Abstract:
An expernient was conducted at Sher-e-Bangla Agricultt rat University. Dhaka- 1207
tAt, rim! the Rabi season ( )ctober to February) of 2005-2006 to study the effect at' different
levels of nitrogen a nd phosphorus oil the yield, yield contributing characters and seed qua! iv

(Brass/cc: ('cunpextris)
line SAIJ-C-177
. The experiment
comprised of four levels of nitrogen viz. 0. 60. 120 and ISO kg N ha" and four levels of
phosphoi'us viz. 0. 60. 90 and 120 kg P

complete block design (factorial) with three replications.
Nitrogen showed significant effect oil yield, yield components and oil yield of
