Abstract

Effects of Root Knot Nematode population at different density levels on olives were also tested. Infection signs and indicators were increased as inoculation level increases. Inoculation level at 3000 egg.pot-1 resulted in the highest number of galls(42.66 .2g.root-1), females (44.33 .2 g. root-1), egg masses (42 .2 g. root-1), mobile stages (males and juveniles) (43.66 .100g soil-1), population density (57000 individuals), reproduction factor (19.00%) and root fresh weight(13.47 g). Plant growth and chemical parameters were decreased as inoculation level increases especially at the 3000 egg / pot and resulted in the lowest values of shoot length (26.33 cm), root length (27 cm), shoot fresh weight (11.89 g), leaf area (3.10 cm2), nitrogen level (1.59), protein percentage (10.02%), chlorophyll content of a ,b and total (0.057, 0.028 and 0.085 mg.g-1 fresh weight, respectively).
