Abstract:
The experiment was conducted through November 2012 to March 2013 in the
Experimental Field of Sher-c-Bangla Agricultural University, Dhaka. Bangladesh to
find out the effect of irrigation, sowing time and variety on different yield
contributing parameters and yield of wheat. The experiment comprised three factors;
Factor A: two irrigations, viz. 1: Irrigation; Jo: No irrigation (control). Factor B: three
sowing times,
viz. S: 18 November. S2: 03 December and 53: 19 December; and
Factor C: four improved wheat varieties,
viz. V = BAR! Gom-21 (Shatabdi),
BAR! Gom-25. V
3 = BAR! Gom-26 and V
4 = BAR! Gom-27. The experiment was
laid out in a Split-split plot design with three replications. Irrigation was assigned in
the main plot, sowing time was in the sub plots and variety was in the sub-sub plots..
Experimental results indicated that the highest grain yields were obtained with I
(2.915 t hi'),
Si
(2.983 t hi') and V, (2.636 t haj. The interaction treatment IS,V
1
showed significantly the highest yield (3.653 t hi') which was attributed to the
maximum values in spikelets spike' (20.22), grains spik&' (66.78), and 1000 grain
weight (47.23 g).
