Two greenhouse trials were conducted to determine the influence of ground seed of castor (Ricinus communis), crotalaria (Crotalaria spectabilis), hairy indigo (Indigofera hirsuta), and wheat (Triticum aestivum) on tomato (Lycopersicon esculentum) growth and egg mass production of Meloidogyne javanica (test 1) or M. incognita (test 2). Ground seed from each plant species was individually mixed with an air-dried, fine sandy soil at rates of 0, 0.5, 1.0, and 2.0% (w/w). The mixtures were placed in one-liter plastic pots, and water was added to bring soil to field capacity. After ten days, 0 or 10 000 M. javanica or M. incognita eggs and juveniles were added to each pot. A single 'Homestead tomato seedling was transplanted into each pot and allowed to grow for 70 days in test 1 and 75 days in test 2. Compared to the nonamended control, egg mass production was significantly reduced by all treatments except the 0.5% levels of wheat and castor and the 1.0% castor treatment. The 2.0% levels
