Abstract: Carrot is a popular cool season vegetable cultivated in tropical region during winter. Carrot belongs to the family Apiaceae with 2n=18. It produces edible root of high quality in one season and seed in two seasons. Seed stalk is produced in second season. It is advisable to plant carrot seed crop at high plant density to ensure more proportion of seed yield with quality seed from primary and secondary order umbels. In this case, proper spacing can be maintained and after-care like weeding and thinning is easier. Prepared stecklings are planted either on flat bed or on ridge. Planting on ridges is more easy and convenient. In addition, there is no fear of water stagnation. The present experiment was conducted at Seed Area, Department of Vegetable Science, and in Laboratory of the Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar (Haryana) during 2016-17 and 2017-18. The experiment was laid out in Randomized Block Design with three replications. There were five treatments of spacing i.e. T₁: 45x45 cm, T₂: 45x30 cm, T₃: 45x15 cm, T₄: 30x30 cm, T₅: Paired row (60x45 cm). The treatment S₅ (paired row) was significantly higher for umbels per plant (11.21), seed yield per plant (17.78 g) and seed yield per hectare (7.51 q), which was statically at par with treatment S₁(45x45 cm).
