Physico-Chemical And Biological Components Of Rhizosphere Soil And Relevance To Phytonematode Prevalence Their Control On Spicy Crops

Abstract

It is a changing and complex habitat that occurs around the roots of plants and other organisms over time and space. All plant-parasitic nematodes must pass through the rhizosphere to reach their host, but the length of time they stay depends on their parasitic behaviour. As the soil around the roots compacts, the rhizosphere develops its own set of biochemical, physical, and biotic characteristics distinct from the bulk soil. As cells die in the epidermal and cortical layers, soluble exudates are discharged further down the root, and complex carbon-rich compounds are released. Plant parasites and nematodes that feed on bacteria are more abundant in the rhizosphere than in the surrounding soil. Rhizobia, mycorrhizas, and plant pathogens have contributed significantly to our understanding of the interactions of microorganisms and nematodes in the rhizosphere, and they continue to do so. Thyrotrophic interactions in the rhizosphere have been demonstrated in a number of studies, including this one, in which nematodes and bacteria cooperate or compete to affect the plant's host. The goal of this study is to look into the prevalence and control by using cow dung against phytonematode infestations in spicy crops in relation to known physicochemical and biological rhizosphere soil components.
