ABSTRACT
The root knot nematode Meloidogyne incognita cause serious damage in the crop fields in many countries. Cucumber (Cucumis sativa) is one of the crops that are badly affected by the root knot nematode (Meloidogyne incognita). The present studies were conducted to assess the damaging effect of root-knot nematode on different parameters of
Cucumber by relating infectious plants with non-infectious plants at different inoculums levels. The data was recorded after five weeks of plant germination from inoculated and non-inoculated plants pots. At a level of 500 J2s reduction in growth parameters was 7.833, 28.133, 11.1666, 2.166, 3.6, 1.3 while at the inoculum level of 2000 J2s reduction in growth parameters was 5.333, 17.833, 8.1666, 1.433, 2.4333, 0.9666. Results revealed that affect of M. incognita on growth parameters correlate directly with inoculums levels. However, inverse relationship was found between reproduction factor and inoculum levels. With the increase in inoculums level, the growth parameters were decreased, however, the nematodes population was increased.
