The grain production systems at the Brazilian Western Region, mainly in Mato Grosso do Sul State, have some weak points, among them the lack of alternative crops for the fall-winter season. With the purpose of studying the behavior of sorghum and sunflower genotypes, under the no-till cropping system and at the fall-winter season, two experiments were carried out in the year 2000, at Embrapa Western Agriculture, Dourados, Mato Grosso do Sul State, Brazil. The randomized blocks experimental design was used. The sunflower results showed significant differences among the genotypes grain yields. In average, the yield was 2.176kg ha-1. The highest yield was obtained with the M 734 hybrid, which yielded 3.028kg ha-1. The sorghum average grain yield was 7.861 kg ha-1, noting that the BR 304, M 51, and AG 2005E genotypes yielded 9.865, 9.771, and 9.055kg ha-1, respectively.
