Abstract
The field experiment was conducted at the farm of Sher-e-Bangla Agricultural
University (SAU), Dhaka-1207, during the Rabi season (November - February) of
2015 - 2016 to study the planting geometric effect on growth and yield of rapeseed
and mustard. The experiment was laid out in a split-plot design with three
replications. Two factors of which were variety, (V

= BARI Sarisha-11, V

= BARI
Sarisha-14 and V

= BARI Sarisha-17) allocated to the main plots and the planting
geometry, (S

= 25 cm × 5 cm, S

= 30 cm × 5 cm, S

= 35
cm × 5 cm and S

= 40 cm × 5 cm) which were assigned to sub plots. Data were
collected from the experimental field also recorded during the period from 30 to 75
DAS at 15 days interval and at harvest. Plant height was significantly influenced by
different variety. As varietal effect, BARI Sarisha-11 produced the maximum plant
height (127.36 cm), no. of branches plant
-1
(13.74), siliquae plant
-1
(179.58), 1000
seeds weight (3.46 g), seed yield (1.68 t ha
-1
), stover yield (3.88 t ha
-1
) and biological
yield (5.51 t ha
-1
) at harvest. Number of leaves plant
-1
affected significantly due to
planting geometry with variety. The planting geometry affected significantly on the
number of seeds siliqua
-1
, seed yield, 1000 seeds weight, stover yield, biological yield
and harvest index but showed insignificant difference on siliqua length. The seed
yield varied significantly among varieties. In the case of planting geometry S
3
(30 cm
× 5 cm) showed the highest no. of siliquae plant
-1
(141.13), 1000 seeds weight (3.43
g) and biological yield (4.28 t ha
-1
) however S
2
(25 cm × 5 cm) resulted with the
highest seed yield (1.52 t ha
-1
) and harvest index (37.07 %) only. Although the wider
spaced plants appeared with vigorous growth and yield but failed to produce
maximum yield due to lack of optimum plant population. Among the combination of
treatments, BARI Sarisha-11 ranked top in seed yield (2.15 t ha
-1
), stover yield (4.29 t
ha
-1
) and biological yield (6.44 t ha
-1
) when it was sown with S
4
(35 cm x 5 cm)
planting geometry, where seed yield and stover yield statistically similar to S
3
(30 cm
x 5 cm) geometric arrangement.
