100 presoaked seeds of varieties Bragg and Birsa-1 of Soybean (Glycine max L.) were treated with three concentrations namely 0.25%, 0.50% and 1.00% for Lasso and 0.17%, 0.33% and 0.66% for Basalin for two hours and then sown in experimental field in two replications along with the control after thorough washing. Germination percentage showed significant reduction in all treatment doses of both the varieties except low and medium treatments of Bragg, where the reduction was non-significant. For observation on plant height ten randomly selected competitive plants from each replication were considered. Observations were recorded at the end of 6th, 7th and 8th week. Plant height showed reduction in both herbicide treatments at all concentrations in variety Bragg. In variety Birsa-1 also, the height and growth rate were reduced in both herbicide treatments but no definite correlations were observed. Variety Birsa-1 seemed to be more sensitive to the treatments than variety Bragg.
