Abstract

An experiment on the allelopathic effects of Nerium oleander on germination and growth of Italian ryegrass (Lolium multiflorum Lam) was conducted at the Kahramanmaras Sutcu Imam University, Faculty of Agriculture, Department of Field Crops Laboratory during January 2017. The experiment was laid out in completely randomized 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 oC temperature. 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 studied parameters were significantly affected by oleander flower extract concentrations. Results showed that maximum germination %, seedling length, radicle length, plumule length, seedling fresh and dry weight and highest seed vigor index was recorded in control treatment. While minimum values for all the above mentioned parameters were observed at 40 g L-1 of extract concentration. It indicated that Nerium oleander flower extract suppress growth of Italian ryegrass and thus can be used for the control of Italian ryegrass in the crops. However, all other factors need to be studied for sustainability.
