Abstract
An experiment was conducted to study the performance of different herbicides on weed suppression in wheat field at the Agronomy Field, Sher-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 of Ronstar 25EC @ 1.0 -2.5 L/ha, Lintur 70WG @ 0.20 -0.35 kg /ha, and Sencor 70WG @ 0.30-0.60 kg/ha, along with control (weedy) with three replications. Results showed that higher dry weight/plant (42.58g), 1000-seed weight (45.84g), total grain yield (3.51 t/ha), harvest index (46.69%) and benefit cost ratio (1.50) were obtained with Sencor 70WG @ 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. The lowest weed dry matter (19.38 kg/ha) and the highest net return (23500.00 Tk/ha) was also shown by Sencor 70WG @ 0.60 kg/ha.
