Abstract
An experiment was
conducted at the Sher-e-Bangla Agricultural University during the
period from Aman season (June-December 2014) with a view to study the
performance of local and modern T. Aman varieties under drought
stress condition imposed at post emergence period. The experiment
comprised of 16 varieties, 12 local viz. (i) Kartik Shail, (ii) Doodh
Kalam, (iii) Nakhuchi Mota, (iv) Kartik Balam, (v) Lal Mota, (vi)
Kalo Khaia, (vii) Changshai (viii) Basmati Shakkar Khanna, (ix) Dholi
Chikon, (x) Ghashful Chikon, (xi) Moulata; and also and four modern
varieties viz. (xii) BRRI dhan34, (xiii) BRRI dhan33, (xiv) BRRI
dhan62 and (xv) BU dhan1.The experiment was laid out in a RCBD design
in field (non-stressed condition) and completely randomized design in
pot experiment (stressed condition). Each treatment both in pots and
field was replicated three times. In stressed condition, at the time
of harvest, the highest weight of 1000-grains (29.60 g) was found in
Moulata. In non-stressed condition, at the time of harvest, the
highest weight of 1000-grains (32.07 g) was found in Rani Salut. In
stressed condition Moulata produced the highest grain yield hill−1
(24.59 g) while in non-stressed condition, BRRI Dhan62 produced
highest amount of grain yield hill−1 (61.75 g). In stressed
condition, the highest harvest index (32.49%) was observed in BRRI
Dhan34 whereas, in non-stressed condition, the highest harvest index
(56.92%) was observed in BRRI Dhan62.
