Effect of Nitrogen Fertilisation and Inoculation with Bradyrhizobium japonicum on the Fatty Acid Profile of Soybean (Glycine max (L.) Merrill) Seeds

Soybean is a valuable protein and oilseed crop ranked among the most significant of major crops. Field experiments were carried out in 2016–2019 South-East Poland. The influence soybean cultivars (Aldana, Annushka), nitrogen fertilizer (0, 30, 60 kg?ha?1 N) inoculation with B. japonicum (control, HiStick® Soy, Nitragina) on content fatty acids (FA) seeds was investigated three-factorial experiment. This study confirms genetic determinants acid composition their differential accumulation levels for C16:0, C16:1, C18:1n9, C18:2, C18:3, C20:0 as well saturated (SFA), monounsaturated (MUFA), polyunsaturated (PUFA) acids. Increasing rate from 30 to kg ha?1 N did not produce expected changes, suggesting use only “starter” N. Inoculation strain Bradyrhizobium (HiStick® BASF, Littlehampton, UK Nitragina, Institute Soil Science Plant Cultivation–State Research Institute, Pu?awy, Poland) recommended it will cause decrease SFA C16:0 levels. considered nutritionally beneficial its contribution total determines hypercholesterolemic index, third accumulated seeds. interaction formulation demonstrated. An increase value resulted C18:1, C18:3 each decreased by almost one unit every 1% content. dominant effect weather conditions FA profile C18:2n6/C18:3n3 ratio suggests need further evaluation progress respect under varying habitat conditions.
