Quick emergence of Cyperus create competition in the crop production which reduces the crop yield. Nowadays, the more importance is given to sustainable agriculture. Application of allelochemicals can control the Cyperus sustainably. With this notion, field experiment was conducted at The Indian Agriculture College, Radhapuram during summer 2023 to evaluate utilization of Parthenium leaf extract (PLE) for the effective management of Purple nutsedge (Cyperus rotundus). The experiment was laid out in completely randomized block design (CRD) having three replications and seven treatments viz., PLE @ 10%, 11%, 12%, 13%, PLE @ 10% + Glyphosate @ 1.5%, Glyphosate @ 1.5% alone and Control. Application of PLE @ 11% on 3, 10 and 20 DAP, significantly reduces the Cyperus rotundus germination percentage, dry weight, Vigour Index, total Cyperus length, tuber weight, moisture content, chlorophyll content and also improved the Cyperus control efficiency due to the presence of allelochemicals.
