The study covered traditional ‘Bardo’ and self-completing ‘Katon’ white lupin cultivars over 1998-2000 at the Mochełek Experiment Station. ‘Bardo’ cultivar yielded significantly higher than ‘Katon’. Urea applied together with MgSO4 (B) did not affect the seed yield of any cultivar studied. The addition of multi-nutrient Ekolist to the mixture of urea and MgSO4 (C) increased significantly the seed yield of ‘Bardo’, only. Chemical plant protection with Merpan and Ronilan (E) was the only one that resulted in the significantly highest seed yield of ‘Katon’. Neither foliar plant fertilisation nor chemical control affected the total protein content in seeds and their viability significantly.
