In two field experiments on sandy soils in Florida, densities of Meloidogyne incognita race 1 were lowest (P 0.05) following the cowpea (Vigna unguiculata) cultivars Tennessee Brown, Mississippi Silver, and California Blackeye #5. Final densities of M. incognita in soil were high ( 650/100 cm soil) following the cultivars Whippoorwill, Pinkeye Purplehull, and Texas Purplehull. Population densities following the cultivar Purple Knuckle were intermediate. No consistent differences among cultivars were observed for population densities of other plant-parasitic nematodes. Mississippi Silver was the highest yielding cultivar in both experiments.
