The effect of Meloidogyne incognita population on infested seedlings were studied in the screen house in 2006, sets of four and six week old seedlings of four pepper cultivars (Gombe-local, katsina-local, Kano-local and Iddo-local) were inoculated with either 0 (uninfested), 5,000, 10,000, or 20,000 eggs of M.incognita Race 2. Sensitivity to the nematode invasion was pronounced in Gombe-local and Katsina-local as compared with Kano-local and Iddo-local. Regardless of the variety, four and five weeks infested seedlings showed high level of susceptibility to M.incognita than six weeks old infested seedlings, which suppressed the virulence of the nematodes with corresponding significant increase in plant biomass. Seedlings age and inoculums density interactions effected high susceptibility in infested younger plants as opposed to similar interactive in effect to six-week old seedlings, which exhibited high level of tolerance to the nematode
