Response of New Yellow Lupin Varieties to Inoculation with Bradyrhizobium sp. Lupinus under Central European Conditions

The aim of a two-factorial field experiment was to determine how the inoculation seeds/soil with preparations Bradyrhizobium sp. Lupinus (Nitragina—seed inoculation, Nitroflora I—seed II—soil HiStick® Lupin—seed inoculation) affected plant development, seed chemical composition and yield two yellow lupin varieties (Bursztyn, Puma). This carried out four replications in 2018 2019 Poland. Precipitation during both vegetation periods similar or lower than long-term mean. Average Puma significantly greater Bursztyn (by 0.22 t ha−1). According correlation coefficients, mainly related height, dry mass nodules per 1000 seeds. Our results suggest that legumes, such as lupin, should always be inoculated Bradyrhizobium, especially if they are cultivated for first time field. For optimal results, highest-quality used. In our study, best were observed after Lupin which resulted highest protein content, across all treatments.
