A field experiment was conducted to study effect of plant density and foliar spray of nutrients on carrot (Daucus
carota L.) seed yield and quality during winter season of 2012-13 and 2013-14. Plant height, days to 50% flowering,
number of umbels/plant, number of seeds/umbel, seed yield/umbel, percentage contribution of different order umbel
to total seed yield, seed yield/plant, seed yield/ha, 1 000 seed (mericarp) weight, germination (%) and vigour index
were recorded. Significant highest average plant height, earliness in days to 50% flowering and seed yield/ha (12.9
q) were observed in high plant density (13 plants/m2). More number of secondary (11.6) and tertiary umbels (30.1)
and higher seed yield/plant (25.2g) were recorded in low plant density (4 plants/m2). Per cent contribution of primary
umbel to total seed yield was maximum (41.76%) in 13 plants/m2 and minimum (16.89%) in 4 plants/m2. But an
increasing trend in contribution percentage to total seed yield by secondary and tertiary umbels was recorded from
13plants/m2to 4plants/m2.Seeds from primary and secondary umbels recorded high quality in plant density of 5 plants/
m2 and 4 plants/m2 respectively.Comparative reduction in pooled seed vigour was observed in 7 plants/m2 and 13
plants/m2. Foliar spray of 0.1% MgSO4at 30 and 60 days after transplanting (DAT) increase the seed quality. Both
seed yield and qualityincrease was observed in 0.1% borax spray at 30 and 60 DAT.
