Abstract:
A field experiment was conducted at the Agronomy field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from
June to October 2009 to find out the performance of some hybrid and inbreed
rice varieties in T. Aman season. The experiment comprised of one factor 14
varieties viz. (i) BRRI dhan31, (ii) BRRI dhan32, (iii) MHR- 1, (iv) MHR- 2,
(v) MHR- 3, (vi) MHR- 4, (vii) MHR- 5, (viii) MHR- 6, (ix) MHR- 7, (x)
MHR- 8, (xi) MHR- 9, (xii) MHR- 10, (xiii) MHR- 11 and (xiv) MHR- 12.
The experiment was laid out in Randomized Complete Block Design (RCBD)
with three replications. At the time of harvest, the longest plant (123.00 cm),
numbers of leaves hill
-1
(32.65), highest number of unfilled grains panicle
(83.77) and 1000 grain weight (27.34 g) were achieved by MHR- 8, BRRI
dhan32, MHR- 10 and MHR- 1 respectively. But in terms of highest tiller
number hill
-1
(12.67), dry matter weight hill
-1
(44.92 g), number of effective
tillers hill
-1
(10.40), panicle length (28.05 cm), number of filled grains panicle
(161.10), grain yield (5.46 t ha
-1
), straw yield (5.86 t ha
-1
) and harvest index
(48.27%) were obtained by MRH- 4 and that of second highest performance
was found in MHR- 3.
So, MRH- 4 and MHR- 3 can be considered as the best
variety under the present study.
