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.
