Growth and yield of grafted watermelon in Meloidogyne incognita (Tylenchida: Heteroderidae)-infested soil: Biocontrol of plant parasitic nematodes in vegetables
The objective of this study was to evaluate the growth, yield and tolerance of grafted watermelon against parasitic Meloidogyne incognita. Watermelon was grafted on rootstocks of Lagenaria siceraria, Cucurbita moschata, Cucumis melo and Cucumis sativus. Agronomic variables, yield, and tolerance to n...

| Summary: | The objective of this study was to evaluate the growth, yield and tolerance of grafted watermelon against parasitic Meloidogyne incognita. Watermelon was grafted on rootstocks of Lagenaria siceraria, Cucurbita moschata, Cucumis melo and Cucumis sativus. Agronomic variables, yield, and tolerance to nematodes were evaluated. The grafted plants flowered eight days earlier and presented higher growth, yield (18.5 t ha-1) and fruit size up to 18 % compared to the control. The watermelon grafted on the rootstocks of L. siceraria and C. moschata obtained the lowest galling index (11 and 25 % respectively), number of eggs per g of root (544 and 753 respectively) and number of females per g of root (12 and 22 respectively) compared to the control. The study showed that growth, flowering and yield of grafted plants were significantly influenced by the rootstocks despite the presence of nematodes. |
