Abstract:
The experiment was carried out at the research field of Sher-e-Bangla Agricultural
University, Dhaka during November 2019 to May 2020 to study the effect of sulphur on
popular three BRRI released rice varieties. The experiment consisted of three rice
varieties viz., V
1
(BRRI dhan88), V
2
(BRRI dhan89) and V
(BRRI dhan100) in
combination with four sulphur treatments viz., S
0
(control; 0 kg S ha
3
-1
), S
),
S
2
(40 kg S ha
-1
) and S
3
(50 kg S ha
-1
). The experiment was laid out in Randomized
complete Block Design (RCBD) with three replications. Among different rice varieties,
V
(BRRI dhan100) showed better performance on different growth parameters, but
considering yield and yield contributing characters V
3
(BRRI dhan89) exhibited better
performance,whereas V
1
2
(BRRI dhan88) gave the least performance. Among sulphur
treatments, S
2
(40 kg S ha
-1
) gave the best results considering other treatments followed
by S
3
(50 kg S ha
-1
) whereas control treatment S
0
(0 kg S ha
-1
) showed the lowest
performance. In terms of combined effect of variety and sulphur treatment, V
showed
better results regarding yield contributing and yield characters and gave the highest
number of effective tillers hill
-1
(21.67), panicle length (29.87 cm), number of filled
grains panicle
-1
(114.80), 1000 grain weight (24.30 g), grain yield (8.57 t ha
), straw
yield (9.59 t ha
-1
) and harvest index (47.16%), whereas the lowest results were recorded
from V
1
S
0
. Therefore, among the treatment combinations, V
2
S
(BRRI dhan89 with 40 kg
S ha
-1
2
) can be considered as the best treatment combinations followed by V
(BRRI
dhan89 with 50 kg S ha
-1
) compared to other treatment combinations.
