One of the difficulties in the management of the soybean cyst nematode (SCN), Heterodera glycines, is the prediction of damages depending on a previously determined population of the nematode in the soil. Studies carried out in Brazil have shown that the critical population level is between 1 and 5 cysts/100 cm3 of soil. However, many soybean producers are obtaining good yields in fields with populations in those levels and or higher. The objective of this work was to know the effect of the SCN on soybean yield, in various population levels in field sites in the states of Paraná (PR), São Paulo (SP) and Rio Grande do Sul (RS), Brazil. Five experiments were conducted in 2001/02 and nine in 2002/03, in the following localities: Sertaneja (PR), Florínea (SP), Tarumã (SP), Pejuçara (RS) and Espumoso (RS); Cornélio Procópio (PR), Assis (SP), Cruzália (SP). In 2002/03, in Pejuçara, the area was not infested and, in Tarumã, the population was below one cyst/100 cm3 of soil. The yield of susceptible cultivars (CD 201, CD 202, Embrapa 48, BRS 133, BRS 156, IAS 5, BRS 137, BRS 153 and BRS 154, in Rio Grande do Sul) and resistant cultivars (identified as R1, R2, R3, R4, and BRS 231) was compared. The experimental design was a randomized complete block with 10 treatments and four replicates. The yield and the initial population of cysts and eggs per100 soil cm3 were evaluated. Egg populations varied among localities from 296 to 1662/100 cm3, in 2001/02, and from 563 to 4062/100 cm3, in 2002/03. The average yield of the susceptible group and of the resistant group of cultivars was compared using the F test. In general, the yield of the resistant cultivars was higher than the susceptible cultivars. The results showed that SCN reduced soybean yield from 173 to 710 kg/ha, in 2001/02, and from 154 to 676 kg/ha, in 2002/03. Resistant cultivars contributed significantly to minimize the damages caused by SCN, although the detected population levels of SCN were not high. The results obtained in Tarumã and Pejuçara showed that in areas with absence of SCN susceptible cultivars were as productive as the resistant ones, validating the positive effect of the resistant cultivars in infested areas.
