Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University farm,
Dhaka 1207 during the Kharif-1 season from June 2019 to August 2019 to study the
effect of organic and inorganic fertilizers on the growth and yield of mungbean . The
experimental soil was silty clay loam in texture having p
H
6.1.The experiment was laid
out in Rendomized Complete Block Design (RCBD) with 3 replication .There were 7
treatment where , T

= 50% Recommended chemical fertilizer +4t/ha vermicompost . In case of inorganic
fertilizer levels are contained 50% level of NPK= (10-10-14 kg/ha ) , 75% level of
NPK=(15-15-21 kg/ha ) , 100% level of NPK =(20-20-28 kg /ha ) .Different plant
growth and yield parameters were significantly influenced by different organic and
inorganic level of fertilizer . Application of 75% recommended inorganic fertilizer and 4
t/ha vermicompost in case of T
4
treatment was recorded the maximum plant height
(58.26 cm) , number of branches /plant (1.72) , pod length (9.49) , grain yield (1.54t/ha) ,
and straw yield ( 2.63 t/ha) and the minimum plant height(51.50 cm) , number of
branches /plant (0.95) , number of pods /plant (13.16) , number of seeds /pod (10.23) ,
grain yield ( 0.78 t/ha) and straw yield ( 1.66 t/ha) was recorded from the T
1
treatment
where only 100% recommendation chemical fertilizer was used.. The maximum
significant grain and straw yields were obtained with the treatment combination
T
4
(where, 75% recommended chemical fertilizer + 4 t/ha vermicompost). The minimum
yield of grain and straw yield were obtained with the treatment combination T
1
(100%
recommended chemical fertilizer + 0 t/ha vermicompost).
