Abstract:
An experiment was carried out in the research plot of Sher-e-Bangla Agricultural
University in Dhaka from February to June 2022, to explore how leaf clipping and
variety affected mungbean growth and yield. The treatments included three leaf
clipping techniques, C
0
=No leaf clipping (control), C
1
= 33% Leaf clipping (Removal
of one leaflet), C
2
= 66% Leaf clipping (Removal of two leaflet) and four mungbean
varieties, V
1
= BARI Mung-5, V
2
= BARI Mung-6, V
3
= BARI Mung-7, V
4
= BARI
Mung-8. A two-factor randomized complete block design (RCBD) followed with three
replications was used to set up the experiment. Leaf clipping, variety and their
interactions had a significant effect on the growth, yield and yield components of
mungbean. The tallest plants (13.82, 26.45, 40.77, 58.34 and 62.4 cm at 15, 25, 35, 45
and 55 DAS respectively) were obtained from C
1
V
4
(BARI Mung-8 with 33% leaf
clipping). The highest pod length (10.03 cm), the maximum number of pods plant
(16.63), the highest number of seeds pod
-1
(12.47) were obtained from C
1
(BARI
Mung-8 with 33% leaf clipping) treatment combination. The maximum seed size (52.55
mg) was obtained from C
1
V
2
(BARI Mung-6 with 33% leaf clipping) treatment. The
highest seed yield (2.09 t ha
-1
) was obtained from C
1
V
3
(BARI Mung-7 with 33% leaf
clipping) treatment, while the lowest (1.07 t ha
-1
) from C
2
V
2
(BARI Mung-6 with 66%
leaf clipping) treatment combination. Most of the parameters performed at their peak
in case of BARI Mung-7 and BARI Mung-8. In most of the cases 33% leaf clipping
demonstrated the best performance in terms of growth, yield and yield contributing
characters. In case of combined effect, BARI Mung-7 with removal of one leaflet (33%
leaf clipping) provided the best results followed by BARI Mung-8 with removal of one
leaflet (33% leaf clipping) in terms of growth, yield and yield contributing parameters.
Keywords: Mungbean, Leaflet clipping, Yield, Growth, Variety.
