A strict-field experiment determined the effect of four plant densities prior to harvest (49, 67, 89, 107 plants per sq. m) on the seed yield and yield components for traditional Nadwislanski and five self-completing Tim, Titus, Optimal, Rajan and Martin faba bean cultivars. Under poor soil conditions Nadwislanski yielded 16 percent higher than the self-completing cultivars. Favorable moisture conditions over vegetation period enhanced Nadwislanski predominance over the self-completing cultivars, however under moisture stress, especially over flowering, the difference in seed yield across the cultivar types studied was small. Traditional faba bean cultivar showed also the lowest seed yield range. An increased plant density from 49 to 67-107 plants per sq. m increased the seed yield significantlyhowever seed yield of Nadwislanski was independent of plant densitythe highest seed yield of Martin was obtained for at least 89 plants per sq. m, whereas for the other faba bean cultivars - at least 67 plants per sq. m was required
