Community Analysis of Plant Parasitic Nematodes in and Around Bilara, Rajasthan

Abstract

During the survey of Bilara area some interesting findings were noted. In some area pearl millet and vegetable crop are in very flourishing conditions. The survey was conducted to the nematodes community structure soil and root sample, representing 15 locations were examined. Eight important genera of plant-parasitic nematodes namely Meloidogyne incognita, Tylenchorhynchus mashhoodi, Hoplolaimus indicus, Helicotylenchus indius, Xiphenema sp., Longidorus sp., Paralongidorus sp. and Paratrichodorus porosus were found (Kamra A, Pankaj, Sharma H K and Mishra S D 2001). 13 agriculture field surveyed where mustard (Brassica campestris), jawar (Sorghum vulgare), peart-millet (Pennisetum tyhoides), wheat (Triticumae aestivum), castor (Ricinus commiinii), caner (Nerium indicum), tulsi (Ocimum scanctum), pumpkin (Cucurbitta moschata), spinach (Spincea oleracca), lemon (Citrus limon), brinjal (Solanum melongena) and aak (Calotropis procera). The relative density and elative prominence value of Tylenchorhynchus mashhoodi was (56.41) and (61.24) followed by Helicotylenchus indius (26.11) and (26.09). Tylenchohrynchus mashhoodi most dominant in study area in which nematodes population very highest in Brinjal per 200 cm3 soil. The relative densities of Hoplolaimus sp., Meloidogyne incognita were (6.91) and (3.34) relative prominence values were (5.89) and (2.66). Respectively soil samples were collected from crop fields in order to study the community analysis of plant parasitic nematodes community (Shivakumar M, Poornima K, Mani M P and Umamaheshwari 2002).
