A split-factorial experiment on the basis of randomize complete block design with three replications was conducted in 2012, to assess the effects of different common bean (Phaseolus vulgaris L.) densities (0, 1, 2 and 4 per pot) and soil types (soil of wheat and barley fields) on some changes in germination and morphological traits of black seed (Nigella sativa L.). Results indicated that with increasing common bean density in soil of barely field, shoot length of black seed was significantly decreased. However, the lowest shoot length of black seed in soil of wheat field was obtained from the control density of common bean. In both of soil type day up to flowering of black seed was increased with increasing density of common bean. Maximum shoot dry weight and pod number of black seed in soil of barley and wheat fields was recorded under 2 and control density of common bean, respectively. Interaction of soil type and black seed density showed that the most shoot dry weight and day up to germination (germination rate) under barely soil was recorded in 2 densities of black seed. But, under wheat soil, those traits were obtained from 3 and 0 (control) densities. Pod number of black seed with increasing of this plant density was significantly declined.
