| dc.description.abstract | The present study was conducted to determine nematode prevalence in tomato plants in two monoculture tunnel farms in Dahachowk. A total of 40 soil samples were collected from November-January at the time of harvest and subjected to Baermann set up for nematode isolation and extraction. The study reported occurrence of both parasitic and free living nematodes. 9 nematode genera belonging to 3 orders were identified. Among them 56% were parasitic and 44% were free living.Among parasitic nematodes, 22.9% Meloidogyne juvenile, 20.84% Tylenchorhynchus, 12.99% Helicotylenchus, 11.88% Hoplolaimus and 0.5% Discocriconemellawere encountered while among free living, 27.19% Rhabditis, 1.91% Dorylaimus, 1.4% Eudorylaimus and 0.35%Filenchus werereported. In general, Meloidogyne juvenileandRhabditis was the most frequent parasitic and free living genus with 22.96% and 27.19% composition while DiscocriconemellaandFilenchus were the least frequent parasitic and free living genus with 0.5% and 0.3% composition in both tunnels.Also soil samples from both tunnels were found to be acidic with average pH of 4.6 and 4.1 while average moisture measured were 93.22% and 77.42% for both tunnels. No significant differences (p>0.05) were observed in nematode distribution from both tunnels in relation to depth, pH and moisture contents. However, findings suggested mixed nematode diversity that tunnel 2 to having more nematode prevalence than tunnel 1 showing phyto-pathogenic tendencies for hybrid mono-culture practice. Therefore, regular researches on particular criterion can unfold hidden secrets on nematode prevalence for the region. | en_US |
