EXPLORING THE ALLELOPATHIC EFFECT OF CINNAMOMUM VERUMON EMERGENCE AND SEEDLING GROWTH OF WILD PEA (Pisumsativum subsp. elatius).

It is important to identify plant species that have herbicidal potential so that their bio-extracts can be used as a safer and more effectual novel weed management factor. Therefore, proposed research was planned in Weed Science Laboratory at Department of Agronomy, University of Agriculture Faisalabad during Winter 2018 to check out the allelopathic effects of Cinnamomumverum (Dalchini) on weed Wild Pea (Pisumsativum subsp. elatius) and determination and quantification Phenolic compound present in aqueous extract of bark of C. verum. The experiment was arranged under completely randomized design (CRD) having 3 replications. The aqueous extract of C. verum was utilized on wild pea seeds at separate concentrations (2.5%, 5%, 10%, 20%, 40% and 80%). Data with regard to seed germination and seedling growth (shoot length, root length, shoot fresh weight, root dry weigh) of weed was noted following standard procedures. C. verum extract at greater concentration act as bioherbicide and cause inhibitory effects on Pisumsativum subsp. elatius. And at low concentration it showed hermetic effect and enhanced the emergence and seedling growth. Among different Phenolic compound (Syringic acid, pcrumeic, Ferulic acid, Quercetion and Gallic acid) determine in aqueous extract of barck of C. verum. Maximum Quercetion (12.3 %) and minimum Syringic acid (0.60%) was found. Therefore, it was summarized from this study that aqueous extract of C. verummay be used as bioherbicide for biocontrol of weed at higher concentration (80 %) while at lower concentration (10%) as growth promoter.
