Abstract:
The experiment was conducted at the Agronomy field laboratory of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during the period from March to May
2009 to study the effect of Boron and Molybdenum on the growth and yield of
mungbean. The variety BARI mung-6 was used as test crop. The experiment consists of
two factors: Factor A: Boron (4 levels); 0 (B
and Factor B: Molybdenum (4 levels); 0 (Mo

replications. The result revealed that treatment B

showed the highest
plant height (47.22 cm), dry matter plant

(16.68 g), number of pods plant
(30.36),
pod length (8.97cm), seed yield (1.53 t ha

) and stover yield (1.78 t ha
(2 kg

) showed the highest 1000-seed weight (44.28 g). On the other hand, B
(0 kg B

(13.44 g), number
of pods plant

revealed that Mo

but Mo

(2 kg Mo ha

Mo

(0 kg Mo ha

(14.17g), number of pods plant

(24.14), pod length (7.05cm), seeds per pod (8.29),
1000-seed weight (40.31 g), seed yield (1.17 t ha

(18.40), pod length (5.77 cm), seeds per pod (7.43), 1000 seed weight (38.05 g), seed
yield (0.99 t ha
-1
) and stover yield (1.37t ha
-1
). It may be concluded that boron and
molybdenum had a significant influence on the growth and yield of mungbean and 1.5
kg B and 1.5 kg Mo per hectare can be the optimum dose for higher yield of
mungbean.
