Abstract:
The pot experiment was conducted at the farm of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka-1207 during the period of October 2019 to
February 2020 to study the effect of different combination of biochar and
vermicompost on yield and seed quality of lentil. Two factors viz., Factor A: two
lentil varieties; V
1
(BARI masur-6) and V
2
(BARI masur-7) and Factor B: Biochar +
vermicompost (6 levels); T
1
(0 ton biochar ha

), T
2
(5 ton
biochar ha

), T
3
(0 ton biochar ha

), T
4
(1 ton biochar ha
-1
+ 4 ton vermicompost ha

), T
5
(4 ton biochar ha
+1 ton
vermicompost ha
-1
) and T
6
(2.5 ton biochar ha
-1
+2.5 ton vermicompost ha
) were
considered for the present study. The experiment was laid out in a randomized
complete block design (RCBD) with three replications. BARI masur-6 (V
1
) and BARI
masur-7 (V
2
) showed non-significant difference between them for most of the yield
and seed quality parameters. Treatment T
5
(4 ton biochar ha
-1
+1 ton vermicompost
ha
-1
) showed the best performance on seed yield and quality and gave the highest dry
weight plant

(63.08), number of seeds pod
(1.79),
number of seeds plant

(6.38 g), harvest index (44.17%) seed germination
(91.50%), shoot length (5.32 cm) and root length (3.22 cm) of seedlings after 12 days
of germination and seed vigor index (781.00) compared to other treatments including
control. treatment combination of V

registered the highest dry weight plant
(10.24

and seed vigor index (793.00) compared to other treatment combinations. So, the
treatment combination, V
