The purpose of this study was tu determine the effects of seed treatment with thiram (2.1 g a.i./kg of seed), streptomycin (1,0 g a.i./kg of seed) and their mixture, on emergence of soybean seed planted in soil with low water availability. Three experiments were carried out on ?Latossolo Roxo Distrófico?, at Londrina, Paraná, in 1977/78, 1978/79 and 1979/80. lhe sou was previously dried by conventional tiliage, before planting. lhe seed were planted in four blocks: the first was irrigated at the planting date, and the other ones sucessively at a four day interval. Each irrigation was equivalent to 10 mm of rainfali. Treatment with thiram always reduced in better emergence during the three years of study. Nevertheless, when the seed remained in the dry soil waiting for irrigation,there was a reduction on emergence, specially for the non-treated seed. Seed treatment with streptomycin had the lowest values of emergence, not differing from the non-treated control in the three years of study. When high quality seed is planted in dry sou, fungicide treatment may protect the seed for periods up to twelve days, depending on the vigor level of the seed lot.
