摘要：An experiment was conducted at Agronomy Field Laboratory of Rajshahi University to evaluate the effect of variety and weeding regime on yield and yield components of wheat. Four varieties viz. Prodip -V 1 , Gourab -V 2 , Shatabdi -V 3 , Bijoy -V 4 and five weeding regime viz. a) No weeding -W 0 , b) Weed free -W 1 , c) One hand weeding at 20 DAS -W 2 , d) Two hand weeding (1st at 20 DAS and 2nd at 42 DAS) -W 3 and e) Lintur 70 WG @ 250 g ha -1 -W 4 were included as treatments in the experiment. The experiment was laid out in a Split-plot Design with three replications. The results revealed that Prodip produced the highest grain yield (5.33 t ha -1 ) followed by Gourab (4.85 t ha -1 ), while the lowest grain yield (3.98 t ha -1 ) was obtained from Shatabdi. The highest grain yield (5.09 t ha -1 ) was obtained in Weed free (W 1 ) followed by W 3 (Two hand weeding) (4.89 t ha -1 ) and the lowest grain yield (4.13 t ha -1 ) was obtained in no weeding treatment (W 0 ). The highest grain yield (5.64 t ha -1 ) was obtained from the combination of Prodip and weed free treatment (V 1 W 1 ) and the lowest (3.57 t ha -1 ) was obtained from the combination between Shatabdi and no weeding treatment (V 4 W 0 ).
