Effect of weed management practices on crop growth and yield of winter season brinjal (Solanum melongena L.) under chhattisgarh plains

A field experiment was conducted to evaluate the effect of weed management practices on weeds and fruit yield of brinjal during winter season of 2009–10 at Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Parthenium hysterophorus was the major weed in the experimental field. Application of pendimethalin (extra) (0.64 kg/ha) pre-transplanting + one hand weeding at 40 DAT + pendimethalin (extra) (0.64 kg/ha) at 45 DAT as post-emergence effectively controlled the weeds and increased the fruit yield of brinjal followed by Pendimethalin (1.0 kg/ha) pre-transplanting + one hand weeding at 45 DAT. The maximum net return (Rs. 157386/ha) as well as benefit: cost ratio (3.57) was also obtained with pendimethalin (extra) (0.64 kg/ha) pre-transplanting + one hand weeding at 40 DAT + pendimethalin (extra) (0.64 kg/ha) at 45 DAT.
