Abstract:
The experiment was conducted at the field of the Sher-e-Bangla Agricultural
University farm, Dhaka to evaluate the performance of population density and
variety on growth and yield of Rapeseed-Mustard. The experiment consists of two
factors (1) Variety and (2) Population density. Four varieties viz. (i) V
= BARI
Sarisha-13, (ii) V
2
= BARI Sarisha-15, (iii) V
3
1
= BARI Sarisha-16 and (iv) V
=
SAU Sarisha-3 were used and four population densities were used viz. (i) P
=
100000 plants ha
-1
; i.e. 10 plants m
-2
(ii) P
2
= 400000 plants ha
-1
; i.e.40 plants m
(iii) P
3
= 700000 plants ha
-1
i.e. 70
plants m
-2
and (iv) P
4
= 1000000 plants ha
i.e.
100 plants m
-2
.Significant variation was found in all parameters at different
growth stages of rapeseed- mustard. Different varieties showed significant
variation at different stages. Data also showed that V
3
P
(BARI Sarisha-16 × 10
plants m
-2
1
) gave the tallest plant (170.90 cm) but the highest leaf length (29.79
cm), leaf breadth (9.16 cm), length of siliqua (7.94 cm), seeds siliqua
(26.03),
1000 seed weight (4.10 g), seed yield (1.60 t ha
-1
) and harvest index (41.02%)
were found from V
1
P
3
(BARI Sarisha-13 × 70 plants m
-2
) where the highest dry
weight plant
-1
(22.70 g), branches plant
-1
(7.56) and siliquae plant
-1
(145.70) were
found from V
1
P
1
(BARI Sarisha-13 × 10 plants m
-2
). Again, the maximum stover
yield (2.93 t ha
-1
) and biological yield (4.06 t ha
-1
) were found from V
-1
3
P
3
-1

-2
(BARI Sarisha-16 × 70 plants m
-2
) and V
1
P
4
(BARI Sarisha-13 × 100 plants m
)
respectively. Considering individual effect, BARI Sarisha-13 (V
) gave the highest
seed yield (1.35 t ha
-1
), biological yield (3.55 t ha
-1
1
) and harvest index (37.65%)
where P
3
(70 plants m
-2
) gave the maximum seed yield (1.32 t ha
), stover yield
(2.33 t ha
-1
), biological yield (3.48 t ha
-1
) and harvest index (36.14%). So, above
all deliberation, the best result was achieved from the treatment combination of
BARI Sarisha-13 × 70 plants m
-2
(V

P

).
