Abstract
An experiment on the perfbrrnance of herbicide (Ronstar. Sencor and I.intur)
on weed suppression towards growth and yield of wheat was conducted at the
Agronomy Field, Shcr-e-Bangla Agricultural University, Dhaka-1207 during
the period from November. 2007 to March. 2008. The experiment was laid out
in a randomized complete block design having twelve combination treatments
viz. (1) Ronstar 25EC Ø 1.0 I/ha. (ii) Ronstar 25 EC @ 1.5 I/ha. (iii) Ronstar
25EC @ 2.0 I/ha. (iv) Ronstar 25flC @ 2.5 I/ha. (v) Lintur 70W6 'd 0.20
kg /ha, (vi) l.intur 70WC1 0.25 kg /ha. (vii) l,intur 70WG @ 0.30 kg /ha,
(viii) Lintur 70WG @ 0.35 kg Tha. (ix) Sencor 70WG 1; 0.30 kg/ha. (x)

(xi) Sencor 70W0 47 0.50 kg /ha. and
(xii) Sencor 70WG ( 0.60 kg /ha, along with control (weedy) with three
replications. Result showed that higher dry wcightiplant. 1000 seed weight,
total grain yield, harvest index and benefit cost ratio (42.58g. 45.84g. 3.51 t!ha.
46.69% and 1.50 respectively) were obtained with Sencor 70WC1 (i. 0.50
Kg/ha treated crop. The highest plant height, number of tillers/plant. number
of spikes/plant. spike length at harvest was also observed with the same
treatment. In addition to those parameters. the lowest weed dry matter (19.38
kg/ha.) by Sencor 70WG d! 0.60 kg/ha. Sencor 70W6 (21? 0.50 kg/ha,
showed the highest net return (23500.00 fl/ha). So. Sencor 70WG (2 0.500.60
kg/ha, could he considered as the recommended rate for controlling
weeds in wheat field.
