Abstract
The experiment was conducted during the period from November 2014 to March 2015 in the
experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka to
find out the effect of different irrigation under varying sowing times on growth and yield of
wheat. The experiment comprised of two factors; Factors A: Irrigation (3 times): I
1
: Irrigation
during heading stage; I
2
: Irrigation after 10 days of I
1
ii
and I
3
: Irrigation after 10 days of I
2
;
Factor B: Sowing time (4 dates at 10 days interval): S
1
: Sowing at 10 November, S
2
: Sowing at
20 November, S
3
: Sowing at 30 November and S
4
: 10 December. The experiment was laid out
in Split Plot Design with three replications. Different times of irrigation were assigned in the
main plot and sowing date was assigned in the sub-plot. Irrigation after 10 days of heading
stage showed better performance in all yield contributing and yield parameters except grain
weight spike
-1
. Combined action of irrigation after 10 days of heading stage and sowing at 20
November (I
2
S
2
) recorded the highest values in 1000 grain weight (60.30 g) and grain yield
(4.06 t ha
-1
) which however was not significantly different with those of I

and
