Four size of onion sets and three planting distance were used for two years of field study. Planting of bigger size of sets (i.e. 3 cm) on wider planting (i.e. 45 × 20 cm) increased bulb diameter, bulb weight and doubles percentage in onion, but the highest bulb yield (170.63 q/ha) and net profit (Rs. 42269 q/ha) with cost-benefit ratio (3.71) was recorded when 2 cm size onion sets were planted on 45 × 10 cm planting distance.
