Abstract:
A field experiment was carried out at the research field of Sher-e-Bangla
Agricultural University, Dhaka during the period of March to May 2016 to study
the influence of molybdenum on growth and yield of mungbean varieties. The
treatments were three mungbean (Vigna radiata) varieties viz. BARI mung-5 (V
),
BARI mung- 6 (V
2
) and BU mug-4 (V
) and five molybdenum doses viz. Control
(M
0
), 2g/kg seed (M
1
), 4g/kg seed (M
2
3
), 6g/kg seed (M
4
) and 8g/kg seed (M
). The
experiment was laid out into Split-plot design with three replications where
varieties were assigned in the main plot and molybdenum in the sub-plot. The
purpose of this experiment was to evaluate variations between the mungbean
varieties developed by two different institutions and to study the possibility of
increasing yield by molybdenum application. Data on different yield contributing
characters, growth and yield were recorded. Interaction between varieties and
molybdenum showed a positive impact on growth, yield and yield attributes of
mungbean. Varieties showed no significant variations on plant height, number of
nodules plant
-1
, dry weight, number of pods plant
-1
, number of seeds pod
, first
flowering, pod yield, seed yield, husk yield, stover yield, biological yield and
harvest index. Pod yield, seed yield, husk yield, stover yield, biological yield and
harvest index was unaffected by molybdenum application. Interaction between
variety and molybdenum doses significantly influenced pod yield, seed yield,
stover yield, biological yield and harvest index of mungbean. Seed yield (1210.83
kg/ha), stover yield (3338.00 kg/ha), biological yield (4.55 t/ha) was higher in

teatment. It may be
concluded that interaction between variety and molybdenum doses had a
significant influence on the growth and yield of mungbean.
