Abstract:
An experiment was conducted at the Agronomy Field, Sher-e-Bangla
Agricultural University Ohaka during the period from April to June 2007. The
experiment was designed to study the efIbct of different nitrogen level and spacing on
growth and yield of sesame. The experiment consisted of four nitrogen levels viz.
No
0. N, = 30, N
2
= 60 and N3 = 90 kg ha
-1
and four levels of spacing viz.
Sj = 30 cmx Scm;
S2=
30cm x 10 cm: 53 = 40 cmx
5 cm and S4
= 40 cmx 10 ent.
The experiment was laid out in a split plot design with three replications. Sesame
variety 1-6 was used in the experiment. The result showed that nitrogen and spacing
had significant influence on crop characters viz plant height, number of leaves plant",
above ground dry weight, number of branches plant". number of capsules plant',
number of seeds capsule". 1000-seed weight. seed yield, stover yield, biological yield
and harvest index. The highest seed yield (1102.00 kg ha") was recoded from
30 kg N ha" and the yield decreased with further increase in nitrogen rates. Plant
spacing of 30 cm x 10 cm (333333 plants ha") influenced plants to have maximum
seed yield (1010.00 kg ha"). Population either lower or greater then 333333 plants ha"
gave lower yield. Optimum population for 30cm x 10cm nourished with 30 kg N ha'
registered maximum seed yield (1405.00 kg ha"). It was evident that higher seed yield
was obtained due to aggregation of yield components like capsules plant", seeds
capsulc"and 1000-seed weight which farther Justified with the increased value of
harvest index.
