| 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... |
