Two-year pot experiments were carried out to study the effect of increasing magnesium fertilization (0-1.0 g Mg/pot) and spraying with Gibberellin (GA3) on yield and chemical composition of soybean. Studies showed statistically significant increase of bean yield after spraying (GA3). As a result, number of pods and each plant increased by 11, their weight and number of beans in a pod increased by 15. Moreover, stems lengthened by 27 while their weight increased by 11. No significant effect was observed of magnesium fertilization upon soybean yield. Gibberellin increased N, P and K content in the beans, K and Ca content in the leaves, and P and K content in the stems. Fertilization with magnesium increased N content, especially in the beans, pods and stems
