Abstract

Exotic and invasive species have threatened the integrity of many ecosystems in the world. They not only harm the native species diversity but also disturb the biological integrity and functioning of an ecosystem. Although these species cause huge economic and social impacts in most of its non-native ranges, one of the most significant impact includes its allelopathic effect on native vegetationand crop species. In India, several invasive and exotic species have been reported some of which are Parthenium hysterophorous, Lantana camara, Crotalaria pallida, Eucalyptus globulus, Acacia auriculiformis. These species are native to tropical America or Australia and are known to proliferate in varied landscapes causing harm to a lot of forest and agricultural regions, replacing the native vegetation and crops. This study aims to understand the allelopathic effects of leaf litter of these invasive and exotic species on the germination and seedling traits of Pisum sativum (common pea plant), a widely grown crop species in India. Using a randomized complete block design, this study estimated the effects of lead litter type and amount on the productivity and root traits of pea plants It was observed that both leaf litter type and amount significantly affected the productivity and seedling traits in pea and among all the species, the lead litter of Parthenium hysterphorous proved to be the most detrimental to the germination and seedling traits of pea seedlings.
