Abstract: The present investigation was conducted at Lovely Professional University, Phagwara (Punjab) during rabi season (October 2017- April 2018). The experiment consisted of six treatments of different combination of spacing and nitrogen doses using garlic variety cv. PG-18 laid out in Randomized Block Design (RBD) with three replications. Two spacing S1 (15 cm × 10 cm), S2 (15 cm × 10 cm) and three nitrogen doses N1 (50 kg/ha), N2 (100 kg/ha), N3 (150 kg/ha) were used. Data on plant height, number of leaves per plant, maturity period, neck thickness of bulb, bulb diameter, fresh weight of bulb and bulb yield per hectare were recorded. Among all the treatments, the observed growth parameters viz., plant height was maximum in treatment S1 (34.27cm) and N3 (35.92cm), no. of leaves per plant was maximum in treatment S2 (6.08) and N2 (6.03) and earliness was found in S1 (138 DAS) and N2 (140 DAS), while interaction between spacing and nitrogen level was best in treatment S2N3 observed in plant height (36.16 cm) and combination S1N2 lead to earliness (136 DAS). Yield parameters viz., neck thickness of bulb was observed maximum in S1 (0.94cm) and N3 (0.91cm), bulb diameter was maximum in S1 (2.63cm) and N3 (2.55cm), fresh weight of bulb in treatment S1 (28.28g) and N2 (26.78g), bulb yield was recorded highest in S1 (6.89t/ha) and N2 (5.80t/ha), while interaction S1N3 was found best for yield parameters neck thickness (1.01cm), bulb diameter (2.82cm), fresh weight of bulb (29.86g) and bulb yield (7.05t/ha). On the basis of observation recorded for different parameters, it was concluded that S1N3 (15 cm x 10 cm with combination of 150kg nitrogen per hectare) treatment showed significant variation and found best with respect to quality and yield parameters.
