Abstract
A field experiment was
conducted at Sher-e-Bangla Agricultural University Farm, Dhaka, Bangladesh
during the rabi season from October 2010 to April 2011 to evaluate the influence of nitrogen (N) on the growth and
yield of onion (Allium cepa)
cv. Taherpuri. Treatments of the experiment were four doses of nitrogen (0, 60,
90 120 kg ha-1). The results
showed that plant height and number of leaves at different days after
transplanting, dry weight of leaf, pseudostem and root were increased
significantly with application of nitrogen (N). Nitrogen increased the length
and diameter of bulb, fresh and dry weight of bulb and bulb yield. However, bulb yield did not show any
significant differences between the use of 120 and 180 kg N ha-1.
Therefore, the use of 120 kg N ha-1 may be applied to grow onion.
