Abstract:
An experiment was carried out to investigate the effect of nitrogen and phosphorus on the
yield and yield attributes of sesame cv. I3ARI Til-2 at the Field Laboratory of Slier-c-
Bangla Agricultural University. Dhaka-1207. The experiment comprised four levels of
nitrogen viz, no nitrogen (N), 30kg N ha
S ' (N1
), 45 kg N ha' (N
2
). 60kg N ha" (N
3
) and
four levels of phosphorus viz. no phosphorus (P). 60 kg P
205
(111
). 70 kg 1?105
ha''
(P2
) and SO kg P
2 05
ha''(P). The experiment was laid out in a Randomized Coniplete
Block Design (factorial) with three replications. Results revealed that /itrogen
significantly increased yield and yield conirihutiug characters of sesame. Anionu the Four
levels of nitrogen the second highest level i.e. 45 kg N h
a a
performed best in obtaining
the highest values in almost all the parameters such as Number ol'hranches plant''(2.29),
Number of capsule plan('(33. 8
) ). length of capsule (2.32 cm), Number of seeds
capsule"(65.02). seed yield
pl ant !(4.
179), seed yield ha'1316.67 kg)e Phosphorus also
showed significant effect on yield and yield attributes of sesame. Like nitrogen
phosphorus at the second highest level i.e. 70 kg P
205
ha"produeed the highest values in
all the studied parameters except the height of plant. /Ihe lowest values in the studied
parameters were obtained front the control treatmen. C'omhiiied effect of nitrogen and
phosphorus also showed significant effect on y
i
eld and yield attributes except number of
capsules plant and 1000 seed weight. Nitrogen at the rate o145 kg ha'' witl) 70 kg P
2O
ha'' produced the highest values in the studied parameters and in the interaction effect
lowest values were obtained from the control treatment combination.
