Abstract
Lycopersicon esculentum is a widely grown vegetable crops throughout the world and it is highly affected by root-knot nematode (Meloidogyne spp.); globally more than 27% yield losses in tomato is due to their infections. As the inoculums level increases, the absorption, translocation and photosynthesis rate decreases in the host plants; it means damage caused by nematodes is directly proportional to the number of second-stage juveniles (J2) which are penetrating and establishing in the host roots. In this aspect, the present study focused on the effect of different inoculums on the tomato plants. The study reports that with increased intensity of root-knot nematode infection, the plant growth and biomass were highly reduced. Key words: Tomato, root-knot nematode, inoculum, growth, infection.

Summary
Tomato (Lycopersicon esculentum) is a widely grown vegetable crops throughout the world and root-knot nematode (Meloidogyne spp.) is the major pest in this crop. More than 27% yield losses in tomato is caused by root-knot nematode (Kaur et al, 2011). In this respect, the present study was focused on the effect of different inoculum levels of M. incognita on the plant growth and nematode infections in tomato plants
