Effect of root-knot nematodes (meloidogyne spp) on yield of three tomato varieties in zalingei area.

This study conducted at the demonstration farm of the Faculty of Agriculture University of Zalingei during the period from April to August 2013, to evaluate the effect of Root knot nematodes on the yield of three tomatoes (Lycopersiconesculentum) varieties (Castle rock, Strain-B and Rio Grande). Six treatments were randomly arranged in a Completely Randomized Design (CRD) with four replicates. Primary survey carried out to determine the infection of Root knot nematodes on tomato fields in the area and sampling. Parameters measured included: number of leaves per plant, plant height and rating index of root galls. Data collected subjected to statistical analysis. The results showed that: Root knot nematodes found in all tomato fields surveyed in the area (10 fields). The number of leaves on treated Rio Grande variety were significantly lower compared with the number of leaves of untreated plants at (P= 0.05). The plants from the different varieties grown in treated soil showed longer plants than untreated one, throughout the six observations. The variety Strain-B was the most susceptible to the root knot nematodes among with the other two varieties.
