Abstract:
An experiment was conducted during the period of December 2015 to May
2016 at central agricultural research farm of Sher-e-Bangla Agricultural
University Dhaka-1207, Bangladesh to study the response of hybrid rice
varieties to the System of Rice Intensification (SRI) in Boro season.
Treatment consisted of two factors; factor A consists of three levels of system
of rice cultivation i.e.1. Low land transplant condition (T
), 2. Raised upland
condition (T
2
), 3.Raised transplant condition (T
3
1
); and factor B consists of
five varieties i.e. BRRI hybrid dhan3 (V
1
), Bolaka (V
2
), Moyna (V
), Gold
(V
4
), BRRI dhan45 (V
). Results indicated that the highest values of
vegetative growth i.e. plant height, leaves hill
5
-1
, leaf area index, Chlorophyll
content, tillers hill
-1
, dry matter hill
-1
; yield contributing character i.e. number
of grains panicle
-1
, 1000 grains weight, yield and harvest index were the
highest in low land transplant condition (T
1
) and in BRRI hybrid dhan3 (V
).
The combined effect of T
1
V
gave the best result for all vegetative parameters
and reproductive development. Therefore, low transplant condition (T
1
) with
BRRI hybrid dhan3 (V
) could be the best the combination to get higher
yield.
