Abstract:
An experiment was conducted at Agronomy Field, Sher-e-Bangla Agricultural University
(SAU), Sher-e-Bangla Nagar, Dhaka-1207 during the period from November 2017 to May
2018 to evaluate growth, yield and grain quality of traditional aromatic rice cultivars in Boro
season. The experiment was laid out in a Randomized Complete Block Design (RCBD) with
three replications. Eleven aromatic rice genotypes viz. T

attributes, yield and harvest index. Chinigura was produced the tallest plant (151.23 cm),
higher number of tillers hill
-1
(25.66), and leaves hill
-1
(65.00). The maximum leaf area index
(5.5) was obtained from Chinigura (T
6
) which was statistically differed from all other
varieties. Days to 50% flowering (92.66 days) was more for Chinigura (T
6
) which was
statistically similar with all varieties except BRRI dhan38 (T
5
= Chinigura, T
7
) and Madhumala (T
7
). BRRI
dhan34 (T
3
) produced the highest chlorophyll content in leaves which was statistically
identical with BRRI dhan38 (T
5
), Chinigura (T
6
) and Chiniatap-2 (T
11
). Grain length and
breadth ratio is the lowest (2.26 : 1) in Kataribhog-1.Chinigura provided the highest grain
yield (3.46 t ha
-1
) followed by Kataribhog-1 (3.32 t ha
-1
), Badshabhog (3.20 t ha
), BRRI
dhan38 and BRRI dhan50 (2.65 t ha
-1
). Chinigura also provided the highest straw yield (8.11
t ha
-1
) and biological yield (11.10 t ha
-1
). So, Chinigura exhibited higher adaptability in Boro
season compared to rest of the cultivars.
