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.
