Studies on the diversity and correlation of soil nematodes with the physicochemical parameters of sugarcane fields from paithan taluka of Aurangabad district (M.S.) India

Plant parasitic nematodes are one of the most important non-visible pests. The aim of this study was to know the soil nematodes, and the effect of soil parameters on the nematode diversity of the sugarcane fields, from Paithan Taluka, Aurangabad district, Maharashtra. The diversity of nematodes was correlated with the soil factors such as temperature, moisture, pH, water holding capacity and electrical conductivity of the soil. After correlating the soil factors with the nematode's diversity, we found that, while some soil factors showed a positive effect, the others showed a negative effect on the nematode's diversity. Seven genera of nematodes were collected & identified from sugarcane soils.,-belonging to the genus Dorylaimus, Dorylaimoides, Iotonchus, Xiphinema, Eudorylaimus, Hoplolaimus, and Indodorylaimus. During this study, Dorylaimus acquired the highest and the lowest position, in February and October respectively.
