Field investigation were carried out to study the effect of planting time, bulb size and bulb spacing on plant growth and seed yield attributes of onion cultivar RO-1 during rabi of 1995-96, 1996-97 and 1997-98 at Agricultural Research Station, Durgapura (Jaipur) of Rajasthan Agricultural University (Bikaner). Maximum seed yield (10.95 q/ha) was obtained in 11th October planting followed by 1 October (10.05 q/ha). The bulb diameter (6.0x4.5 cm) and bulb spacing (45x30 cm) had given maximum seed yield of 9.87 q/ha and 9.76 q/ha, respectively. The maximum net return of Rs. 78145 per hectare and highest cost-benefit ratio of 1.0:3.36 were recorded when 4.5 x 3.0 cm diameter bulbs were planted at 45 x 30 cm spacing on 11 October for seed production of onion cultivar RO-1.
