An experiment was laid out in a factorial RBD with three replications involving two lots (unsprayed and sprayed at 45 and 60 days) and eight bulb priming treatments. Bulbs after 1/3rd cutting were primed with zinc (0.5 and 0.75%), magnesium (0.5 and 0.75%), calcium (0.5 and 0.75%) and GA3 (50 and 100ppm) for 6 hours and kept in 1% carbendazim solution for 15 minutes. Bulbs were planted in plot at a spacing of 60 x 30 cm as per treatments along with control. The observations on germination, days to 50% flowering, height of stalk, number of umbels, circumference of umbel, days to maturity, per plant yield (g), seed yield per hectare (kg), germination percentage and seedling vigour of harvested seed were recorded. In the study it was revealed that sprayed lot (foliar spraying at 45 and 60 days) performed well over unsprayed lot for seed yield. Among the treatments, calcium (0.75%) at par with calcium (0.5%) was significantly superior over other treatments for seed yield. Treatment with GA3 (100 ppm) recorded minimum days to maturity while calcium (0.75%) treatment required maximum days for maturity. The seed quality parameters viz. germination percentage and seedling vigour recorded superiority of sprayed lot (foliar spraying at 45 and 60 days) over unsprayed lot.
