We studied the phytotoxic effect of three pre-emergence herbicidal treatments such as butachlor, alachlor, oxyflurofen along with weedy check control and weed free check (hand weeded) treatments having three replication under Randomize Block Design (RBD) to evaluate yield and yield attributes characters and oil content in groundnut (Arachishypogaea L.). It is fact that application of herbicides can check the weeds timely and effectively but also believed that application of herbicides can alternate the ecology of leguminous crop. This alternation in ecology may directly impair on yield and yield attributes characters and oil content of groundnut. Based on our study it was found that all the herbicidal treatments as well as weed free check significantly increased the yield and yield attributing characters and oil content of groundnut as compared to weedy check control. Among the all treatments, weed free treatment showed best results and recorded highest yield (13.92 q/ha) followed by butachlor (13.17 q/ha) which increased to a tune of 26.54% and 19.72% respectively over weedy check control. Besides this harvesting oil and oil percentage content was noted highest in weed free check (6.86q/ha and 49.33%) followed by butachlor (6.16 q/ha and 46.78 %). Retrieval the fact, it is resolved that beside weed free treatment, application of pre emergence herbicides with two hand weeding at 21 DAS and 40 DAS can increases the yield and oil content of groundnut crop significantly over the weedy check control.
