During the 2025 growing season, a field experiment was conducted at the University of Agronomic Sciences and Veterinary Medicine of Bucharest to evaluate the effect of native soil microbiota on biological nitrogen fixation and seed yield in four white lupin (Lupinus albus L.) cultivars. The results showed that, even without artificial inoculation, plants developed an average of 10.59 nodules per root. The cultivars Medi and Mariuca exhibited the highest nodulation (11.33 and 11.15 nodules, respectively) and achieved the highest seed yields: 1,440 kg ha⁻¹ and 1,363 kg ha⁻¹. These values represent an increase of 13.11% and 7.06%, respectively, over the trial mean (1,273 kg ha⁻¹). A strong positive correlation (r = 0.962; R2 = 0.926) between nodule count and seed yield suggests that nodulation serves as a key indicator of nitrogen fixation potential and overall productivity. These findings indicate that native soil microbiota significantly support lupin development, with important implications for cultivar selection and sustainable crop management focused on reducing synthetic nitrogen inputs.
