Abstract :
Abstract This research has been done to study the effects of plant population and arrangement on quantitative and qualitative characteristics of three different varieties of Nigella Sativa. The study was conducted in the form of factorial with completely random blocks designed with 4 replications at Saatloo Agricultural Station – W. Azarbaijan. In this research the first factors (A) contained two 20 and 40 cm inter-rows; the second factors (B) contained three 2, 4 and 6 cm intra -rows; and the third factors (C) contained three different varieties of Baft, Bukan, and Arbil. The specimens were planted on April 22nd, 2009. The results showed that the effects of plant population and arrangement harvest on capsules and total weight of stems, leaf weight, seed weight, oil percentage and seed efficiency were significant. Baft ranked in a good position in efficiency, but 1000-gram weight in Arbil variety was better. Seed efficiencies of inter-row 20cm, of intra –row 2cm, and variety of Baft were respectively equal to 1923.1, 2341.1, and 2148.1 kg/hec. On the whole Baft variety planted at 20 cm inter-row and 2 cm intra-row was the most efficient of Nigella Sativa.
