ABSTRACT
Three
(3) tomato varieties: UTC Jos, Abakaliki Local and Tiv Local were evaluated for
susceptibility/resistance against root-knot nematode disease in Abakaliki sandy
clay loam soil. The study was carried out in randomized complete block design
(RCBA) with four (4) replications. Results showed that UTC Jos was most
susceptible to the disease as highest number of galls was recorded on it. Next
in susceptibility to the disease was Tiv Local. The tomato variety Abakaliki
Local was least affected by the nematode. Reduction in tomato fruit yield was
highest on UTC Jos which was most affected by the nematode. The same was true
for chlorotic and wilting symptoms associated with the disease.
