Resumo: | ABSTRACT The aim with this study was to evaluate the effects of single- and twin-row spatial arrangements associated with different doses of fertilization on soybean yield and its components. The experiment was carried out at Federal University of Goiás, Campus of Jataí, in a split-plot randomized block design with 10 treatments and four replicates. Each plot corresponded to a dose of P and K fertilization (0, 50, 100, 200 and 400% of the recommended dose) and the subplots to two types of spatial arrangements: single and twin rows. The yield components evaluated were plant final population, number of pods and seeds per plant, number of seeds per pod, weight of a thousand grains and yield. The increase in fertilization dose, even at doses two and four times higher than recommendation, results in increased soybean grain yield for both studied arrangements. The single-row arrangement provides greater soybean yield, regardless of the dose of fertilization, although most of the production components were not negatively affected, except the population.
