Allelopathic Influence of Invasive Plants on Crop Productivity in Jaunpur

Abstract

Through direct competition and biochemical interactions, invasive plant species have a substantial impact on agricultural output. A key factor in the dynamics of plant invasion is allelopathy, which is the production of secondary metabolites that affect the growth of nearby plants. Allelochemicals can prevent seed germination, slow plant growth, and change the characteristics of soil when they are released through root exudation, leaching, or decomposition. The allelopathic impacts of invasive species on crop productivity in the Jaunpur district are examined in this study. The effects on germination, growth characteristics, and yield of rice (Oryza sativa) and wheat (Triticum aestivum) were evaluated by laboratory bioassays and field observations. The results show that under allelopathic effect, germination percentage, root-shoot growth, and biomass significantly fall. Compared to non-invaded areas, the crop yield in invaded fields was much lower. The results emphasize how crucial it is to control invasive species in order to maintain agricultural productivity and suggest ecologically based integrated weed management techniques.
