The present investigation was conducted to evaluate the effect of weed management practices on weeds as well as crop growth and yield parameters of brinjal along with the economics of weed management during winter season of 2009_10 at the Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur. It was observed that the weed Parthenium hysterophorus dominated the experimental field. All the weed management treatments significantly reduced the dry matter of weeds and increased fruit yield of the crop significantly over unweeded check. Among the treatments, pendimethalin (Extra) (0.64 kg/ha) pre-transplanting + one hand weeding at 40 DAT + pendimethalin (Extra) (0.64 kg/ha) at 45 DAT as postemergence resulted in better performance followed by pendimethalin (1.0 kg/ha) pre-transplanting + one hand weeding at 45 DAT with respect to growth and yield parameters due to effective weed management in brinjal. Maximum benefit: cost ratio was also obtained with pendimethalin (extra) (0.64 kg/ha) pretransplanting + one hand weeding at 40 DAT + pendimethalin (Extra) (0.64 kg/ha) at 45 DAT.
