Abstract:
A pot experiment was conducted during the period from June to December 2021 in Aman
season at Sher-e-Bangla Agricultural University, Dhaka to investigate the effect of the
different organic fertilizer on the growth and yield of transplanted aromatic aman rice
varieties.The experiment was laid out in Completely Random Design (CRD) with 2
factor and four replications. Factor A: Different rice varieties (7) viz: V
:
Chinigura, V
3
: Gobindobhog, V
4
: Kataribhog, V
5
: Tulshimala, V

: Kaloshila, V
: Kalijira, V
: BRRI
dhan34 and Factor B: Application of different organic manures (3) viz: T
: 150 g CD
pot
-1
, T
2
: 150 g VC pot
-1
and T
3
: 30 g MOC pot
-1
. For the purpose of evaluating the
experiment's outcomes, data on various parameters were evaluated. Experimental result
revealed that in comparison to other rice varieties, BRRI dhan34 (V
) rice variety
performed best in different organic fertilizer treatments and recorded the highest average
plant height (121.08 cm), effective tiller number hill
-1
7
(10.00), grain weight pot
(17.81
g) and straw weight pot
-1
(37.40 g) comparable to other varieties. Different organic
manure application influenced the growth and yield attributes of transplanted aromatic
aman rice varieties, and the highest average plant height (120.39 cm), effective tiller
number hill
-1
of rice (9.36), grain weight pot
-1
1
of rice (20.58 g) and straw weight pot
of
rice (44.92 g) were obtained in 150 g vermicompost treated pot (T
). In case of
combination, the highest average plant height (128.50 cm), effective tiller number hill
(14.25), grain weight pot
-1
(24.56 g) and straw weight pot
-1
of rice (54.60 g) were
observed in V

T
combination treatment. Therefore, cultivating BRRI dhan34 in
combination with the application of 150 g VC pot

-1
for rice production resulted in a
higher grain weight than the other organic treatments and was suitable for organic rice
production comparable to other treatment combination.
