Resumo: | Broadcast sowing soybeans at seed rates of 57, 110 and 154 kg/ha was tested at Ribeirão Preto Experimental Station, Instituto Agronômico, São Paulo State, Brazil, in 1978-1979. The experimental area received previous fertilization of 160 kg/ha of P2O5 as simple superphosphate and 90 kg/ha of K2O as potassium chloride, and a mixture of the herbicides "trifluoraline" (2 l/ha) and "metribuzin" (0.7 kg/ha). Seeds of cultivar Paraná were distributed on the soil sulface and immediately incorporated into soil by disk harrow. Plant height at maturity and insertion height of lower pods were positively related with seeding rate. Seed yields of 2682 and 2675 kg/ha for the rates of 110 and 154 kg/ha of planted seeds did not significantly outyielded the seeding rat of 57 kg/ha.
