RESUMO
In order to list the genera buildup on Brassica oleracea (Cauliflower), Capsicum frustscens (Chillies), Spinacia oleracea (Spinach) and Phaseolus vulgaris (Farash bean) a general survey was carried in the summer season of 2013. On examining the soil samples as well as root samples of Cauliflower Boleodorus, Psilenchus, Helicotylenchus, Merlinius, Aglenchus and Filenchus were encountered with their absolute density of 18, 31, 34.5, 35, 35 and 31.5 %. On Chillies, Tylenchus, Helicotylenchus, Psilenchus, Pratylenchus and Hirschmaniella with their absolute frequency of 86, 96.6, 100, 100 and 96.6 % respectively were collected. Among these five genera recorded on Chillies the Relative prominence value of 16 % is lowest for Psilenchus and 26.7 % for Helicotylenchus. Merlinius, Psilenchus, Aglenchus, and Boleodorus were encountered on examining the soil and root samples of Spinach during the period of study. Boleodorus was met with the highest percentage of frequency of 90 % as well as highest proportion of absolute density of 37 % and lowest value of 24 % in case of Merlinius and Psilenchus. Soil samples as well as root samples of Farash bean, Aglenchus, Tylenchus, Hirschmaniella, Helicotylenchus and Psilenchus were encountered with their absolute density of 27, 19.5, 33, 33 and 35.4 %. The absolute frequency of 100 % was found in Tylenchus with the lowest frequency of 70 % in Helicotylenchus. Among the genera recorded on Farash bean relative prominence value happened to be highest in Hirschmaniella with the value as 23.6 % and lowest on Tylenchus with the value of 14.2 %.
