Abstract:
A field work was carried out at Agronomy field of Sher-e-Bangla Agricultural
University, Dhaka-1207, to study the influence of square spacing system on
the growth and yield of sesame during March, 2015 to June, 2015. The
experiment was laid out in a split plot design with three replications. Two
factors were used those were variety (V
1
= Binatil-2, V
2
= BARI Til-3 and V
=
BARI Til-4) which allocated to main plot and square spacing (S
(control) = 30
cm × 5 cm, S
S
5
2
= 20 cm × 20 cm, S
3
= 30 cm × 30 cm, S
4
1
= 40 cm × 40 cm and
= 50 cm × 50 cm) which assigned to sub-plot. Among the cultivars Binatil-2
well-matched with square spacing and gave the maximum leaf area index
(4.44) at 55 DAE, above ground dry matter weight plant
-1
(60.23 g) at harvest,
capsules plant
1
-1
(124.03), seed weight plant
-1
(18.64 g), seed yield (1.03 t ha
) and harvest index (30.63 %) etc. In the case of different square spacing, the
widest (50 cm × 50 cm) was given the highest above ground dry matter weight
plant
-1
(67.24 g) at harvest, capsules plant
-1
(141.22) and seed weight plant
(19.79 g) whereas control spacing (30 cm × 5 cm) showed the highest crop
growth rate (36.69 g m
-2
d
-1
), seed yield (1.79 t ha
-1
) and harvest index (31.33
%). In combination treatment the highest seed weight plant
-1
(23.39 g) was
taken from Binatil-2 along with the widest spacing (50 cm × 50 cm) while
Binatil-2 with control spacing (30 cm × 5 cm) ranked top in seed yield (1.88 t
ha
-1
). It is clear from the experiment that wider spacing influenced individual
plant with vigorous growth and yield but failed to produce yield per unit area
due to lack of optimum plant population.
