SOYBEAN RESPONSE TO FOLIAR AND SOIL FERTILIZATION

Abstract

The objective of this study was to investigate the effect of foliar fertilization as compared to mineral fertilization on yield and yield components of soybean. The experiments were carried out during 2020 and 2021 growing seasons at Research and Development Station for Agriculture Turda (RDSA Turda), Romania, using randomised complete block design with three replications. The two variants of foliar fertilization contain macro and micro elements, being applied in different phases of soybean growth and development. Among the foliar fertilization options, T₁stood out as the foliar fertilization option that contributed to some extent to the growth of plant height, the number of pods/plant, the number of grains/plant, the weight of grains/plant and yield. The second variant of foliar fertilization (T₂) in most of the analysed cases determined a decrease in the yield elements as well as the yield compared to the control variant.
