POPULATION STUDIES OF PHYTONEMATODES AND EFFECT OF COWDUNG ON THE PLANT GROWTH
Datrika Swapna*, Geeta Rajalingam and P. Nagaraja Rao
ABSTRACT
The phytonematode diversity changes were studied by mixing the cow dung into the all soil samples collected and checked for the population of nematodes. After the application of Cow dung into the soil, the growth of the phytonematodes were decreased when compared to the test crops grown soil. Based on the phylogenetic studies it was identified that species Psilenchus dunensis, Tylenchorhynchus brevilineatus, more related than the other species Belonolaimus longicaudatus, Hoplolaimus indicus, Peltamigratus indicus and Aorolaimus perscitus. Thus, our present studies revealed that there is a diversity changes of phytonematode based on type of the plant. This diversity is more at root level as it is effecting the soil physicochemical nature of the root zone. Hence, based on these results, one can develop phytonematode control methods.
Keywords: Diversity, phytonematode, Psilenchus dunensis, Tylenchorhynchus brevilineatus.
