Abstract:
A field experiment was carried out at the research field of Sher-e-Bangla Agricultural
University, Dhaka during the period of March to June 2017 to study the effect of variety
and management packages on growth and yield of blackgram. The experiment comprised
of two factors; Factor A: Variety (3) viz. BARI mash-3 (V
1
), BARI mash-2 (V
) and
BINA mash-1(V
) and Factor B: management packages (3) viz. Low management:
Fertilizer 0-0-0 NPK + 40 kg seed/ha in broadcasting + no pesticide application + no
weeding (M
1
3
), medium management: Fertilizer 20-10-20 NPK kg/ha + 24 kg seeds/ha in
line sowing (30cm×continuous) + pesticide application + one hand weeding after 15 DAS
(M
), high management: Fertilizer 40-20-40 NPK kg/ha + 24 kg seed/ha in line sowing +
pesticide application (ripcord) + two hand weedings at 15 and 25 DAS (M
2
). The
experiment was laid out in split-plot design with three replications. Data on different
growth parameters, yield attributes and yield of blackgram were significantly varied for
different parameters. The highest emergence percentage (33.44%), plant height (53.54
cm), number of leaflet plant
-1
( 19.89), dry weight (8.95 g plant
-1
), branches plant
(2.22),
1000-seed weight (33.74g) and seed weight (0.58 t ha
-1
) was found from BARI mash-2.
The management packages resulted highest emergence percentage (41.11%), plant height
(79.39 cm), leaflet plant
-1
(52.13), dry weight plant
-1
(8.95g), branches plant
(3.00) and
seed yield (0.63 t ha
-1
) from high management (M
3
). The highest leaflet plant
(56.8 cm)
was revealed in V
2
M
3
, and the highest seed yield (1.06 t ha
-1
) and higher harvest index
(49.75) was obtained from V
2
M
. From the above results it was appeared that BARI mash2
with high
management
provided
the
best
yield
attributes
and
yield
of blackgram.
