Abstract:
An experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural
University, Dhaka during from Rabi, 2017-18 to investigate the yield performance
of mustard and rapeseed varieties as influenced by different planting methods and
different levels of biochar. The experiment was laid out in three factors Randomized
Complete Block Design (RCBD) with three replications. There were 12 treatments
(2 variety × 2 planting method x 3 levels of biochar). The varieties treatments were
V
1
= BARI Sarisha-11 and V
2
= BARI Sarisha-14. Planting methods were P
1
= Line
Sowing and P
2
= System of Mustard Intensification (SMI) at 30 x 30 cm
(transplanting). Biochar treatments were B
0
= Control (No biochar application), B
1
=
application of biochar 5.00 t ha
-1
and B
2
= application of biochar 10.00 t ha
. Results
revealed that highest plant height (137.60 cm) was achieved at the combination of
BARI Sarisha-11 with SMI method and 10 t ha
-1
of biochar. Highest number of
siliquae plant
-1
(440.3) was achieved at the BARI Sarisha-11 with SMI method and
10 t ha
-1
of biochar. Maximum siliqua length (5.74) and seeds siliqua
(33.57) was
achieved with the combination of BARI Sarisha-14 with SMI method and 10 t ha
of biochar. Highest weight of 1000-seed (3.49 g) was found at the combination of
BARI Sarisha-11 with SMI method and 10 t ha
-1
of biochar. Highest grain yield
(2.75 t ha
-1
) were obtained by the combination of BARI Sarisha-11 with SMI method
and 10 t ha
-1
of biochar. Maximum harvest index (30.18%) was obtained at the
combination of BARI Sarisha-14 with SMI method and 10 t ha
-1
-1
-1
of biochar.
