Conteúdo: | In a greenhouse test, three treatments involving yard-waste compost amendment (applied to the soil surface, mixed with the soil, or no amendment were evaluated at three inoculum densities of Meloidogyne incognita race 1 (0,025, or 1000 juveniles pot). Plants responses were evaluated on the highly suscetible 'Clemson Spineless' okra (Hibiscus esculentus) during spring of 1994. There was a significant interaction (P< 0,05) between organic amendment placement and inoculum density for egg-mass rating, but not for galls, plant height, or top and root dry weights. Egg-mass rating was not affected by placement of the amendment on the surface or incorporation, but was significantly higher (P< 0,05) at the 1000 inoculum level when no organic amendment was used. Effects of inoculum density were significant(P< 0,05) for plant height, dry weight, and gall rating, and in some cases for shoot and root weights. Regardless of the inoculum concentration, the shortest plant height and lowest weights of shoots and roots were observed when the amendment was mixed with soil. Gall rating was no affected by organic amendment placement, but was affected by inoculum concentration, showing higher levels at the highest nematode density.
