Abstract

The Relationship Between Soil And Root Nematode Populations As Well As Root Galls Induced By Meloidogyne Incognita (Kofoid And White, 1919) Chitwood, 1949 And Growth Of Abelmoschus Spp. Was Investigated In The Field In 1999 And 2000 Root-Knot Nematode Susceptible Celoasis Argentea L. CV. TLV 13 Was Grown For Twelve Weeks And The Infected Roots Subsequently Ploughed Into The Soil To Serve As Primary Source Of Inoculum. Nematode Induced Galls, Soil And Root Nematode Populations Correlated Negatively With Shoot But Positively With Root Weights. Correlation With Plant Height Was Also Negative. Positive Correlation Was Observed Between Fruit Weight And Number As Well As Height With Fresh Shoot Weight. Plant Height Was Positively Correlated (P = 0.05) With Fresh Shoot And Root Weights. Key Words: Correlation, Meloidogvne Induced Galls, Abelmoschus Species.
