Haphazard and inappropriate plant spacing and poor soil fertility management practices are among the major factors constraining onion production. Therefore, a field experiment was conducted in Lovely Professional University from November 2017 to April 2018 to assess
the influence of spacing (15×10cnm, 15×10cm and 10×10cm) and different nitrogenous fertilizers (Urea, Calcium nitrate and N:P:K mixture) on growth, yield, and quality of onion. The experiment was laid out in a randomized complete block design (RCBD) of with three replications. Significant difference was observed among all the treatments. The tallest plants (63.67cm) were obtained from the treatment with N: P: K applications well as those spaced at 10 cm intra and inter row spacing. Nitrogen fertilizers and spacing interacted significantly to influence all parameters. Thus, nitrogen fertilizer across the increasing spacing significantly increased number of leaves (30 DAT) fresh bulb weight and bulb diameter. The highest value of plant height (30, 60, and 90 DAT) and number of leaves (60, 90 and 120 DAT) were observed from the application of calcium nitrate and plant spacing of 15×10 cm. whereas total bulb yield was highest in T1S2 (18.53T ha-1). It can be concluded that the highest benefit with low cost of production was obtained in response to the application of nitrogen fertilizers (urea & calcium nitrate) and spacing (15x10cm & 10x10cm) was optimum for producing the crop in the limited area.

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.
