The study of seed productivity play important role for successful introduction of the perspective medical plants as a Nigella sativa L. Introductive tests of this species were conducted at different levels above sea of cultivation in conditions of Dagestan. The results of investigation of N. sativa seed productivity depending on method of pollination are given in this work. It is revealed that free pollination is the main method, the proportion of which decreases in adverse conditions. It is also determined the decrease of average values for all traits as increasing of a high point of cultivation. The differences in fractional contribution of habitats on variability of fruit and seed characteristics under self pollination and open pollination are observed. The conditions of habitats control the high dependence of total productivity characteristics (mass of fruits, reproductive effort) for self pollinated plants, and characteristics of tip fruit and of the most vegetative traits for the plants with open pollination.
