Allelopathic effects of Amaranthus viridis L. on germination and growth of Eruca sativa L.

A pot experiment was conducted at Alzaiem Alazhari University during 2020/2021 to study the effect of Amaranthus viridis powder incorporated into the soil on germination and growth of garden rocket (Eruca sativa). The experiment was arranged in completely randomized design (CRD) with four replicates. Five concentrations (0, 0.5, 1.0, 1.5 and 2.0% w/w) on basis of Amaranthus viridis powder incorporated in the soil. Results indicated that Amaranthus viridis powder decreased germination, shoot length, leaf area, shoot and root fresh and dry weight as well as chlorophyll content and some chemical elements (P, Ca, Mg, Fe).
