Abstract
The experiment was conducted in the research field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka from November, 2017 to
May, 2018 to study growth and yield performance of inbred and hybrid rice
varieties in aerobic condition season. Total 10 inbred and hybrid rice varieties
were used in this experiment and they were BRRI hybrid dhan2, BRRI hybrid
dhan3, BRRI dhan28, BRRI dhan29, Binadhan 8, Binadhan 10, Tia, Moyna,
Nobin and Heera 2. The single factor experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications. Data were recorded on
different yield attributes and yield and statistically significant variation was
observed for different rice varieties. The tallest plant (109.65 cm) and maximum
number of tillers hill
-1
(15.70) was observed in BRRI hybrid dhan3, whereas the
shortest plant (91.19 cm) and minimum number of tillers hill
(9.67) was
recorded in BRRI dhan28. At 30, 50 and 70 DAT (days after transplanting), the
largest leaf area (36.48, 45.67 and 49.84 cm
2
) and total dry matter m
(177.05,
546.13 and 875.16 g) was recorded in BRRI hybrid dhan3, whereas the smallest
leaf area (25.53, 32.33 and 37.50 cm
2
) and lowest total dry matter m
(117.84,
347.43 and 752.66 g) was observed in BRRI dhan28. At 30-50 DAT, the highest
CGR (18.45 g m
-2
day
-1
) was recorded from BRRI hybrid dhan3, whereas the
lowest CGR (10.84 g m
-2
day
-1
) from Nobin. At 50-70 DAT, the highest CGR
(16.45 g m
-2
day
-1
) was recorded from BRRI hybrid dhan3, while the lowest
CGR (9.32 g m
-2
day
-1
) from Heera 2. At 30-50 DAT, the highest NAR (7.85 g
m
-2
day
-1
) was recorded from BRRI hybrid dhan3, whereas the lowest NAR (5.10
g m
-2
day
-1
) from Nobin. At 50-70 DAT, the highest NAR (2.76 g m
) was
recorded from Tia, while the lowest NAR (1.60 g m
-2
day
-1
) from Heera 2. The
maximum number of effective tillers hill
-1
(12.33), was recorded in BRRI hybrid
dhan3, while the minimum number (6.13) was found in BRRI dhan28. The
highest spikelets fertility (93.82%) was recorded in BRRI hybrid dhan3, whereas
the lowest (82.35%) in BRRI dhan28. The highest grain yield (5.17 t ha
) and
highest straw yield (5.89 t ha
-1
) was recorded in BRRI hybrid dhan3, while the
lowest grain yield (2.48 t ha
-1
) and lowest straw yield (3.72 t ha
-1
) was found in
BRRI dhan28. Above finding revealed that the BRRI hybrid dhan3 was superior
from other in relation to crop growth characters, yield contributing characters
and yield of rice.
