 In: Nematologica v. 26, no. 2, p. 220-22981-636634Summary: Yield of spring barley was reduced by increasing nematode population density in a field trial with cv. Sabarlis on Meloidogyne naasi infested land. A series of significant linear regression coefficients relating nematode population density, host symptoms and barley growth and yield was obtained. Grain yield was reduced by 3.5 per cent for every 10 juveniles/g soil reaching 50 per cent loss at 150 juveniles/g soil. Fertile ear production was the major but not sole yield component affected. The field trial indicated an equilibrium density of approximately 40 juveniles/g soil for the nematode. A glasshouse experimental confirmed the field trial
