Abstract
A field experiment was conducted at the
Agronomy research field, Sher-e-Bangla Agricultural University, Dhaka,
Bangladesh during November 2012 to March 2013 in rabi season with a view to find out the optimum sowing date for
maximum growth and yield of wheat varieties. The experiment was carried out
with three wheat varieties i.e.
BARI Gom 21, BARI Gom 23 and BARI Gom 24; and five different sowing
dates viz. 10th November; 20th November; 30th
November; 10th December and 20th December of 2012 following
Randomized Complete Block Design (RCBD) with three replications. The results
revealed that among the wheat varieties BARI
Gom 24 performed best recording the highest grain yield (4.51 t ha-1).
On the other hand, November 20th performed better than the other
sowing dates showing the highest grain yield (4.81 t ha-1). Gradual
decrease of growth parameters, yield attributes and yield were observed when
wheat seeds were planted in delay after November 20th. Based
on the above findings it may be concluded that wheat seeds of BARI Gom 24 may be
sown on 20th November
for obtaining maximum grain yield.
