Abstract:

Trees, especially fast-growing multipurpose species, are becoming an integral part of intensive commercial agroforestry models introduced in recent times. Yet, the major hindrance for their productivity and survival is weed infestation with its toxic effects. They eventually decline the biodiversity by smothering native plants and disturbing their ecological niche. Parthenium hysterophorus invasion is a worldwide threat and acts as a potential menace in the biological phenomenons of germination and growth, effecting plant biodiversity. Our study aimed to examine the outcome of aqueous leaf extract (ALE) and leaf oil (LO) of three exotic Eucalyptus species (E. citriodora, E. tereticornis, and E. camaldulensis) on germination and growth performance of Parthenium hysterophorus using two experiments. In the first experiment, we compared the inhibitory effect of aqueous leaf extract and leaf oil on seed germination of weed, while in the second experiment, we studied the different concentrations of aqueous leaf extract and leaf oil of promising Eucalyptus species from the first experiment on Parthenium hysterophorus. We measured the growth characteristics such as Germination percent, Speed of germination, Root length, Shoot length, Total seedling length, Seed vigor, and Phytotoxicity percent. The study highlights species E. citriodora found to be more promising for weed control and subsequently selected using different concentrations for the second experiment. Bioassay of E. citriodora oil at 5 ppm concentration was found to be more effective for weed suppression than aqueous extract concentrations. The study suggests an eco-friendly method to suppress the weed population and effective management in weed control.
