This study was conducted to evaluate some effects
of hazelnut dried husk extract and husk compost on nematode infection and some
plant parameters of tomato inoculated by mixed root-knot nematodes populations
of Meloidogyne hapla and M. arenaria in pot experiment. The dried
hazelnut husk obtained from after harvest were used. For both husk extract and
husk compost treatment, 50 grams of hazelnut husk was used. Approximately 1000
second stage juveniles (J2) was inoculated to susceptible tomato cultivar (Solanum lycopersicum cv. Rio Grande). At
the end of 8 weeks, the gall numbers on the root, number of the juveniles in
the pot, plant fresh root weight and total plant fresh weight were measured. As
result, the husk compost treated plants had lower gall on the root system and
juvenile numbers in the pot soil by comparison with husk extract treatment. For
plant growth parameters, the total plant fresh weight was significantly
different for husk compost treatment.
The all results seemed that the husk compost treatment has more effect
on Meloidogyne spp. gall numbers than
husk extract application on tomato.
