The experiment was conducted at the Spices Research Centre, Shibgonj, Bogra during rabi season 2012-13 to find out the optimum planting time and plant spacing for maximizing seed yield of fennel. The experiment was laid out in RCB design with three replications. Three sowing time viz., 10 November, 20 November and 30 November and six plant spacing viz., 30cm x 10 cm, 30cm x 15 cm, 40 cm x 10 cm, 40cm x 15cm, 50 cm x 10 cm and 50 cm x 15 cm were compared to achieve the objectives. The highest seed yield (1.31 t/ha) obtained from crops planted on 10 November which was identical to 20 November (1.26 t/ha) and the lowest seed yield was recorded from 30 November (0.99 t/ha) sowing. The highest seed yield was found (1.41 t/ha) from 40 cm x 10 cm spacing which differed significantly from other treatments. The highest seed yield (1.55 t/ha) was recorded from 10 November  40cm x 10 cm spacing which differed significantly from other treatments.

For maximizing fennel seed production
The experiment was conducted at the spices research centre, Shibgonj, Bogra during rabi season 2012-13 to find out the optimum planting time and plant spacing for maximizing seed yield of fennel. The experiment was laid out in RCB design with three replications. Three sowing time viz., 10 November, 20 November and 30 November and six plant spacing viz., 30cm x 10 cm, 30cm x 15 cm, 40 cm x 10 cm, 40cm x 15cm, 50 cm x 10 cm and 50 cm x 15 cm were compared to achieve the objectives. The unit plot size was 3m x 1.5m. The advance line FN01 was used as test crop. The crop was planted as per date and spacing mentioned in the treatments. The land was fertilized with cow dung (5 t/ha), N60P20K40 kg/ha. The entire quantity of cow dung, P and K were applied during final land preparation. N was applied in two equal splits. One half was applied at 15 days after germination and the other half of N was applied in flowering stage followed by irrigation. Weeding, irrigation and other intercultural operations were done as per necessary. The crop was harvested on 15 April, 20 April, and 24 April, 2013. Data on plant height, primary branch/plant, umbel/plant, umbel let /plant, seeds/umbel let, 1000 seed weight and seed yield were recorded and analyzed by MSTAT-C software

Only 1000-seed weight and seed yield varied significantly due to interaction between sowing time and plant spacing (Table-3). The highest seed yield (1.55 t/ha) was recorded from crops grown on 10 November with 40cm x 10cm spacing which was identical to 10 November with 40cm x15cm spacing (1.46 t/ha) and 20 November with 40cm x 10cm plant spacing.
In review o the result of the study, it can be concluded that crops grown on 10 or 20 November along with 40cm x 10cm plant spacing might be the best alternative for maximizing seed yield of fennel.
