Abstract

An experiment on the allelopathic effects of Nerium oleander on germination and growth of Italianryegrass (Lolium multiflorum Lam) was conducted at the Kahramanmaras Sutcu Imam University, Faculty ofAgriculture, Department of Field Crops Laboratory during January 2017. The experiment was laid out in completelyrandomized design (CRD) with three replications. Four concentrations of oleander flower extract i.e control, 10,20 & 40 g L-1 were used in this experiment. The experiment was performed in climatic cabinet having 20 oCtemperature. The seeds were kept for 14 days and then different attributes were studied such as germination %,seedling length, radicle length, plumule length, seedling fresh and dry weight and seed vigor index. All the studiedparameters were significantly affected by oleander flower extract concentrations. Results showed that maximumgermination %, seedling length, radicle length, plumule length, seedling fresh and dry weight and highest seedvigor index was recorded in control treatment. While minimum values for all the above mentioned parameters wereobserved at 40 g L-1 of extract concentration. It indicated that Nerium oleander flower extract suppress growth ofItalian ryegrass and thus can be used for the control of Italian ryegrass in the crops. However, all other factors needto be studied for sustainability.
