Abstract:
The experiment was carried out at the Research Farm of Sher-e-Bangla Agricultural University,
Dhaka-1207 from November, 2016 to May, 2017 to study effect of plant growth stimulator and
foliar fertilization on modern rice varieties. The experiment was laid out following Randomized
Complete Block Design with three replications. Two Rice varieties (BRRI dhan29 and BRRI
dhan45) and five combinations of plant growth stimulator and foliar fertilization management (i)
Recommended fertilizer dose; (ii) Recommended fertilizer dose + Akota (iii) Recommended
fertilizer dose + Global; (iv) Recommended fertilizer dose + Akota + Global and (v)
Recommended fertilizer dose + Akota + Global. Data were recorded on different growth
characters and yield contributing parameters. Most of the parameters were showed significant
among the treatment means. In case of variety the highest (101.67 cm) plant height at harvest,
panicles hill
-1
(16.71), filled grains panicle
-1
(192.83), total grains panicle
-1
(199.26) and grain
yield (7.28 t ha
-1
) was recorded from BRRI dhan29. In case of PGS and fertilizer treatment, the
highest values were recorded from T
4
(Recommended fertilizer dose + Akota +Global ) for all
growth and yield attributing characters at different DAT. Due to this T
4
treatment effective tillers
(95.75 %), Panicles hill
-1
(17.65), total grains panicle
-1
(178.0), 1000 grains weight (28.39g),
grain yield (7.36 t ha
-1
) was recorded. Due to the interaction the highest value of plant height
(103.6 cm), number of tillers hill
-1
(18.03) was recorded from BRRIdhan29 × T
4
(Recommended
fertilizer dose + Akota + Global) at harvest. The highest value of all yield attributing characters
including grain yield (7.63 t ha
-1
) was recorded from BRRI dhan29 × T
4
(Recommended
fertilizer dose +Akota + Global). So, BRRI dhan29 and T
4
(Recommended fertilizer dose +Akota
+Global) treatment together had superiority for growth and yield over the other treatments.
