Invasive and Weedy Plant Species in Agricultural Ecosystems

Abstract

Invasive and weedy plant species pose significant challenges to agricultural ecosystems by competing with crops for resources such as nutrients, water, and light. Northern India, with its extensive agricultural landscapes and diverse climatic conditions, provides suitable environments for the spread of various invasive and weedy plant species. This narrative review presents an overview of commonly reported invasive and weedy plants affecting agricultural ecosystems of Northern India based on existing literature.

The review discusses major invasive species, their growth characteristics, and their impact on crop productivity and agricultural biodiversity. It highlights patterns of weed distribution across cultivated fields, roadsides, and irrigation channels. The study is based on previously published research articles, review papers, and institutional reports related to weed ecology and invasive plant species.

This review emphasizes the need for proper documentation, awareness, and sustainable management of invasive and weedy plants in agricultural landscapes. The paper aims to provide a clear and structured understanding for students and early researchers in Botany, Ecology, and Agricultural Sciences.
