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 mungbean to fertilizer and weed managements. The experiment consisted of two
factors, and followed split plot design with three replications.The experimental
treatments with their levels were Factor A: different fertilizer managements with 3
levels (viz; F
1
= recommended dose (RD), F
2
= RD + 1 % urea foliar spray at
flowering, F
3
= RD + 2 % urea foliar spray at flowering) and Factor B: different weed
managements with 4 levels( viz; W
0
and 35 DAS, W
2
= No weed control, W
1
= Release 9EC spray at 30 DAS and W
3
ii
= 2 hand weeding at 15
= Release 9EC spray at 20
and 40 DAS).The experimental results revealed that different fertilizer and weed
managements significantly influenced the yield and yield contributing parameters of
mungbean. Application of recommended dose of fertilizer along with 2 % urea foliar
spray at flowering (F
3
) influenced plant to have greater growth and yield of mungbean.
The highest pods plant
-1
(16.98), pod length (7.55 cm), seeds pod
-1
(10.71), 1000-seed
weight (37.16 g) and seed yield (961.50 kg ha
-1
) were recorded in F
3
(RD + 2 % urea
foliar spray at flowering) treated plot. In case of different weed management, the seed
yield ranges between (799.2-1022.4 kg ha
-1
). The highest seed yield (1022.4 kg ha
)
was recorded in W
1
(2 hand weeding at 15 and 35 DAS) treated plot. In the case of
combined effect of treatments application of RD + 2 % urea foliar spray at flowering
stage along with 2 hand weeding at 15 and 35 DAS (F
3
W
1
) influenced plant growth
and development and recorded the highest seed yield (1159.0 kg ha
) while the
lowest seed yield (575.0 kg ha
-1
) was recorded in the recommended dose of fertilizer
with no weed control treatment (F
1
W
0
)
