A field experiment was conducted during Rabi season of 2014 to study the effect of herbicides on weed control efficiency and yield attributes in Brinjal. The experiment consisting of 10 treatments comprising 4 herbicides (alachlor at 1.0 and 1.5 kg a.i. /ha, butachlor at 1.0 and 1.5 kg a.i. /ha, pendimethalin at 1.0 and 1.5 kg a.i. /ha, pretilachlor at 1.0 and 1.5 kg a.i. /ha) compared with weed free check, unweeded control. Results revealed that the application of butachlor and pretilachlor at 1.5 kg a.i. /ha were found to be phytotoxic while pendimethalin at 1.0 and 1.5 kg a.i. /ha was found not phytotoxic to the brinjal. The total number and total dry weight of weeds were found to be maximum in unweeded control and weed control treatments decreased these parameters but pendimethalin at 1.5 kg a.i. /ha were the lowest. WCE (%) was highest with the pendimethalin at 1.5 kg a.i. /ha. The yield parameters viz., number of fruits, fruit weight, and fruit yield decreased significantly in unweeded control while weed index was higher. The fruit yield was significantly higher with application of pendimethalin at 1.5 kg a.i. /ha.
