Effect of chemical weed management on growth and yield of kharif sorghum was studied in sandy soil in the experimental farm of Lovely Professional University, Phagwara during 2017. The experiment was laid out in Randomized Complete Block Design with seven treatments and three replications. Among the all treatments one is control, one treatment comprises of pre- emergence herbicide only (Pendimethalin), one treatment comprises of post-emergence herbicides only with the combination of Atrazine and Tembotrione, the rest four treatments comprise of herbicides (both pre and post-emergence) combination of 2,4-D, Atrazine, Pendimathalin, Tembotrione in different doses. The treatment in which Pendimethalin @ 1L a.i. per ha (PRE) fb 2,4-D @ 0.87 L a.i. per ha (POST) + Atrazine @ 0.63 kg per ha (POST) were used, showed the significant impact on the growth and yield attributes of sorghum. The plants of this treatment showed significantly higher plant height, leaf area index, panicle length and grain yield as compared to the other treatments of the experiment.
