two weeding were done at 30 and 45 DAS. Five irrigations were applied at 25, 35, 50, 70 and 85 DAS. To control foot rot, Bavistin (Carbendazim) @ 2g/L of water was applied at 20, 35 and 50 DAS. Thinning was done at 15 DAE to maintain plant populations as per treatments. The crop was harvested on 28 March, 2012. Data on plant population (at harvest), plant height, number of primary branches per plant. Number of capsules per plant, capsule length, number of seeds per capsule, 1000-seed weight and seed yield was recorded.

Different spacing treatments had a significant effect on the 1000-grain weight of black cumin. The heaviest 1000- grain weight (2.33 g) was recorded from 20cm x 10cm spacing which was identical to 30cm x 5cm spacing. The lowest 1000 grain weight (1.83 g) was recorded from 25cm x 5cm spacing. The seed yield of black cumin varied significantly due to different spacing treatment. The highest seed yield (1204 kg/ha) was obtained from 20cmx 10cm spacing which was identical to 30 cm x 5 cm (1083 kg/ha) but differed significantly from other treatments. Meena et. al. (2011) reported that sowing nigella (Black cumin) at 25cm x 10cm exhibited highest seed yield which was at par with other crop geometry (30cm x10cm or 20cm x 10cm). The lowest seed yield (889 kg/ha) was obtained from 25cmx 5cm spacing.
From the above result it may be concluded that the plant spacing 20cm x 10cm (50 plants/m2) or 30 cm x 5 cm (66 plants/m2) may be good for maximizing seed yield of black cumin.
