A fourth treatment (IV) a non-treated check was included. The increase of the initial population of nematodes on common beans at flowering time in first year for treatments I, II, III and IV were: 1.2, 1.5, 5.0 and 14.2 times respectively. In the second year on corn after beans the population increase were: 6.1, 50.5, 64.8 and 91.8 times for treatments I, II, III and IV respectively. The total net profit in cruzeiros per ha for two crops at the market price for different treatments was: 96,326, 89,062, 65,270 and 52,620 for I, II, III and IV respectively (US$ 1 = Cr$ 442.75 in May, 1983).  agreen manures  aAdubação Verde  aCerrado  aFeijão  aHelicotylenchus Dihystera  aMeloidogyne Javanica  aMilho  aPhaseolus Vulgaris  aPratylenchus Brachyurus  aRotação de Cultura  aZea Mays  aBean  aCriconemella ornata  aMaize  aNematoide de planta  aPlant nematodes  aRotational cropping1 aSCOLARI, D.
