Initial Population Density its Effect on the Pathogenic Potential and Population Growth of Rotylenchulus reniformis on Cowpea (Vigna unguiculata L.)

A glasshouse experiment was conducted to assess the potential of Rotylenchulus reniformis population of Delhi on cowpea (Vigna unguiculata) cultivar Pusa komal. In the present study, different inoculums levels viz., 10, 100, 1000 and 10000 with immature females and equal number of males were inoculated in the rhizosphere of ten day old cowpea plants. Significant reduction in growth parameters were recorded at 1,000 and 10,000 females/ plants.
