Impact of soil pollutants on diversity and abundance of earthworms in cauliflower crop

Abstract

The present study was designed to elucidate the effect of soil pollutants on diversity and abundance of earthworms in a winter vegetable crop (cauliflower). Collection was done through November to January and samples were anesthetized in alcohol, preserved in 10% formalin solution. The soil and water analysis was performed by atomic absorption spectrophotometry. The Shannon-Weiner Diversity Index (Hʹ) of sampling site (Chack 204) was 1.803, evenness was 0.302 and dominance was 0.831. A significant difference of abundance was observed (t=12.62, p=0.0066 at p
