The suppressive effect of olive pomace and chicken manure, alone and in combination, was studied in a field infested by Meloidogyne incognita on tomato ( Lycopersicon esculentum Mill.), and cantaloupe ( Cucumis melo L.) in Southern Italy for two crop cycles. Single application of the two amendments suppressed nematode populations in both years, but more consistently in the second year. Crop yields were also increased in amended plots. The combination of olive pomace with chicken manure enhanced suppressiveness and increased crop yield compared to the single amendments alone.
