Abstract

The experiment was conducted to find out the varietal performance on different yield contributing parameters and yield of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh duting 2014-15. The experiment comprised four improved wheat varieties viz. (i) BARI Gom-21 (Shatabdi), (ii) BARI Gom-25, (iii) BARI Gom-26 and (iv) BARI Gom-27. The experiment was laid out in RCBD design with three replications. Data was taken on different yield contributing parameters such as spike length (cm), number of spikelet’s spike-1, number of grain spike-1, thousand grain weight (g), grain yield (tha-1), straw yield (tha-1), biological yield (tha-1) and harvest index (%). Experimental results indicated that the highest grain yield was obtained with BARI Gom-26 (2.636 t ha-1). The maximum values in spike length (15.89 cm), spikelet’s spike-1 (18.63), grain spike-1 (55.89) and 1000 grain weight (42.48 g) was found with BARI Gom-21 (Shatabdi).
