This experimental study determined the extent of effects of four population densities of root-knot nematodes on the growth of one-tomato variety.  Tomato is a solanaceous crop.  It is an excellence source of Vitamin A and C.

Results showed that the different densities of root-knot nematodes affect the growth of the tomato plants variety R61 through growth rate, root weight, galls, number and color of leaves.  The population level 10 and 50 egg mass per kilogram soil of root-knot nematodes inoculum level are levels that would affect the growth of tomato plants.
