Abstract:
A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during the period from March to June 2021 in Kharif I season, to study the response
of blackgram varieties and different plant spacing. The experiment consisted of two
factors, and followed split plot design with three replications. Factor A:Blackgram
varieties (3)viz:V

-BARI Mash 2, V

-BARI Mash 3, V
-BARI Mash 4 and Factor B:
Different plant spacing (4) viz: S

= 15 cm × 10 cm, S
= 20 cm ×
20 cm, and S
= 30 cm × 15 cm. Experimental results revealed that different varieties
and plant spacing significantly influenced the yield and yield contributing parameters
of blackgram. In case of different blackgram varieties the maximum seed yield (1.49t

treatment and lowest seed yield (0.96 t ha
treatment (BARI Mash-2).The highest yield with BARI
Mash-3 (V
2
) was attributed due to the highest pods plant
-1
(6.52), pod length(5.22
cm), seeds pod
-1
(7.78), 1000-seed weight(42.76 g), biological yield (3.25 t ha
) and
harvest index (45.53 %).However in case of different plant spacing the seed yield
ranges between (0.92 -1.46 t ha
-1
). The highest seed yield (1.46 t ha
-1
) was recorded in
S
4
(30 cm × 15 cm) treatment which was achieved with maximum pods plant
(6.67),
pod length(5.36 cm), seeds pod
-1
(7.40) and 1000-seed weight(44.11 g).In case of
combination, cultivation of BARI Mash-3 (V
) along with 30 cm × 15 cm spacing
(S
4
2
) affected plant growth and yield-contributing characteristics, leading to the
maximum seed yield (1.80 t ha
-1
) compared to other treatment combinations.
Therefore, it is suggested that cultivation of BARI Mash-3 along with 30 cm × 15 cm
spacing (V
2
S
) could be as optimum in crop management for maximum yield harvest
in blackgram.
