The experiment was conducted at the Spices Research Centre, Shibgonj, Bogra during rabi season, 2010-11 and 2011-12 to find out the optimum planting time and plant spacing for maximizing seed yield of onion. The highest gross return, net return and benefit-cost ratio was obtained from 10 November planting which was closely followed by 20 November planting. Similarly, the highest gross return, net return and benefit-cost ratio was obtained from 20cm x 15 cm plant spacing. In review of the result of the study, it can be concluded that from agronomic and economic point of view crops grown on 10 or 20 November along with 20cm15cm spacing might be the best alternative for maximizing seed yield of onion.

Variety and Species
To determine the planting time with population density for successful seed production of onion.
The experiment was conducted at the Spices Research Centre, Shibgonj, Bogra during rabi season, 2010-11 and 2011-12 to find out the optimum planting time and plant spacing for maximizing seed yield of onion. The experiment was laid out in a split-plot design with three replications. In 2010-11, four planting time viz., 30 October, 10 November, 20 November and 30 November were assigned to the main-plot and five plant spacing viz., 20cm x 20cm, 20cm x 15cm, 20cm x 10cm, 15cm x 15cm and 15cm x 10cm were assigned to the sub-plot to achieve the objectives. In 2011-12, one planting time 20 October was included and one plant spacing 15cmx10cm was discarded from the treatments.
