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.Pardeep Kumar*, Savita, Sushil Kumar, Vandana Thakur,
