Abstract
The management of root-knot nematode (Meloidogyne incognita) in carrot was studied over a three-year period in Sl. Vincent. Onion (Al1ium cepa), chive (Allium schaenoprassum), corn (Zea mais) and eddoe (Colocasia esculcnta var. antiquorum) were found effective in reducing root-knot nematode population densities in the soil. Cropping systems were then designed and tested for their effectiveness in reducing nematode population densities and galling damage in carrot (Daucus carata). Cabbage-carrot, chive-carrot and onion-carrot were found to be the most effective. Cabbage-carrot and chive-carrot significantly reduced unmarketable yields and root damage in carrots as compared to carrot monoculture. Root gall index was positively correlated with unmarketable yields. Economic analysis showed that the two intercropping systems were more efficient in the use of land, labour and capital resources than carrot monoculture, and that the overall farm income is greatly increased by intercropping carrot with cabbage or chive.
